Snoring
Once again my early morning flight was disturbed by the constant loud snoring from the guy in 1A. Other than put on my headphones to hope that even without music, he is drowned out so I can read my briefing for my meeting without gnashing my teeth, what do you do? Kick the seat (only if you are directly behind him), ask the FA to help? Get out of your seat to shake him awake (not a good idea if you are in a window seat).
