A British Airways flight had to be cancelled after the crew allegedly became extremely drunk on a night out during a stopover at a luxury resort.Flight BA254 had been due to leave Bridgetown, Barbados at 4.25pm local time on Sunday and arrive at London Heathrow at 6.15am on Monday.But instead, the 336 passengers were left stranded in the Caribbean capital after the airline crew were deemed unfit to work due to a night of excessive intoxication. The crew allegedly partied so hard at the AUD$980 per night luxury resort that one hostie was vomiting in the bar, while another male worker collapsed and had to be escorted to his hotel room. News.com.au understands that British Airways has stood a number of flight attendants down while the incident is being investigated.“We expect the highest standards of our crew, and we are urgently investigating this matter,” a spokesperson said. The airline crew members had allegedly been involved in a “vodka and beer session” at a hotel before the scheduled flight, The Sun reported.The incident is said to have taken place at an all-inclusive, oceanfront hotel popular with honeymooners, but the hotel itself has not been named.The publication also reported that furious guests who had saved up for their trip-of-a-lifetime at the holiday destination began filming the group, who slurred back: “We’re British ­Airways crew what of it?”. Approximately 336 passengers on the Boeing 777-200 were left stranded after the sudden cancellation, with no idea why the flight had been axed. “One of the perks of working as flight crew for BA is staying at incredible hotels in far-flung destinations,” one source told the newspaper. “And the team who had flown into Barbados were making the most of their stay at an idyllic retreat where the guests are all made up of honeymooners and families on a trip-of-a-lifetime.“It’s an immense privilege, and it’s understandable that the group wanted to enjoy themselves. “But some of this crew behaved in a manner that did not befit British Airways.“The vodka and beers kept being poured and some of the team were clearly drunk.” The source added: “Guests complained about their behaviour after one stewardess threw up and one of her colleagues collapsed and had to be helped to his room.” Figures published by Eurocontrol suggest that cancelling the flight could have cost British Airways more than £100,000.Such costs are mainly made up of finding hotel accommodation for hundreds of people at short notice, as well as transport to get them to and from the airport.
