Devo, you rock in that plane thread.
We've done four round-trip flights with Addie in the last year, and she's been great, but we work our butts off as parents to make sure she is calm and not bothering the people around us. Also helps that my wife is a frequent business flyer, so we're always in Economy Comfort or bumped up to First Class. That extra bit of leg room really helps.
With all that said, parents who don't try to calm down their kids or teach the older ones how to behave on planes drive me nuts just as much as anyone else. I started flying at 6 months old and as I got older, my parents taught me how to behave appropriately. I loved going on plane flights.
