Gotogate flexible ticket is a scam. I bought flexible ticket after paying 200 EUR for 2 persons. When I rescheduled my flight they again charged me 190 EUR again saying it’s the fare difference. The fare was same per my previous booking as my travel date was 3 months ahead. Not sure how they decided 190 EUR was the fare difference. I used to think one rescheduling was included in flexible ticket. Pay extra but book with Airlines directly.
