FREQUENT FLYER GLOSSARY

What is an involuntary change?

Involuntary change (also involuntary rebooking or a carrier-initiated change) is an alteration an airline makes to a booking the passenger did not ask for — a retimed or cancelled flight, a misconnection caused by the carrier's own delay, or a downgrade to a lower cabin. What the passenger is owed for one depends on the rules that govern the ticket, not on a single worldwide standard. [1] [2] [3]

Key takeaways

  • Who made the change decides the label: refunds, re-routing and compensation attach to changes the carrier makes, not to ones the passenger requests. [1] [2] [3]
  • In the United States, the Department of Transportation requires a refund when an airline cancels a flight, or significantly delays or changes one, and the passenger chooses not to travel. [2]
  • American Airlines' conditions of carriage state that the flight schedule is not guaranteed and is not part of the contract, then set out separate rebooking and refund commitments. [1]
  • EU rules treat certain retimings as cancellations and reimburse a percentage of the ticket price when a passenger is downgraded. [3]

What makes a change involuntary?

A change is involuntary when the airline alters the booking and voluntary when the passenger asks for the alteration. The distinction matters because disruption protections are triggered by what the carrier did, while a passenger-initiated change is governed by the fare rules of the ticket instead.

American Airlines lists the adjustments it may make between booking and departure: the flight number, the type of aircraft and its available amenities, the seat assignment, the airline operating the flight, the origin or destination airport, the number of stopovers or stopover cities, and departure or arrival times. [1]

Some carrier-initiated changes are easy to misread. Under EU air passenger rights a flight counts as cancelled when the original schedule is abandoned and the passenger is transferred to another scheduled flight, when departure is brought forward by more than one hour, when the aircraft takes off but returns to the departure airport and the passenger is transferred to another flight, or when the flight lands at an airport other than the ticketed final destination — unless the passenger accepted re-routing, or both airports serve the same town or region, in which case it is treated as a delay. [3] A departure moved earlier, not later, can therefore count as a cancellation.

At the opposite end sits the passenger's own decision. US rules require airlines to allow a full refund, or a free hold, within 24 hours of purchase for tickets bought at least seven days before departure — a right that exists whatever the airline does. [2]

What does American Airlines' contract of carriage promise?

The American Airlines conditions of carriage, updated 13 August 2026, say the airline does its best to be on time but that its flight schedule is not guaranteed and is not part of the contract, and that it is not liable when it is late, when a passenger misses a connection, when it changes the schedule of a flight, or when it or a partner cancels a flight or route. [1]

When a change or cancellation affects a trip, American says it will try to contact the passenger in advance to rebook another flight or move them to a similar seat or cabin, though it makes no guarantees. [1] It rebooks on the next American flight with available seats at no additional cost and, if no American flights are available until the next day and the disruption was caused by the airline, on a partner airline at no additional cost, in the originally ticketed cabin. [1]

If American or a partner airline cancels the flight, or departure or arrival is delayed by three hours or more on a domestic itinerary or four hours or more on an international one, American says its sole obligation is to refund the unused ticket value and any optional fees under its involuntary refunds policy. [1] A refund is also made where the passenger rejects the alternative arrangements or none were available. [1] The itinerary changes American lists as making a ticket refundable are a change of three hours or more (domestic) or four hours or more (international), a change of origin or destination airport, a downgrade to a lower cabin, and an increased number of connections. [1]

Someone who chooses to travel in a lower cabin is refunded the difference between the original fare and the fare for the cabin flown on the affected segment. [1] A non-refundable ticket is refunded to the original form of payment when American cancels the flight, or when a schedule change moves departure by more than four hours. [1] Involuntary denied boarding on an oversold flight is a separate mechanism, and American excludes compensation where it switches to a smaller aircraft for safety or operational reasons. [1]

What does the US Department of Transportation require after a significant change?

The Department of Transportation says a consumer is entitled to a refund of the ticket price when the airline cancels a flight, whatever the reason, and the consumer chooses not to travel or not to accept credits, vouchers or other compensation; the same applies when an airline significantly delays or significantly changes a flight and the consumer chooses not to travel. [2] That refund right falls away if the passenger takes the changed or alternative flight, although compensation for expenses may still be available where the disruption was within the airline's control. [2]

What counts as a significant change or delay under US rules, as of 7 November 2025
Type of changeThreshold
Early departureDeparture three hours or more earlier than scheduled on a domestic itinerary, or six hours or more on an international one. [2]
Late arrivalArrival three hours or more later than scheduled on a domestic itinerary, or six hours or more on an international one. [2]
Airport changeA different origin or destination airport. [2]
More connectionsMore connection points than the original itinerary. [2]
DowngradeAn involuntary move to a lower class of service. [2]
Disability-relatedDifferent connecting airports, or a substitute aircraft without an accessibility feature the passenger needs. [2]

A downgraded passenger who decides not to travel is entitled to a refund; one who travels is entitled to the difference between the original fare and the downgraded fare. [2] Refunds must be automatic where the passenger does not accept the airline's alternatives, within seven business days for credit card purchases and 20 calendar days for other payment methods. [2] Airlines must tell passengers about the refund right, credits or vouchers offered instead must be valid for at least five years with any material restrictions disclosed, and where a ticket agent is the merchant of record the agent issues the refund. [2] The Department of Transportation does not require airlines to rebook passengers on alternative flights, though they often offer to. [2]

What are your rights under EU air passenger rights?

