TERMS OF SERVICE
Linear Air | Terms of Service
Effective Date: August 6, 2026 — Version 2026-08-06
BY PURCHASING TRAVEL SERVICES, OR ACCEPTING TRANSPORTATION, THE CUSTOMER AGREES TO BE BOUND HEREBY. These are the terms of service in effect as of the Effective Date above. The version of these Terms in effect at the time a reservation is booked governs that reservation, notwithstanding any later amendment.
1. All Operations Performed by FAA and Government Authorized Air Carriers
All flights are operated by U.S. 14 CFR Part 135 direct air carriers or other government approved air carriers ("operators"), the corporate names and trade names of which are disclosed to our customers prior to contracting for travel with an operator. Operators providing service for Air Taxi Service and Support LLC d/b/a Linear Air (and also referred to as ATSS) must meet standards set forth by the U.S. Federal Aviation Administration (FAA) and/or their local government authorization and by ATSS. If a contract for travel cannot be completed, ATSS will provide a timely refund of the full purchase amount. ATSS is an indirect air carrier as provided in U.S. 14 CFR Part 295 and does not manage or operate aircraft on behalf of our customers. Should any terms hereunder conflict with the applicable terms of an operator's terms and conditions, such terms will be superseded by the operator's terms, without affecting the applicability of all other terms and conditions hereunder.
2. Baggage & Claims
2.1 General
Baggage will be accepted for transportation from traveling customers only. ATSS will not accept baggage whose size, weight or character makes it unsuitable for transportation on the aircraft as determined by ATSS or an operator. All baggage is subject to inspection. Government safety and security regulations apply to carriage of baggage on trips booked via ATSS.
2.2 Bag Allowance
For each traveling customer, ATSS will allow baggage with a maximum total weight of 50 lbs per passenger. Bicycles, golf clubs and ski equipment are allowed, subject to operator-specific constraints. Carry-on may not be allowed given the interior stowage constraints of the aircraft. Excess baggage will be carried on a space available basis. Baggage compartment constraints of the aircraft may restrict the size of the bags that may be accepted for travel, regardless of weight.
2.3 Insurance and Limits of Liability for Baggage, Including Fragile or Perishable Goods
ATSS maintains non-owned aircraft liability insurance with a combined single limit bodily injury and property damage liability (including passengers) of $2,000,000 USD, including medical payment coverage of $10,000 USD per person. This insurance coverage describes ATSS's liability insurance in place and is not, by itself, a representation of the maximum amount recoverable by any customer for any claim; recoverable amounts remain subject to the specific liability limits set out in this Section 2.3 and applicable law.
Liability for loss, delay or damage to baggage is limited to $500 USD per passenger. This is the sole and exclusive baggage liability limit under these Terms; no other figure stated elsewhere in this document (including any general liability insurance figures referenced above) increases or supersedes this limit. Claims must be made via ATSS to the operator responsible for your flight.
ATSS and operators assume no responsibility for loss, damage or delayed delivery of baggage not acceptable for transport.
ATSS and operators assume no liability for fragile, valuable or perishable articles. Neither ATSS nor operators are liable for optics, keys, jewelry, money, silverware, negotiable papers, securities, books, documents, irreplaceable antiques, heirlooms, collectibles, artifacts, works of art, prescription medication, samples, photographs, electronic equipment, sound reproduction equipment, computer equipment, cellular phones, fragile articles or other similar valuable items and commercial effects included in baggage with or without the knowledge of ATSS and/or the operator. If any such items are lost, damaged, pilfered, or delayed, you will not be entitled to any reimbursement under this standard baggage liability limit.
Neither ATSS nor operators are liable for minor damage such as scratches, scuffs, stains, dents, cuts and dirt resulting from normal wear and tear.
