Welcome to FlyerTalk.

Not sure how it would be a security lapse unless you think people going to Geneva are, per se, more dangerous than those going to Edinburgh. Think carefully before you answer, because I'm Geneva right now.

Seriously, if you were screened for weapons and explosives, it really doesn't matter, from a security viewpoint, what your boarding pass said. Even if it was a way to get past ID checks (which do not contribute to security anyway), a person with bad intents could hardly rely on getting the wrong boarding pass when they needed it.

I can understand your annoyance over the luggage, though. I've never had compensation where luggage went missing for two days, but you can always try. (I was always just ridiculously happy to get my luggage back!)
