I'm on a plane, and completely floored by the difference in my experience. No seatbelt extender, no sucking it in to try and fasten a tight seatbelt where I hope the stewardess can still see it... just got on and fastened my seatbelt... with plenty of room to spare! My seat is comfortable - no contorting myself to try to angle away from the person next to me (who is my daughter, and has actually spent a fair portion of the trip with her head on my shoulder anyway!) I even used the airplane bathroom without feeling cramped and claustrophobic...
And the best part... My seat tray is down and I can be on my laptop drinking coffee
