These five inconvenient fees are nothing compared to folks like Ryanair in the UK and Ireland flying to Europe. They are rock-bottom discounters who grab any fee they can, kinda like Spirit, but Irish style. Ryanair has contemplated a fee to use the restrooms. Ouch! It's a good thing most of their flights are short ones. They already charge you €5 to check-in online and there is a €40 fee if you do not print out your boarding pass and bring it with you.
