Dec. 28 (UPI) -- Two brothers may face federal criminal charges for reportedly boarding a Tokyo-bound flight with one ticket, which diverted the trip back to Los Angeles and created a hectic situation in the sky that model Chrissy Teigen documented on Twitter.
Authorities say two brothers with similar names cleared security at the Los Angeles International Airport on Tuesday, holding tickets for separate Tokyo-bound flights on planes from All Nippon Airways and United Airlines.
The brothers used one of those passes, possibly with a duplicate, to both get on the ANA flight.
FBI agents told ABC News they can't yet arrest either of the brothers and are instead assessing their intent.
The accused stowaway brother could face a maximum of five years in prison.
ANA released a statement, noting they were trying to "determine how the passenger boarded the flight."
"During the flight, the cabin crew became aware that one of the passengers boarded the incorrect flight and notified the pilot," ANA said in a statement. "As part of the airline's security procedure, the pilot in command decided to return to the originating airport, where the passenger was disembarked."
About four hours into the flight, the crew learned of the brothers' presence and steered the flight back to Los Angeles
Passengers on the plane, among them Teigen and her husband John Legend, weren't pleased with the decision to turn back to California.
"You can't make up a day. There's no compensation that gives us back that day," Devin McIntyre, a newlywed vacationing on his honeymoon, told ABC News. "And then the feeling of turning around in the middle of a flight doesn't make sense. We tried to get the rationale on that decision, but nobody would give it to us."
Teigen live-tweeted throughout the eight-hour ride.
ANA tweeted out an apology to the passengers of the flight saying they "failed to deliver the customer service" they strive for.
