The airlines have been forced to apologise after accidentally flying a passenger 3,000 miles in the wrong direction.
Lucie Bahetoukilae, who speaks no English, was intending to catch a plane to Paris and was horrified when she landed in San Francisco.
United Airlines have said sorry for the ‘horrible failure’ to correctly check Ms Bahetoukilae’s boarding pass.
It took Ms Bahetoukilae 28 hours to reach her intended destination after the cock up on April 24.
A United Airlines spokesperson said: ‘We deeply apologise to Ms. Bahetoukilae for this unacceptable experience. When she arrived in San Francisco we ensured she got on the next flight to Paris and refunded her ticket.’
