I have never flown in a Europa but I know a man who has built TWO of them and still has the second one. Both are the tricycle undercarriage version. He has been all over in it/them from Tenerife to the Scottish islands. Mostly he flies solo and usually takes a folding bike along.
If you have specific questions I can forward them or ask if he is OK with you contacting him direct.
