What is ticket reissue and revalidation?
Ticket revalidation and ticket reissue are the two ways an airline changes a ticket that has already been issued: revalidation keeps the original ticket number and amends the flight coupons on it, while reissue cancels that ticket and issues a new one, priced against the fares in force at the time, so the passenger may be asked to pay the difference. Both act on the ticket document rather than creating a fresh reservation, and which one a change needs depends on whether the new itinerary still satisfies the conditions attached to the original fare. The detail — the charge for the change, the fare that is applied, what happens to unused value and how long the amended ticket stays valid — comes from each airline's conditions of carriage and from the fare rules of the individual ticket.

Key takeaways
- Revalidation amends the coupons on the ticket you already hold; reissue replaces the ticket itself, so the ticket number changes.
- A change that breaks the conditions attached to the fare cannot simply be written onto the old ticket: American Airlines says a ticket is not valid where the dates of stay, purpose or status requirements of the fare are not met. [1]
- A new ticket brings a new validity clock. American measures a one-year validity from the date of first issue for an unused ticket, and from the first completed flight for a partly used one, unless the ticket states otherwise. [1]
- The fee for doing the work and the fare of the new itinerary are separate amounts in American's wording. [1]
- On award tickets, United says a service charge may be imposed for each change or cancellation requested after the award ticket is issued. [6]
What is the difference between revalidation and reissue?
A ticket is the record of the flights a passenger has bought, and it carries the conditions of the fare that was paid for them. American Airlines puts it this way: a ticket is valid only when the travel is to and from the cities shown on the ticket and the passenger meets all the requirements of the fare. [1]
Revalidation works inside that record. The airline keeps the ticket number and rewrites the coupons — typically the date or the flight number — so the passenger flies at a different time under the same ticket, with the same issue date and the same fare conditions still attached.
Reissue replaces the record. The old ticket is exchanged and a new ticket number is issued. Because the new ticket is priced afresh, the fare is the one available for the new itinerary, and the result can be higher, identical or lower than what was paid. That is why reissue is the operation that can produce an additional collection.
The reason the two are so often confused is that both are described as a "change" at the counter or on the website. The reliable test is the ticket number: if it survived, the ticket was revalidated; if a new number was issued, it was reissued.
American's glossary treats a fare as both the price paid for the ticket and the rules attached to that ticket, including whether it is refundable [1] — which is why the fare rule, not the change itself, is what usually decides the cost.
Which change needs which?
Revalidation is the lighter tool, and it only works while the new plan still fits the fare that was bought: the same routing, the same fare type, the same passenger, inside the conditions the fare allows.
Reissue is needed when the plan no longer fits — a different routing, a fare type whose conditions are not met, or a ticket rebuilt from value left over after a cancellation.
American's validity clause explains why the fare decides. American says a ticket is valid only when the 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 or official government business, and that a ticket is not valid where those requirements are not met. [1] Once the itinerary falls outside the fare, the existing coupons no longer describe a valid journey, and the correct handling is to price the itinerary against a fare the passenger does qualify for.
Why can a change with no fee still cost more?
A change can raise two different sums: an administrative charge for doing the work, and the fare of the new itinerary. Removing one does not remove the other.
American's conditions of carriage keep them apart. Its glossary defines automated re-shopping as using a robotic or automated process to re-book a ticket for the same passenger and itinerary on American in order to take advantage of a reduced fare where no change fee is payable to American for the administrative costs of the re-booking [1] — the administrative cost on one side, the fare on the other. American also lists automated re-shopping enabled or assisted by the passenger or an agent among prohibited booking practices, and reserves the right to cancel any unused part of the ticket, refuse carriage, decline a refund that would otherwise be due and charge what the ticket would have cost. [1]
On award tickets the money question is usually a service charge rather than a fare difference. United says 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, and that it may withdraw, limit, modify or cancel any award and increase the mileage, cash, applicable co-pays or number of certificates required for an award. [6]
How do the two interact with ticket validity?
A revalidation leaves the issue date alone, so the validity period attached to the ticket does not restart. A reissue starts a new ticket, and the question becomes which date the airline counts from — which is why no single rule fits every carrier.
American Airlines applies a one-year validity period, and its worked examples show what that means in practice. [1]
| Ticket state | What American applies |
|---|---|
| Unused | Travel must begin within one year of the date the ticket was first issued |
| Partly used | All travel must be completed within one year of the first completed flight |
| Unless | The ticket states otherwise |
An unused ticket issued on 1 June 2025 must be used to begin travel by 1 June 2026, and a round trip partly flown on 1 March 2026 must be completed by 1 March 2027. [1] Ticket validity is a different clock from the ticketing time limit, which governs how long a reservation can sit before a ticket is issued at all.
On award tickets, validity can be about route rather than date. United says awards for travel are valid only to destinations served both when the award ticket is issued and when the member departs, and that neither United nor its partners are liable for schedule changes that cancel service to a destination [6] — a limit no reissue can cure.
Whose validity rules apply can also depend on who operates the flight: British Airways says the General Conditions of Carriage applicable to flights booked on ba.com depend on the operator of the flight. [3]
Exceptions and limits
- A refund may be better than either option. American offers a full refund where a ticket is bought at least seven days before departure and the trip is cancelled within 24 hours of purchase, and follows different national rules where they apply. [1]
- When the airline moves the flight, different machinery applies. American refunds a non-refundable ticket, or the unused value of one, to the original form of payment if it cancels the flight or makes a schedule change of more than four hours to departure time [1], and states that for a cancellation, or a delay of three hours or more domestically or four hours or more internationally, its sole obligation is to refund the unused ticket value and optional fees under its involuntary refunds policy. [1] That is an involuntary change, not a reissue.
- Mistaken fares can be voided. If American sells a fare in error it may void the ticket and refund it in full, notifying the passenger within 72 hours of learning of the mistake, or at least 24 hours before departure where the ticket was bought less than 72 hours before departure. [1]
- Leftover value is not a ticket. American does not refund cash for a non-refundable ticket; where the passenger cancels before departure it cancels the ticket and issues a travel credit for future travel on American. [1]
- A ticket is not transferable. American says a ticket cannot be used by, or refunded to, another passenger, and that all refunds go to the original form of payment. [1]
- Award tickets follow the programme, not the ticket. United says miles are redeposited subject to a service charge when a redeemed award is cancelled or returned under the applicable rules and ticketed fare rules, that some awards are not eligible for redeposit and will say so [6], and that MileagePlus award tickets may be subject to the taxes, fees, tariffs, contract of carriage, ticket terms and re-accommodation policies of the carrier on which travel is scheduled. [6] The award ticket change checklist covers that route step by step.
Frequently asked questions
How long is an American Airlines ticket valid?
One year, generally: an unused ticket must begin travel within a year of first issue and a partly used ticket must be completed within a year of the first completed flight, unless the ticket states otherwise. [1]
Can a United MileagePlus award ticket be changed after it is issued?
Yes, but a service charge may be imposed for each change or cancellation requested by the member. [6]
What happens to the miles if I cancel a United award ticket?
They are redeposited to the account subject to a service charge, and some awards are not eligible for redeposit and will state so. [6]
Whose conditions apply if another airline operates the flight?
British Airways says the applicable General Conditions of Carriage depend on the operator of the flight [3], and United says MileagePlus award tickets may be subject to the ticket terms and re-accommodation policies of the carrier on which travel is scheduled. [6]
