During the delayed flight, you have the option of a different flight, you have the right to request an alternative flight operator to purchase an alternative ticket. This is also possible even if the new flight class exceeds the ticket class you purchased on the delayed flight.
When your flight is delayed, your airline may offer you compensation in the form of flight vouchers. But be careful – in accordance with the legislation, with the passenger voucher you refuse to accept financial compensation in the future.
