#REVOLVEawards - ArrivalsTravel around the holidays is always harder, but Chrissy Teigen and husband John Legend had a particularly brutal experience on Tuesday. Fans got to hear all about it, because the model-slash-TV personality live-tweeted their misadventure.

It all started on Dec. 26, when Teigen and Legend boarded an All Nippon Airways flight to Tokyo from Los Angeles. At first, the "Lip Sync Battle" co-host was silent on Twitter, but several hours into the flight, she shared that their trip was off to a pretty horrible start. Namely, they were turning and going back to LAX after having already flown for four hours.

"A flying first for me: 4 hours into an 11 hour flight and we are turning around because we have a passenger who isn't supposed to be on this plane," she wrote. "Why...why do we all gotta go back, I do not know."

Teigen's followers had questions, too, but the model admitted she had "no answers." All she knew was that the person had somehow boarded the flight with a United ticket, leading her to joke that boarding pass scanners must actually "a beedoop machine that makes beedoop noises that register to nowhere."

The trouble didn't end back on the ground, though. After reaching LAX eight hours and 20 minutes after leaving, Teigen said police started interviewing people seated around "the mystery person."

Hours and hours after their original departure, Teigen and Legend eventually made it to Tokyo, landing on Legend's birthday. Unfortunately, the mystery of why they had to go back to drop off the person with the United ticket remained a mystery to Teigen. She did, however, have nice things to say about the airline's employees.

We can empathize with anyone who has to fly eight hours to get nowhere -- especially someone who is pregnant and has to then get on an 11-hour flight -- but let's be honest, at least Teigen can afford to fly so in first class.
