Traveling is hard enough when you have to deal with expensive tickets, long security lines, flight cancellations, gate changes, baggage fees, and difficult customs agents. But nothing is quite as bad as being stuck with a terrible seatmate. Whether they encroach on your space or simply won't stop talking, sitting next to an inconsiderate passenger can make an already uncomfortable situation unbearable.
INSIDER browsed Reddit and rounded up stories of some of the worst seatmates of all time. Of course, these are just for fun as we can't independently authenticate these stories.
"I held that pee longer than any human should."

"When I flew from Dubai to England the first time, I couldn't get out of my seat because the woman next to me had her head on her tray table sleeping. I held that pee longer than any human should. I was too polite." - Redditor emhe91
"I was stuck on a 13-hour flight to China next to a guy who had ridiculously gross smelling feet."

"I was stuck on a 13-hour flight to China next to a guy who had ridiculously gross smelling feet. The reason I know this is because into the flight he took off his shoes and socks. I think the smell was worse because there was airplane trouble before the flight took off and we were stuck in the airport on Christmas Eve for about 12 hours before being able to board." - Redditor FifthSurprise
"A little kid threw up on my favorite jacket."

"A little [kid] in the seat in front of me threw up on my favorite jacket and on the laptop of the guy next to me. My jacket was on the floor under his seat and he threw up down the side of his. I was not happy." - Redditor The1RGood
