Useful Tips for Inexperienced (and experienced) Airline Passengers
I've flown on commercial airlines hundreds of times.
N00b. This is like a freshman in college trying to pretend he knows it all. This is a simple list you can copy and paste (and it probably was) from anywhere.
I have several THOUSAND trips and nearly 3 MILLION flight miles.
One of these days I will bore everyone with some really USEFUL advice (example: always close/zip up your carry-on, else you will lose things that jump/roll out on takeoff, landing, etc.; get bright colored smaller bags for inside your carry on so you can find them in the dark).
This n00b doesn't know squat.
