I had only the worst experience with this airline. First, my flight was delayed overnight due to technical reasons (as announced at the airport), but when repeatedly applying for the compensation on their website, no-one reacted. Second, my flight was cancelled and I was offered a voucher instead. The voucher was supposed to be valid for a year for all their flights, after this year, I could receive money back if I did not use the voucher. I did not use the voucher, so in a year, I asked for money back. They told me that the rules changed, and I could only use the voucher within the next 6 months for another flight. I booked a flight, the flight was cancelled, no other flight could be booked before the voucher expiration date, and I never got the money back.
