Good evening Knievel!
Yes, Ryanair do charge you to check in at the airport. They have done this for just over a year I think. First of all the charge was £2 then it went up to £4 and now they are charging £5. There is no charge if you choose to check in online and print out your own boarding card. They (like many other airlines) also charge you to put luggage into the hold. If however, you want to take a suitcase then you are unable to check in online and must check in at the airport. So you have the £10 luggage fee plus the £5 airport check in fee. Now I only use Ryanair if I don't have to take a suitcase.
