Leidsin küsimusele sellise vastuse Ryanair'i lehelt :)
CAN I CANCEL MY RESERVATION BEFORE TRAVEL AND DO I NEED TO NOTIFY RYANAIR IF I AM NOT TRAVELLING?
All Ryanair flights are fully changeable but cannot be cancelled. Passengers are therefore not required to notify us if they are unable to travel on their booked flights. Passengers who do not use their outbound flight may use their return flight. Ryanair flight dates/times/routes can be changed up to 4 hours before the flight departure time via the Manage My Booking section of the website. Name changes may be made up to 4 hours before to the outbound flight.
In all cases please note that no changes can be made once a passenger has checked in online.
If you do not use your booked flight the air fare, fees and charges are non-refundable but you may apply in writing within one month of the date of original travel for the refund of the Government Tax paid. Government tax refunds are subject to an administration fee. click here for fee details. If the refund amount is less than the applicable administration fee, no refund will be made.
