I am a fan of AA's boarding, but today I saw what happens when either selfish or stupid passengers derail the process.
I was about the tenth to board an MD80 today and duly sat in my place. (No overhead locker space needed for me, I had to check my carry on because I had a duty free gift!!) Boarding was taking place by group with the back filling up nicely. Along comes Mr Halfwit who is seated way back, he can see that locker space is filling up where he is sitting so dumps his large carry on and large briefcase in the overhead above row 10, taking up a whole section. He commented to his colleague that he should have thought of this when he first got on the plane and put his luggage in the first available locker. "It's so much easier".
The people in rows 10 and 11 had to find space elsewhere, heading further back down the plane and then having to return to their rows holding up oncoming pax. It was ridiculous, if not quite absolute chaos. It took a full 25 mins to complete boarding. As AA allow 30 mins for boarding I guess this is OK.
Hopefully QF will get their priority boarding right, but there is no accounting for idiots.