2.4 Claims Restrictions, Including Time Requirements for Reporting or Filing Claims
Lost, delayed or damaged baggage must be reported to an ATSS customer service agent within four (4) hours of the arrival of the flight on which the loss, damage or delay is alleged to have occurred. All claims for any loss, damage or delay of checked baggage must be received by ATSS in writing within thirty (30) days of the incident which allegedly precipitated the loss, damage or delay. Any legal action must commence within one year of the incident. Otherwise, such claims will be considered waived.
ATSS assumes responsibility only for those claims arising from transportation of baggage arranged by ATSS. All claims are subject to proof of loss.
No action shall be maintained for any loss, damage, delay or pilferage of baggage, unless appropriate notice is given in accordance with this section. If notice is not given in accordance with this section or legal action is not commenced within one year from the date of the incident, any such claims will be considered waived.
2.5 Restricted Articles
U.S. Federal and other laws forbid the carriage of hazardous materials aboard aircraft in your baggage or on your person. A violation can result in five years imprisonment and penalties of $250,000 USD or more. (See 49 USC 5124.) Hazardous materials include explosives, compressed gases, flammable liquids and solids, oxidizers, poisons, corrosives and radioactive materials. Examples include: paints, lighter fluid, fireworks, tear gases, oxygen bottles and radiopharmaceuticals. There are special exceptions for small quantities (up to 70 ounces total) of medicinal and toilet articles carried in your luggage and certain smoking materials carried on your person. For further information, contact ATSS.
U.S. Federal and other laws provide that no person shall carry a deadly or dangerous weapon, either concealed or unconcealed, aboard any ATSS booked aircraft except: (1) employees or officials of a municipality or State, or the United States, who are authorized to carry firearms (e.g. FBI, Secret Service, LEO prisoner escort, Federal Air Marshall) or (2) crew members and other persons authorized by the operator to carry firearms. Appropriate documentation and identification will be required of any passenger traveling under this provision. Firearms that are unloaded, dismantled and encased in a hard-sided suitable locked container may be carried as checked baggage, subject to operator-specific procedures. Ammunition must be securely packaged in a container made of durable fiber, wood or metal, or in the manufacturer's original package to a maximum not exceeding eleven (11) pounds. The passenger will be required to complete the applicable declaration forms.
2.6 Live Animals
Live pets are accepted for transport subject to the conditions noted herein. Pets must be accompanied by a traveling passenger, as pets will not be accepted unaccompanied. Customer must inform ATSS of any pets traveling at time of booking. Only one pet per aircraft is permitted on shared charter flights. See also Service Animals under Section 3.4.
On most ATSS arranged flights, passenger must provide a kennel suitable for transport of the pet. Kennels for large pets may not fit in the aircraft and the customer should contact ATSS directly for information regarding size constraints.
If kennels are not required, dogs may travel as follows, subject to operator-specific requirements: dogs not exceeding 35 pounds in weight may be carried on the passenger's lap; dogs exceeding 35 pounds in weight must be properly restrained with a leash, harness or similar device; specific seating arrangements apply to accommodate non-kenneled live animals in the aircraft cabin.
The animal must be harmless, odorless, inoffensive and suitable for cabin air transport as determined by ATSS and/or the operator. A passenger assumes full responsibility for the safety, well-being and conduct of his or her pet while on board the aircraft, and for compliance with all governmental requirements or restrictions of the country, state, or territory from and/or to which the animal is being transported. Upon arrival, health certificates may be required by local authorities, depending upon the route over which the pet is traveling. Additional fees may be assessed at the operator's discretion if the pet's carriage reasonably results in the necessity of extraordinary post-flight cleaning. ATSS assumes no responsibility for the impaired health or death of the animal.
3. Acceptance of Customers
3.1 Refusal to Transport
ATSS may refuse to book transport for, refuse to authorize the commencement of an already-booked trip for, or may request that an operator remove at any point, any passengers: when necessary to comply with government regulations; when necessary for the safety and/or comfort of themselves or other passengers; or when the customer's conduct is disorderly, abusive, or violent towards other customers or ATSS or operator employees.
