A woman aboard a United flight from Newark to San Francisco is accusing a United Airlines staff of opening her luggage and peeing in it. Lauren Henry did not notice anything wrong with her luggage until she opened it and saw yellow stains on her clothes. She claims that the yellow stain smells like urine, telling reporters last Feb. 25.

Henry immediately took the yellow-stained bag to San Francisco International Airport and filed a complaint. However, she said that a representative from United Airlines did not believe her story. The representative added that she would follow up Henry's complaint.

Officials of United Airlines told TMZ that they don't believe the woman's story and there was no evidence of urine in her baggage. Nevertheless, the Chicago-based airline paid Henry so that she can buy a new luggage.

Henry added that it took her a few washes to remove the urine stain and smell from her clothes. However, this is not the first urine-related incident in an airline this year.

American Airlines Seat Soaked in Urine

Mike Feinberg revealed that he was sitting in a seat soaked in urine last Jan. 12, 2016. He was in a first class seat aboard an American Airlines flight from St. Louis to Des Moines.

"I turn to the gentleman next to me and I go, 'Is your seat wet?' And he goes, 'No' and I said, 'Mine is.' So, I just kind of reach down between my seat to see what's going on, and I go, 'It's urine,'" Feinberg said.

He immediately called a flight attendant and offered him blankets and a plastic bag to sit on. The attendant explained that there was an older passenger on the previous flight who was having a problem going to the restroom.

"He could have been the nicest guy in the world, but could have Hepatitis B, Hepatitis C, could have had Ebola. I don't know what the guy had. Biohazard is not a privacy issue. It's a policy. It's a procedure," Feinberg added.

At the airport, American offered him a shower and a new pair of pajamas. He also received a compensation of $1,000 and $500 for a new suit. His 10,000 frequent flyer miles were also refunded.

"Our aircraft cleaners are trained to look for visible items like trash left on the seats, floor and seatback pockets. We regret that the cleaners did not detect that this particular seat was wet," a statement from American Airlines said.
