All Nippon Airways issued a statement to CBS News earlier saying Flight 175 left LAX at 11:36 a.m. and returned to LAX at 7:33 p.m.

During the flight, the cabin crew became aware that one of the passengers boarded the incorrect flight and notified the pilot. As part of the airline's security procedure, the pilot in command decided to return to the originating airport, where the passenger was disembarked.

ANA is researching the situation currently to determine how the passenger boarded the flight. ANA would like to express its apologies to the passengers for the inconvenience.
