Andy Cohen was among disgruntled passengers who spent seven hours on a Delta flight only to arrive back at the airport they departed from on Wednesday morning after a traveler broke the plane's toilet, prompting the pilot to inexplicably turn back instead of carrying on half way through the journey.

Delta Flight 412 left New York City at 9.15pm EST and was due to arrive in the south of France at around 10.30am local time (4.15 EST) after seven hours in the air.

Instead, it turned back over the Atlantic 3.5 hours into the flight and arrived back at JFK at 4.51am, 20 minutes later than it would have touched down in France had it carried on.

In total, they spent 7 hours and 31 minutes on a round trip.

The reason, DailyMail.com understands, is that the airline had more staff in the US to make repairs than in France or anywhere else where it may have to outsource or fly in technicians.

Delta said all the toilets were 'inoperative'.

This is the inexplicable flight path of Delta Flight 412 which turned back over the Atlantic half-way through its seven hour flight to Nice on Tuesday night after a passenger 'broke' the toilet

Bravo host Cohen documented the diversion after arriving back in the US.

He took to Instagram and shared videos of himself walking back through the terminal with his best friend Bruce Bozzi.

'We were an hour outside of Europe, somebody pooped or put something down the toilet that didn't go, broke the toilets. Guess where we are? Back at JFK.

'We had a round trip to JFK. I had a full night's sleep, at least,' Cohen said in a selfie video in the early hours.

Determined to find out who was responsible, he pleaded with them to make themselves known in later updates.

The pair then returned to the airport, along with the rest of the plane, on Wednesday afternoon to reboard.

Cohen and Bozzi, whose family owns the Palm restaurants and who is the longtime partner of Carrie Fisher's ex-husband Bryan Lourd, were not the only ones who complained about the fiasco on social media.

Wes Lowenfield, another passenger on the plane, also took to Twitter to complain

The diversion caused a ripple effect in France where passengers hoping to board the plane and take it back to the US arrived at the airport to find there was no aircraft for them

Wes Lowenfield, an NYU graduate student and veteran, took to Twitter to share a photograph of the flight map.

He wrote alongside it sarcastically: 'Have you ever taken a u-turn in the middle of the Atlantic Ocean?

'With Delta you can experience the joys of a 9 hour tour to nowhere and back. And then you get to wait another day to try again!'

The problem caused a ripple effect in Nice where passengers arrived at the airport preparing to board the flight that had just landed to find there was no plane for them.

'Arrived to Nice airport to fly to NY with my wife this morning. Without any prior notification, Dela canceled our flight.

Cohen continued to post after the captain emerged to speak to passengers and apologize

'Need to get to NYC tonight. Delta refused to even assist with rebooking to a different flight,' Ross Bederman said.

Delta has not addressed why the flight returned to the US instead of carrying on to France.

In a statement to DailyMail.com, the airline said: 'Delta apologizes to our customers for the inconvenience after Delta flight 412 to Nice, France returned to John F. Kennedy International Airport after the crew received an indication that the lavatories were inoperative.

'The flight landed without incident and the aircraft proceeded to the gate for maintenance inspection.

'Customers have been re-accommodated on an alternate flight and were offered a gesture of service recovery for the disruption to their travel.'