EU air passenger rights cover flights within the EU operated by an EU or non-EU airline, flights arriving in the EU from outside operated by an EU airline, and flights leaving the EU for a non-EU country operated by either, provided the passenger has not already received benefits for the same journey under a non-EU country's law; the rules also apply to flights to and from Iceland, Norway and Switzerland. [3]

For a cancelled flight the passenger chooses between reimbursement of the ticket, re-routing at the earliest opportunity, or re-routing later at their convenience, and is entitled to assistance at the airport. [3] Where the airline gave less than 14 days' notice, compensation is due unless it proves extraordinary circumstances, and it is also not due where notice was between 2 weeks and 7 days and re-routing was offered departing no more than 2 hours early and arriving less than 4 hours late, or where notice was under 7 days and re-routing was offered departing no more than 1 hour early and arriving less than 2 hours late. [3] For a cancellation, compensation is set by distance for flights up to 1,500 km, for flights over 1,500 km within the EU and other flights between 1,500 and 3,500 km, and is EUR 600 for flights over 3,500 km. [3] A delay of three hours or more at the final destination also triggers compensation unless extraordinary circumstances apply; for a delay at arrival, compensation is determined by distance: a set amount for flights up to 1,500 km with a delay of three hours or more, a set amount for flights over 1,500 km within the EU and other flights of 1,500–3,500 km with a delay of three hours or more, EUR 300 for flights over 3,500 km with a delay of at least three but less than four hours where the flight either departs the EU to a non-EU country or departs a non-EU country to the EU and is operated by an EU airline, and EUR 600 for flights over 3,500 km with a delay of four hours or more. [3] Once the passenger has chosen one of the three options for a cancellation, the other two no longer apply. [3]

Reimbursement when a passenger is downgraded
FlightShare of the ticket price
1,500 km or less30% [3]
Within the EU over 1,500 km, except between the EU and French overseas departments, and all other flights between 1,500 and 3,500 km50% [3]
All other flights, including between the EU and French overseas departments75% [3]

Where a single ticket contains two or more connecting flights, only the downgraded flight is reimbursed, and payment is due within seven days; an upgrade cannot carry an extra charge. [3] A missed connection gives a right to compensation when the flights were booked as part of a single reservation, EU rules apply, arrival at the final destination is delayed by more than three hours and extraordinary circumstances were not the cause — but not where the connection was missed because of security queues or a failure to respect the boarding time. [3]

Exceptions and limits

  • Extraordinary circumstances (EU). Air traffic management decisions, political instability, adverse weather and security risks are examples of extraordinary circumstances that can remove the compensation entitlement, while most technical problems found during maintenance, a collision between mobile boarding stairs and an aircraft, and internal strikes by the carrier's own staff are not; a strike external to the carrier may count. The airline must show the link between the event and the disruption and that it could not have been avoided. [3]
  • Force majeure (American Airlines). Weather, civil disturbances, acts of terror, public health emergencies, labour disputes, government requirements and shortages of labour, fuel or facilities fall within American's force majeure clause; if the ticket still has value the unused portion is refunded to the original form of payment, but the airline says it is not liable beyond that, and its contract excludes special, incidental and consequential damages from schedule changes. [1]
  • Two flights, one reservation. EU rules treat the outbound and return flights as two separate flights even when booked together, and only the airline operating the flight can be held responsible. [3]
  • Which law applies. American's contract states that Texas law governs it to the extent not preempted by federal law, while the EU definition of "EU" covers the 27 member states plus Guadeloupe, French Guiana, Martinique, Mayotte, Réunion, Saint Barthélemy, Saint-Martin, the Azores, Madeira and the Canary Islands, but not the Faroe Islands. [1] [3]

Frequently asked questions

Does a schedule change count as a cancellation?

Under EU rules it does in four situations: the original schedule is abandoned and you are transferred to another scheduled flight, departure moves earlier by more than one hour, the aircraft returns to its departure airport and you are transferred to another flight, or you land at an airport other than the ticketed final destination. [3] US rules treat cancellations and significant delays or changes as separate grounds, both giving a refund right when the passenger does not travel. [2]

Can I get a refund if the airline moves my flight by two hours?

A two-hour move falls below the US thresholds for a significant change, which start at three hours for domestic itineraries and six hours for international ones. [2] American Airlines lists itinerary changes of three hours or more (domestic) or four hours or more (international) among the changes that make a ticket refundable. [1]

What am I owed if I am downgraded but still fly?

Under US rules the airline refunds the difference between the original fare and the downgraded fare. [2] American refunds the difference between the original fare and the fare for the cabin flown on the affected segment. [1] Under EU rules the reimbursement is a percentage of the ticket price, 30%, 50% or 75% by distance, paid within seven days. [3]

Must the airline rebook me on another carrier?

The Department of Transportation does not require airlines to rebook passengers on alternative flights, though they often offer to. [2] American rebooks on its own next flight with seats at no additional cost, and on a partner airline when no American flight is available until the next day and the disruption was its fault. [1] EU rules give a choice between reimbursement, re-routing at the earliest opportunity and re-routing later. [3]
