Until when can I make changes or cancel my flight with a Flex ticket?
Flex ticket type allows ticket changes and flight cancellations. Whenever changing your ticket, a possible fare difference is collected.
You can change your ticket and cancel your flight without a penalty until the check-in for your first flight closes. Or, if you have already taken the first flight in the booking, you are usually allowed to make changes to the rest of the flights until the check-in for those flights closes. See the check-in times.
The conditions for certain routes may allow more flexible timelines for ticket changes and flight cancellations. You can check the full ticket rules in the Review purchase step when booking your flights.
The conditions for certain routes have restrictions on refunds in case you cancel the flight after the first flight is already used.
