Stung again: On United jet, scorpion falls from luggage bin into passenger's hair

Attention, United Airlines passengers: Don't forget to lather up with "Off."

A couple returning from vacation in Mexico apparently brought on an unexpected passenger: a scorpion. It turned out to be another stinging moment in a tough week for the airline, according to a report by CNBC.

During a flight from Houston to Calgary, the creature dropped from the overhead bin, landing in the man's hair, according to news reports. When he shook it out onto his tray table and picked it up, it stung him.

The scorpion was disposed of in the toilet. And other than suffering what "felt like a wasp sting," the man was okay.

"Medical personnel met the aircraft after it arrived in Calgary," United spokesman Charles Hobart told CNBC.

"Talk about snakebit," said Andrew Gilman, a crisis management expert. "The next time United does its emergency protocols, they will be dropping insect repellant along with the mask."
