Funny as hell, people complaining about "seat poachers". Not too many years ago all seats in coach were equal. Now that the airlines are screwing people by charging extra people start to think that should be the case.
In any event, unless you are the one who paid extra and are being denied your seat, who gives a crap?
Also, to note, AS staff tend to not be as Nazi-ish as many other carriers. They tend to actually act human. Go figure...
