If you cancel your ticket more than 24 hours after booking, a fee will be charged as a service fee.
Eurowings Airlines Cancellation Policy says Flex ticket flyers make it easy to cancel tickets up to 40 minutes before departure.
In some cases, the cancellation fee may equal the ticket price.
There is no undo function in the long position. However, it may be possible for the passenger to reorganize the flight for an additional fee.
