You don't need to do anything - simply fail to turn up at the airport.
Please note that when you book a flight with us, the tickets you buy are always non-refundable. See our Conditions of Carriage for further details.
However, we offer our guests the option of buying cancellation protection at the time of booking, the cost of which can be seen here. Please note that you are unable to add cancellation protection to your booking afterwards.
Do you have cancellation protection and need to cancel your flight with us?
In the event that you purchased the cancellation protection and need to cancel your flight with us, please see WOW air’s Cancellation Protection terms - seen here. Please bear in mind that no refund will be paid unless you purchased the cancellation protection and it applies to the booking in question.
If you decide to cancel your flight with us and you do not have the cancellation protection your flight will not be refunded.