3.2 Disabled Individuals
ATSS coordinates with its operator partners so that disabled individuals may be transported in accordance with applicable Federal Aviation Administration (FAA) regulations and other applicable law. ATSS defines disabled individual as any passenger needing special assistance and/or consideration because of physical or mental limitations such as blindness, deafness, mental handicap (not so severe as to endanger the safe operation of the flight), advanced age, senility, heart conditions, etc. Passengers who, because of age, mental or physical condition, disability or impairment, require individual attention (enplaning, deplaning, during flight and/or during emergency evacuation, or during ground handling at an airport) will be afforded a reasonable amount of assistance, in accordance with the assigned operator's policies.
ATSS may decline to book transportation for any customer on the basis of safety, and may decline to book transportation for any customer whose carriage would violate U.S. Federal or other regulations or the policies of the operator for that trip. In exercising this authority, ATSS personnel will not decline transportation to any disabled individual solely on the basis of the disability.
If more than one disabled individual is traveling on the same flight, ATSS will, in its sole discretion and in cooperation with the operator for that flight, determine whether all may travel on the same flight, as per the policies of the operator for that trip and in the interest of safety. Special seating requirements may apply.
Fully collapsible wheelchairs will be carried free of charge. Electric wheelchairs are carried free of charge, one per aircraft, when consistent with space and weight constraints. Wet cell batteries must be disconnected, terminals insulated, and stored in strong, rigid packaging. The box must be clearly marked as enclosing such item with arrows indicating the "up" position. Regulation battery boxes are highly recommended.
3.3 Unaccompanied Minors
Unaccompanied minors are minors at least five (5) years of age and under the age of eighteen (18) who are traveling alone and will be accepted for transportation as follows:
- Minors under the age of five (5) are not accepted for travel unaccompanied.
- Parents or guardians may request a child of any age be escorted as if he or she were an unaccompanied minor.
- Escort service fees may apply.
- The unaccompanied minor must be brought to the airport by a parent or other responsible adult, who must furnish ATSS with the name, address, and phone number of the parent or other responsible adult who will meet the unaccompanied minor upon deplaning at the minor's destination.
- The responsible adult previously named and furnished to ATSS must show proper identification in order for the unaccompanied minor to be released into his or her custody at the final destination.
- ATSS reserves the right to decline to authorize the commencement of transportation if it believes there is a significant chance that the flight on which the unaccompanied minor holds a reservation may terminate at an airport other than the minor's destination.
- Unaccompanied minors will be in the presence of a representative of the contracted operator at all times. In the event of flight cancellation, diversion, substantial delay, or other irregularity, ATSS and/or the operator will attempt to contact the responsible adults identified on the request for carriage form, and priority accommodations will be provided for the minor.
- ATSS assumes no responsibilities for unaccompanied minors beyond those applicable to an adult customer.
3.4 Service Animals
ATSS will permit dogs and other service animals used by qualified disabled individuals to accompany the person on a flight free of charge. Kennels are not required, although the animal must be properly restrained in a harness or similar device. Specific seating arrangements apply to accommodate unkenneled live animals in the aircraft cabin. A passenger assumes full responsibility for the safety, well-being, and conduct of his or her service animal while on-board the aircraft, and for compliance with all governmental requirements or restrictions of the country, state, or territory from and/or to which the animal is being transported. Additional fees may be assessed at the operator's discretion if the service animal's carriage reasonably results in the necessity of extraordinary post-flight cleaning.
4. Reservations
4.1 Passenger Manifest
No person will be entitled to transportation except upon presentation of a valid ID (see Section 13, Required Documents) with a name matching the passenger reservation manifest for each flight. Any passenger-initiated changes to such transportation may result in a change in price, assessment of monetary penalties, or loss of transportation value.
