A man woke up while on a trip and found the plane cabin to be dark and empty, and all of the doors were locked.
He was coming from Louisiana to California with a layover in Texas, and he didn't wake up when 3 dozen other passengers got off the plane.
He called his girlfriend to tell her that he was trapped in the plane, and she called the airline and had them to rescue him about 30 minutes later.
He ended up staying in a hotel room, compliments of the airline, before flying to California the next day.
United gave him a $250 voucher, and they're looking into the incident to find out how it could have happened.
