If it does not matter if and when you arrive you can take the Flixbus. Otherwise not. I had a ticket for 23.30 to Zagreb. At 23.00 I got a text message that the bus could not drive because of technical problems and I was transferred to a bus at 1.10am. The staff refused to say anything and referred me to the passenger rights. The bus to Zagreb drove normally at 23.30 and there was no one else outside of me. Therefore, I assume that you would have to take a biplane because of me and you wanted to save money by rebooking me. In the next two weeks I wrote Flixbus five times until I got an answer. This answer only pointed me out, however, that you could not get refunded with a delay of 120 minutes and you could not cancel it.
