What is a voluntary change?

What counts as a voluntary change?

A voluntary change starts with the passenger. The ticket has already been issued and paid for, and the traveller wants to move the trip: another day, another departure time, another routing, another cabin. Nothing has gone wrong on the airline's side, so the request runs through the terms of the ticket that was sold rather than through the airline's own rebooking commitments.

An involuntary change runs the other way. American Airlines lists the adjustments it may make between booking and departure: flight number, aircraft type and available amenities, seat assignment, the airline operating the flight, the origin or destination airport, the number of stopovers or stopover cities, and departure or arrival times. [3] Where American cancels the flight, or departure or arrival is delayed by 3 or more hours on a domestic itinerary or 4 or more hours internationally, the carrier says its sole obligation is to refund the unused ticket value and any optional fees under its involuntary refunds policy. [3]

American's conditions of carriage, as updated on 13 August 2026, subject every ticket to the terms printed on the ticket or ticket receipt, to published fare rules and to applicable tariffs filed with the U.S. Department of Transportation, all of which are incorporated into the agreement with the passenger. [3] The glossary inside those conditions defines a fare as the price paid plus the rules associated with that ticket, including whether it is refundable. [3] The price paid is therefore only part of the answer; the rules attached to that price are the rest.

Which fare rule terms govern a voluntary change?

Two parts of the ticket terms bear on a voluntary change: how long the ticket stays valid, and which fare requirements the travel still has to satisfy.

Validity. American tickets are generally valid for one year. An unused ticket must be used to begin travel within one year of the date it was first issued, and a partly used ticket must complete travel within one year of the first completed flight — unless the ticket states otherwise. American's own example is an unused ticket issued on 1 June 2025, which must begin travel by 1 June 2026. [3]

Fare requirements. American says a ticket is valid only when travel is to and from the cities on the ticket and the passenger meets all fare requirements, which may include dates of stay such as a Saturday night, military status for a military fare, official government business for a government fare, or attendance at an event for a meeting or convention fare. A ticket is not valid where those dates of stay, purpose or status requirements are not met. [3]

The edge of the rule. American prohibits reservations made to exploit or circumvent fare and ticket rules, and lists hidden-city ticketing, back-to-back ticketing, holding reservations to secure upgrades or block seats, and duplicate or impossible trips among the examples. Where it finds evidence of such a practice, American reserves the right to cancel any unused part of the ticket, refuse carriage and check bags, and not refund an otherwise refundable ticket. [3]

Is it a change fee or a fare difference?

American's conditions of carriage use the term change fee in the glossary definition of automated re-shopping, which reads: "The use of a robotic or automated process of re-booking a ticket for the same passenger and itinerary on American with the purpose of taking advantage of a reduced fare where there is no change fee payable to American for the administrative costs of the re-booking." [3] The wording separates the reduced fare being sought from a change fee payable to American for the administrative costs of the re-booking, and the practice it describes applies where no such change fee is payable. [3]

That distinction matters because American incorporates published fare rules into its conditions of carriage and defines a fare as the price paid plus the rules associated with the ticket, including whether it is refundable. [3] The fare rule for the ticket that was issued therefore governs the change. [3]

Where a traveller would rather abandon the trip than move it, American's rule for non-refundable tickets applies: it does not refund cash, but if the trip is cancelled before departure it cancels the ticket and issues a travel credit toward future travel on American. [3] Refundable tickets work differently — the full amount where travel has not started, and the value of unused travel where the ticket is partly used. [3]

When a missed flight closes the option

The conditions of carriage that carry the fare rule also set the check-in and boarding cut-offs, and they state what the airline may do with a seat when those cut-offs pass.

American asks passengers to be checked in at least 45 minutes before scheduled departure on flights within the U.S. and at least 60 minutes before scheduled departure on flights to or from airports outside the U.S., with some airports requiring earlier check-in. A passenger who is not checked in by the minimum check-in time may have their seat reassigned to another passenger. [3] Passengers must be at the gate and ready to board at least 30 minutes before departure on domestic flights and 45 minutes before departure on international flights, and boarding ends 15 minutes before departure; anyone not on board may have their seat reassigned, and boarding is not allowed once the doors close. [3]

Both sets of times sit in the same document as the fare rule, so they are worth reading before deciding whether to change a trip or let the flight go.

Exceptions and limits

• The 24-hour exit. American generally allows up to 24 hours from purchase for a full refund where the ticket was booked at least 7 days before departure, provided the trip is cancelled within 24 hours of purchase; tickets bought through a travel agency or another booking source are refunded by that source, and some countries have different rules. [3]
• When the airline moves first. American promptly and automatically refunds the ticketed fare including taxes and fees where it cancels a flight or makes a significant itinerary change and the customer chooses not to fly, including itinerary changes of 3 or more hours domestically or 4 or more hours internationally, changes of origin or destination airport, downgrades to a lower cabin and an increased number of connections. [3]
• Refunds to the original form of payment. American also refunds to the original form of payment where it cancels the flight, where a schedule change moves departure by more than 4 hours, where a passenger or their travel companion dies, and where military orders require cancellation, with supporting paperwork where required. [3]
• Tickets sold in error. American reserves the right to cancel a ticket sold in error, including fare errors, computer errors and third-party errors, voiding it with a full refund and notice within 72 hours of learning of the error, or at least 24 hours before departure where the ticket was bought less than 72 hours before departure. [3]
• Award tickets. Award changes are program-specific and sit outside this page. United Airlines' MileagePlus rules state that after an award ticket or other award is issued, a service charge may be imposed for each change or cancellation requested by the member. [6]

Frequently asked questions

Is a voluntary change the same as an involuntary change?

No. A voluntary change is requested by the passenger, while an involuntary change is made by the airline. When American Airlines cancels a flight or delays departure or arrival by 3 or more hours domestically or 4 or more hours internationally, its stated sole obligation is to refund the unused ticket value and optional fees under its involuntary refunds policy. [3]

How long is an American Airlines ticket valid if I want to move my travel date?

Generally one year: an unused ticket must begin travel within one year of the date it was first issued, and a partly used ticket must complete travel within one year of the first completed flight, unless the ticket states otherwise. [3]

Can I get a refund instead of a change on a non-refundable ticket?

American Airlines does not refund cash for non-refundable tickets; if the trip is cancelled before departure it cancels the ticket and issues a travel credit toward future travel on American. [3] A full refund is available within 24 hours of purchase where the ticket was booked at least 7 days before departure and the trip is cancelled in that window. [3]

What happens if I miss the check-in cut-off?

American sets check-in deadlines of 45 minutes before scheduled departure within the U.S. and 60 minutes before departures to or from airports outside the U.S., with earlier deadlines at some airports, and a passenger who is not checked in by then may have their seat reassigned. [3] Boarding ends 15 minutes before departure. [3]

Do award tickets follow the same change rules?

No. Award changes are governed by each programme's own rules; United Airlines' MileagePlus rules state that after an award ticket is issued, a service charge may be imposed for each change or cancellation the member requests. [6]
