All Nippon Airways (ANA) flight from Los Angeles (United States) to Tokyo (Japan) was returned to originating airport after a passenger mix-up was discovered mid-flight on December 27, 2017.

All Nippon Airways confirmed to CBS News that the flight 175, which took off from Los Angeles Airport at 11:36 am, returned at 7:33 pm to the originating airport after a passenger who boarded the incorrect flight was discovered onboard. ANA claims the situation is being “researched” in order to find out how that happened.

The airline also issued an apology via social media, stating that “we failed to deliver the customer service we strive for. Thank you all for your comments and allowing us to connect, learn and serve you better. We welcome ongoing feedback to understand how we can work to make this right,” presumably making a reference to the outrage on social media after a celebrity onboard live-tweeted the experience.

Model Chritine Teigen posted a series of Twitter updates describing the flight.  For instance, one of the posts read: “They keep saying the person had a United ticket. We are on ANA. So basically the boarding pass scanner is just a beedoop machine that makes beedoop noises that register to nowhere”.
