Unless they've changed their seat layout or the entire population of the region shrinks by a few inches I have no idea why Qantas belongs on this list.

I'm only 6' and my knees always rub on the seat in front of me on Qantas flights.

Thai, is a fucking dream boat by comparison.

Edit: and yes I've done the MEL-LAX flight on Qantas, knees rubbing the whole time.
