RyanAir extra costs on the Airfare?

You will be charged extra if you take a suit case that is to be checked in. If you check in at the airport you will be charged extra. You will also be charged insurance if you don't opt out, these will be on the options when you book on line, read it all carefully. You can avoid extra cost by checking in on line and printing your own boarding card and only taking hand luggage. You can only book in on line if you take hand luggage. Hope that made sense and was of some help. Make sure you read all the options when booking. Good luck
