I've boarded about 8 different planes in the last week and a half, and now we make this thread?
Retroactively Observos: Frontier wasn't bad. Sitting in the bulkhead is overrated (the leg room is nice, but have to keep carry ons overhead).
My AA flight from DFW was a nightmare. Full flight and the lady ahead of me tilts her seat back as far as it goes. Also when the pilot had the "Fasten Seat Belt Light" turned on, there was a glitch and the darn thing cycled on and off about once every 45 seconds. Drove me nuts.