Reservations are non-transferable. ATSS is not liable to the owner of a reservation for honoring such a reservation when presented by another person.
4.2 Fees and Taxes
A U.S. Federal excise tax and a per-passenger segment tax apply to each U.S. domestic occupied flight segment on aircraft not qualifying for the small aircraft exemption under 26 U.S.C. § 4281, all turbojet aircraft, and shared charter service, as applicable, at the rates then in effect under U.S. Federal law and Internal Revenue Service regulations. These rates are adjusted periodically by the IRS; the currently applicable rates will be reflected at time of booking rather than stated here as fixed figures. Taxes in other countries and local jurisdictions may apply to your flight as well.
4.3 Payment
All travel must be pre-paid. A reservation is not a confirmed booking until payment is received in full. Until payment is received, ATSS may release any hold and rebook the aircraft or seat to another customer without notice or liability to the prospective customer.
4.4 Charter Flights: Cancellation or Changes by Customer
Customer acknowledges that Linear Air and its operator partner(s) incur both monetary and opportunity costs when a customer books a trip. Linear Air's standard cancellation policy is as follows: Customers who cancel more than forty-eight (48) hours prior to scheduled departure will receive the full amount on credit for future travel within twelve (12) months. Cancellations made between forty-eight (48) and twenty-four (24) hours prior to the scheduled departure time will incur a charge equal to one-half of the trip price, with the remaining funds kept on account. Cancellations made within twenty-four (24) hours of the scheduled departure time will incur a charge of the full trip price. No cancellation will result in a charge greater than the full trip price. However, cancellation terms may differ depending on trip profile and aircraft category — for the categories below, the timeline for reaching that maximum charge may be shorter than the 48/24-hour structure above, based on the terms secured from the operator for that flight. Itineraries with stricter operator-specific cancellation cutoffs include turbine (jet and turboprop), one-way, multi-day, international, and flights on peak travel days. Linear Air may, in its sole discretion, issue a full or partial refund — in the form of a cash refund or credit on account, as Linear Air determines — in consideration of extenuating circumstances, subject to agreement(s) made with our operator partners.
Customers have the flexibility of scheduling their flights for any time they choose and thus are expected to be on time. If the operator's schedule allows the airplane to wait for a passenger who is late, ground wait charges may apply. In cases when the operator's schedule does not allow the airplane to wait, the passenger will be charged for the flight as if it had been conducted as booked.
Linear Air will attempt to accommodate changes in departure date or time, passengers, departure/arrival airport, or aircraft type requested by the customer. If Linear Air is unable to accommodate customer-requested changes, the customer may cancel in accordance with the terms herein. Credits on account expire after 12 months.
4.5 Share and Save Shared Charter Per-Seat Flights: Cancellation or Changes by Customer
Cancellations made more than forty-eight (48) hours before the flight will result in the price of the shared charter flight being credited to the customer's ATSS account for future travel within the next 12 months. After 12 months, the credit will expire.
If the customer cancels a reservation within forty-eight (48) hours of departure, the price of the shared charter flight will be forfeited.
Customers who have booked a flight leg on a per-seat basis may be allowed, at ATSS's sole option, to pay a fee to change the departure time of the flight leg. Such changes may only be requested within forty-eight (48) hours of departure. The fee shall be equal to the highest price for a seat on that flight leg. Should ATSS accept the fee and change the departure time, ATSS will continue to market unsold seats, if any, on that flight leg, departing at the new time. Subsequent requests to change the departure time, including requests to return it to the originally scheduled time, will be treated like the initial request and will incur additional fees if accepted by ATSS.
Similarly, customers who have booked a flight leg on a per-seat basis may be allowed, at ATSS's sole option and subject to operator availability, to pay the difference between their per-seat fare and the then-current whole-aircraft charter price in order to convert the per-seat booking into a charter of the whole aircraft.
