A British businessman trying to get home to Essex somehow ended up in Las Vegas after getting on the wrong flight - despite claiming airline staff checked his boarding pass three times.
Finance broker Samuel Jankowsky, 29, was supposed to be flying to Stansted after meetings in Cologne, Germany.
It was only after an hour-long nap he woke up and spotted the Eurowings aircraft had flown past the UK on the journey-tracker on the entertainment system.
He frantically Whatsapped his pregnant wife, Monique, using the on-board wifi before he landed 8,500 miles away in Las Vegas on June 30.

But he claims when he landed he was treated as 'a common criminal' by US immigration officials who he said threatened to detain him for not having a visa.
He eventually flew back to Cologne - but claims he was banned by Eurowings so had to travel to Stuttgart airport for a flight home.
Samuel from Basildon, Essex, who travelled 17,000 miles - said: 'When I got on the plane I did think it was a big plane for a short flight, but I didn't worry about it.
'I put on my headphones and went to sleep.
'When I woke up I saw that we had passed the UK.
'I asked the person next to me what was going on and he said: "We're flying to Vegas".
'I said: "Oh f***! Can we turn the plane around?" I didn't even know Eurowings flew to Las Vegas,' he added.
The father of Aston, six, and Thalia, one, said adding to his distress was the fact that his wife Monique, 25, was waiting for him in London and was seven months pregnant.
He said: 'I paid 12 euro so I could get wifi and Whatsapp my wife to explain. She was distraught and called Eurowings to complain.'

At McCarran International Airport in Las Vegas, Samuel said he was treated as 'a common criminal' by US immigration officials who threatened to detain him.
He said: 'I was treated like a person who tried to enter the US without a visa.
'The official said we had an hour to do the paperwork to put me on a flight back to Cologne.
'If I missed the flight, I'd be detained until Tuesday when there was another Eurowings flight.
'I had a boarding pass for London Stansted which cost around 120 euro.
