Y\Hola from Wisconsin,
Yes you get charged a lot for not having a boarding pass printed out in advance. And they suggest you print in on size A paper. That is a bit different than our letter sized paper. But they let us through.
Checking your luggage, and here is why you should use a different airline. Your luggage cost will be about the cost of your human ticket. I think we got human tickets at 17Euro each and we were charged 25 for each checked piece of luggage.
It was an entertaining experience. They spent more time selling raffle tickets and duty free junk and sandwiches than anything else. Your flight instructions are taped to the back of the seat in front of you. Kind of a "Your safety is your responsibility".