If the reservation is partially unused, the credit to the customer's ATSS account will be the difference between the amount paid and the value of the transportation actually used, as determined by the applicable rules, less any applicable service charge or penalty. No refund is due on any shared charter/per-seat travel except as ATSS may determine below. ATSS may, in its sole discretion, issue a full or partial refund — in the form of a cash refund or credit on account, as ATSS determines — in consideration of extenuating circumstances.
4.6 Cancellation or Changes by ATSS or the Operator
Passengers who have not checked in and are not at the boarding point ready to board the aircraft at least fifteen (15) minutes before the scheduled departure time are subject to having their reservation for that flight canceled, as well as all other reservations in their itinerary.
When a passenger fails to honor a segment of a reservation, ATSS may cancel, without notification, all continuing and returning portions of the itinerary contained in the same reservation record.
If ATSS's refusal to transport the customer is for reasons defined in Section 3.1, the reservation will be canceled.
In the event that ATSS or the operator cancels a flight or fails to provide a previously confirmed seat and does not reroute the customer either over other ATSS flights or those of another operator, ATSS will refund directly to the customer:
- An amount equal to that paid if no portion of the reservation has been used; or
- An amount equal to the applicable charge for the unused segment(s) if a portion of the reservation has been used. In no instance will the amount refunded be greater than the amount paid for the reservation.
- No refund will be made if ground or sea transportation is offered for part of the itinerary and accepted by the customer.
- The applicable refund will be granted only if the customer complies with the provisions set forth in these Terms.
Customers on flights canceled by ATSS or the operator, where the customer does not accept an offer of substitute transportation via the next available flight or ground/sea transportation, will be offered a refund.
4.7 Pricing
All prices are subject to change without notice, except that the price for a reservation already booked and paid for will not change after booking, absent a customer-initiated change described elsewhere in these Terms.
The price charged on any reservation applies only to the transportation specified thereon. Any passenger-initiated changes to such transportation may result in a change in the price, assessment of monetary penalties, or loss of transportation value.
5. The Arrow Club by Linear Air
A complete set of terms and conditions for the Arrow Club by Linear Air can be found at: www.linearair.com/terms/arrow-club
6. Flight Delays and Re-Routings
ATSS undertakes to use reasonable effort to arrange the expeditious transport of all customers and baggage.
6.1 Irregularities
Irregularities include:
- Delay in a departure or arrival of an ATSS-booked flight resulting in misconnection.
- Flight cancellation or any other delay or interruption in the operation of an ATSS-booked flight.
- Changes that require re-routing of the customer at departure time, because prior notice of such change had not been given to the customer prior to the customer's arrival at the airport for the original flight.
Irregularity does not include a Force Majeure event as defined in Section 6.2.
When a customer will be delayed because of an irregularity involving an ATSS-booked flight, the following will apply:
- ATSS will arrange for the transport of the customer on the next flight on which space is available.
- ATSS may at any time, with the concurrence of the customer, arrange for the customer's transportation with an operator other than the one originally booked, provided ATSS has an agreement with that operator for such transportation.
- If ATSS is unable to arrange alternate transportation acceptable to the customer, ATSS will refund the cost of the unflown portions in accordance with Section 4.6.
6.2 Force Majeure
Events include:
- Any condition beyond ATSS's or an operator's control (including, without limitation, meteorological conditions, acts of God, airport traffic congestion, FAA or governmental or air traffic control flight restrictions, delays, riots, embargoes, hostilities, or unsettled international conditions, whether actual, threatened, or reported), or any delay, demand, circumstance, or requirement due, directly or indirectly, to such a condition.
- Any labor dispute affecting ATSS's or an operator's service.
- Any government regulation, demand, or requirement.
- Any shortage of labor, fuel, or facilities of ATSS or others.
- Any other fact not reasonably foreseen, anticipated, or predicted by ATSS or an operator.
