Travel Nightmares: Don't' Get Stuck Next to This Guy

Dec. 22, 2009— -- Millions of travelers are expected to take to the skies this week for Christmas and New Year's vacations. For most, everything will go smoothly.

But for a small group, the trip will turn out to be a nightmare. And it has nothing to do with weather delays or bad airline food.

These few unlucky travelers will have the unfortunate luck of being stuck for hours next to somebody with maybe bad body odor, or somebody who is too fat to fit in their seat or maybe that person who just won't shut up no matter what you do.

Don't Offend the Fat Guy

James Miles, of The Woodlands, Texas, encountered a passenger who might have been better of purchasing two seats on a flight from Newark to Houston.

"A huge fellow pushed his way through everyone and boarded first with the gate agent's approval. Sure enough, when my wife and I got to our assigned seats, there he was, right in 19A with us in 19B and 19C. Needless to say: My wife had no room because his guy had lifted the arm rest and proceeded to encroach into 19B," Miles said.

So what do you in this situation? Miles sought out the flight attendant who asked Miles to be quiet so "I don't offend him."

"After some yelling and several threats the flight attendant started moving people around until she found a small child traveling with his parents to set next to this guy," Miles recalled. "My wife and I were split up and the small boy's parents were also moved to give 'the fat guy' a seat and a half."
