Don't pull the back of my seat when you want to get up! Don't stand right next to the carousel when collecting your bag - the line is there for a reason! air rage!

Don't talk too loudly or for the entire flight - most people sleep on planes or are trying to do some work. Make sure the volume on your headphones is turned down so that the person next to you can't hear what you're listening to. If you're going to get up out of your seat every five minutes, book an aisle seat. Ask you doctor about calming babies and small children. No one likes a screaming child. And be mindful of what your child is doing. Kicking seats is not cute.

Be careful when putting your seat back if people are eating behind you!

Don't bring two huge bags on board and insist that they are "carry on". Don't smash other passengers' bags when stuffing your bags into the overhead compartments. Don't decide right when you are putting the bags into the overhead compartment that now would be a good time to sort through the bag(s) for that book and snacks and such while folks are waiting to get to their seats. If someone is minding their own business (reading a book, working on a laptop, etc.) don't start talking to them. When the flight attendants tell you to get off your cell phone so they can start the flight, hang up. DO NOT get drunk on the flight.