ATSS or the operator it has booked, as applicable, may, in the event of a force majeure event, without notice, cancel, terminate, divert, postpone, or delay any flight or reservation and determine whether any departure or landing should be made, without liability except to refund any unused portion of the reservation.
6.3 Amenities for Delayed Customers
ATSS will attempt to communicate frequently and keep the customer informed as to the nature of delayed flights.
No amenities or compensation will be provided to a customer on a flight that is delayed or cancelled at the customer's origination point or destination, or that is delayed or cancelled due to a force majeure event.
6.4 Additional Charges
The price quoted for a charter reflects the anticipated cost of the flight as booked. In certain circumstances, the operator may impose additional charges on ATSS beyond the originally quoted price — for example, in connection with de-icing, additional ground or air time resulting from weather, air traffic control delays, airport congestion, or other factors beyond ATSS's or the operator's control, or other operational costs incurred in connection with the flight. ATSS reserves the right to pass any such additional operator-imposed charges through to the customer.
Because these charges may not be known or finalized by the operator until after the flight has occurred, ATSS may charge the card on account for such amounts after the fact. ATSS will provide the customer an explanation of any such charge upon request.
7. Oversold Seats (Share and Save Flights)
On Share and Save shared charter (per-seat) flights, ATSS does not intentionally oversell available seats; however, an oversell may occur due to reservation system errors or similar circumstances. If this occurs, ATSS will first request volunteers to relinquish their seat in exchange for credit or other compensation, determined at ATSS's discretion. If no volunteers come forward, ATSS will select the affected passenger(s), which may take into account factors such as disability or hardship, and will arrange the next available transportation for that passenger. This section does not apply to whole-aircraft charter bookings, which are not subject to inventory oversell.
8. Smoking
Smoking is prohibited on all ATSS arranged or booked flights.
9. Limitation of Liability
Except for the baggage liability limit set out in Section 2.3 and as otherwise required by applicable law, ATSS's aggregate liability to any customer arising out of or relating to a reservation or flight shall not exceed the amount actually paid by the customer for the affected transportation, except in cases of ATSS's gross negligence or willful misconduct. This limitation does not apply to the operator's own liability as the direct air carrier, which is governed by the operator's terms and applicable law.
10. Governing Law; Venue
These Terms, and any dispute arising out of or relating to them or to any transportation arranged by ATSS, are governed by the laws of the Commonwealth of Massachusetts, without regard to its conflict-of-laws principles. Any action or proceeding arising out of or relating to these Terms shall be brought exclusively in the state or federal courts located in Suffolk County, Massachusetts, and each party consents to the exclusive jurisdiction and venue of such courts.
11. Severability
If any provision of these Terms is held by a court or agency of competent jurisdiction to be invalid or unenforceable, that provision shall be enforced to the maximum extent permissible, and the remaining provisions of these Terms shall remain in full force and effect.
12. Right of ATSS to Change These Terms
ATSS reserves the right to change these Terms at any time. Changes will be posted with an updated Effective Date and version number. The version of these Terms in effect at the time a reservation is booked governs that reservation.
13. Required Documents

It is the passenger's responsibility to obtain visas, where required, from the appropriate embassy or nearest consulate of the country or countries being visited, including any connecting countries.
Each passenger desiring transportation across any international boundary is responsible for obtaining all necessary travel documents and for complying with the laws of each country from, through, or to which he or she desires transportation, and, unless applicable law provides otherwise, shall indemnify ATSS and each operator for any loss, damage, or expense suffered or incurred by ATSS and/or such operator by reason of the passenger's failure to do so. Neither ATSS nor any operator shall be liable for any aid or information given by any agent or employee of such organization to any passenger in connection with obtaining such documents or complying with such laws, whether given orally, in writing, or otherwise, or for the consequences to any passenger resulting from his or her failure to obtain such documents or to comply with such laws. If the passenger does not have the required documentation and identification for his or her destination, he or she will not be allowed to board the aircraft.
