Flight Rebooking & Cancellation Guide

Your travel dates changed. Or you found a better connection. Now what? Rebooking sounds simple, but the rules differ wildly between airlines and fare types. Sometimes it is free. Sometimes it costs more than just buying a new ticket. This guide walks you through when each option makes sense and how to avoid losing money unnecessarily.

When can you rebook for free?

Three situations where you can change your flight without paying extra:

Flex fares or Business Class: Most airlines offer flexible fare options. They cost more upfront but allow unlimited changes without rebooking fees. If there is any chance your schedule might shift, buying a flex fare is often cheaper in the long run.

The 24-hour cancellation rule (US flights): Booked with a US-based airline, or is your flight departing or arriving in the United States? US Department of Transportation rules require airlines to offer a full refund for cancellations within 24 hours of booking, as long as the departure is at least 7 days away. This applies to direct bookings with the airline only.

Airline-initiated changes: If the airline significantly alters your flight (different airport, schedule change of more than 3 hours, different destination), you are almost always entitled to a free rebooking or a full refund. If the flight is fully cancelled, the EU Air Passenger Rights Regulation (EC 261/2004) may also entitle you to compensation of up to 600 euros. More on that in our article on flight cancellation rights under EU261.

What does rebooking cost otherwise?

For standard economy tickets, it gets expensive fast. Here is what to expect:

Basic Economy: No changes allowed. Full stop. These tickets are explicitly non-changeable and non-refundable. The only exceptions are the 24-hour rule (for US flights) or an airline-initiated cancellation.

Standard Economy: Rebooking fees typically run between 50 and 150 euros depending on the airline and route. On top of that, you almost always pay the fare difference if the new ticket costs more. If the new flight is cheaper, you usually do not get the difference back.

Tip worth knowing: Sometimes cancelling and rebooking fresh is cheaper than paying the rebooking fee plus the fare difference. Run the numbers before committing. You will usually get the taxes and airport fees back even on non-refundable tickets, which can add up to 20 to 80 euros.

Booking directly with the airline has a practical advantage here. You are the airline’s direct customer and can request changes without going through an intermediary. With OTAs like Expedia or Booking, all change requests go through the platform first, which adds time and can create complications. We cover this in detail in our guide on booking direct vs. using an OTA.

How does rebooking actually work?

The fastest route is almost always the airline’s app or website. Find your booking under “My Trips” or “Manage Booking.” The process:

Open your booking and select “Change flight” or “Rebook”
Search for your preferred new date or route
Review the fees and any fare difference
Confirm and download your new boarding pass

Calling works too, but expect wait times, especially after major disruptions. The app is faster in nearly every case.

One thing worth knowing: your name on the ticket is almost never changeable. You can shift the date, but you cannot transfer the ticket to another person. Name changes are excluded in virtually every airline’s terms and conditions.

When does cancellation make sense?

Cancelling means giving up the flight entirely. You get a refund only in these cases:

Flex fares: Full refund, usually with no time restriction.

Airline cancellation: The airline cancels your flight. In that case, EU261 entitles you to a full refund of the ticket price regardless of your fare type. Check our full EU261 compensation guide for what you are owed.

Travel insurance: If you have trip cancellation coverage and a qualifying reason applies (illness, a family emergency), your insurance covers the loss. Without it, a non-refundable ticket means you lose the full fare. Whether travel insurance is worth it depends on your situation. We break it down in our trip cancellation insurance guide.

Always request a refund of your taxes and airport fees, even on non-refundable tickets. Airlines are required to return these in most cases, and the amount is often higher than people expect.

FAQ: Flight Rebooking and Cancellation

When is rebooking actually free?

With flex fares, within the 24-hour cancellation window for US flights, and when the airline initiates the change or cancels your flight. All other cases typically involve a fee plus any fare difference.

What happens if I just do not show up for my flight?

You lose the ticket. Depending on your fare type, you may still be able to claim a refund of the taxes and fees. Contact the airline before your flight to check your options.

Why can I not change the name on my ticket?

Airline tickets are tied to a specific person for security reasons. Most airlines allow minor corrections (a misspelled letter), but full name transfers are not permitted under any standard conditions.

What are my rights if the airline cancels my flight?

Under EU261, you are entitled to a full refund or alternative routing, plus financial compensation of up to 600 euros depending on the flight distance and the notice given, unless an extraordinary circumstance applies.
