You speak the truth my friend lots of time spent and maybe a pet peeve expanded list:
1) crying babies ( understand they are babies its what they do but they are still loud) though noise cancelling headphones help one deal with this.
2) people who don't think showering is a good idea,
3) bladder issue people having to go to the bathroom on a 4 hour flight every 30 minutes,
4) getting crop dusted by individuals several times a flight these people must have eaten like 4 bean and cheese burritos
5) kid behind me kicking my seat and parent oblivious to it, then parent flabbergasted you ask politely if they can see if the kid can stop kicking the seat.
6) people getting upset because I wont exchange my aisle seat for a middle seat so they can sit together.
7) people getting motion sickness next to me, the sweet smell of barf..
8) sitting on a planes in India when it was 120 and they don't turn on the air.
9) Missed connections, trips that should be 5 hours turning into 24
10) Flight attendants who are just tired of their job and let you know. Most flight attendants are great though if you are simply cordial.
When I do retire I am not setting foot on another plane for at least 3 years
