The decision to hit reset on the plane and its 226 passengers was due to an "administrative error," an airline source told CNN. (That's airline parlance for "we screwed up big time, everybody.")
The airline further explained the mishap in a statement:
"The cabin crew notified the pilot that one of the passengers boarded the incorrect flight, and the pilot in command made the decision to return to the originating airport."
The snafu was chronicled on Twitter by supermodel Chrissy Teigen, who was onboard the flight with her husband, R&B superstar John Legend. Luckily for people not on the flight, sitting in front of the hypnotic glow of their Twitter feeds, Teigen made light of the stupidly annoying situation by tweeting about it to her 9 million followers.
