Thank you for your message,
Unfortunately the airline does not offer the refund option.
However, due to the exceptional circumstances, they allow you to cancel the booking and keep the ticket open for changes without penalty during one year after the ticket was issued.
Later, you can use this credit to pay for new flights (always with the same airline and for the same passenger) of your choice without penalty, provided you pay the flight fare difference, which necessarily has to be zero or positive and the taxes of the new ticket.
These new flights must take place until one year after your current ticket was issued.
If you wish to proceed with the cancellation and credit creation with 30 EUR service fee per passenger, please confirm the names of the passengers you wish to cancel and create the credit for in your reply, as well as the four last digits of the card used to book these flights.
Waiting for your instructions.
