Holidaymakers were subjected to a three-hour flight delay after a rowdy stag party had to be kicked off a flight for 'disruptive' behaviour.
Travellers heading to Bulgaria were left fuming as the party refused to leave the plane leading to a long delay over a mistaken head count.
The drunken stag do were allegedly swearing and wolf-whistling at the cabin crew when they were denied alcohol service.

Five members of the group, including one dressed as a pilot, agreed to get off the Tui plane but two refused to move and allegedly began "squaring up" to the security staff, reports Wales Online.
Holidaymakers shouted “throw them off” before one member of the party allegedly threatened security and said he used to be in the armed forces and knew how to operate a gun.
The rowdy group eventually disembarked the flight from Cardiff but a mistaken headcount when they left led to a delay as passengers had to disembark and re-board.
One passenger said: “Tui should not have let them on board the flight in the first place.
“We heard the group in the terminal an hour before the flight and they were being extremely noisy. I was dreading getting on the plane to be honest.
“There were seven of them, and the groom was dressed as a pilot. It was very unnerving, especially for the passengers in the rows around them.
"I want to highlight the consequences of drinking too much before a flight on the other passengers and also the stag party who never made it to Bulgaria. Incidentally I heard them say they were staying in Sunny Beach. We were thankful [they didn't make it to Sunny Beach] because we were booked in at the old town.
"Surely there is a duty of care in the airport bar when people are obviously flying and they keep serving them alcohol. It makes you think."
Another passenger added: “The stewardess told them as they boarded that they would not be served any alcohol during the flight and it didn’t go down well. They were noisy and used the F word continuously. Some passengers told them to curb their language but they just carried on.
“Another stewardess then approached them to warn them over their behaviour and they cheered her loudly and wolf-whistled her. They were making remarks to other female passengers too.”
The pilot told the cabin crew he would not fly the plane while the stag do was onboard and asked for security to escort them off.
The passenger continued: “One of the men then said he was in the forces and had used a gun before. Eventually, they did walk off while swearing loudly.”
A headcount was then taken by staff but the numbers didn't match on the paperwork.
One passenger recalled: “After the stag incident we were all asked by Tui to give our names to the rep who came on to the plane to check the passenger list. We were then asked to disembark with our bags as they thought there was one passenger too many on the plane. We eventually left at 4.30pm.”
A spokeswoman for Tui said: "We would like to apologise to customers on board flight TOM6412 from Cardiff to Bulgaria yesterday for the delay in taking off. We can confirm that the flight was delayed due to disruptive passengers on board the flight.
"The safety and security of our customers and crew is always our highest priority, and we have a zero-tolerance policy to disruptive behaviour on our flights. The customers involved were offloaded and the flight was able to continue its journey."
