Forget Amsterdam/Lelystad for the time being. It's still not sure if the airport will remain at its current location.... And in The Netherlands it can take more than 20 years to have the green light for a runway extension (example: GRQ) which is necessary for Lelystad to be able to accomodate Ryanair and other B737/A320's.
AMS and RTM are too expensive for Ryanair and GRQ is also waiting for a runway extension. So, for the next couple of years Ryanair will only operate to EIN and MST.
