Most drunken mob I've ever seen on an aircraft was back in good old Air UK days (sadly missed) - a BAe 146 ABZ-AMS... Bunch of flight attendants in civvies on a training jolly? to AMS took out the last two rows at the back, (handy for the Galley) and were on the Bucks Fizz from when the wheels went clunk... They'd obviously been giving it large in the bar and simply continued on the a/c. Extreme hilarity fuelled by continuous supply ensued, and the on-duty cabin crew simply added to the party. Bad news - shocking turbulence into AMS for the last 20 mins of the flight - excellent... They may well have drunk the bar out of Bucks Fizz, but they also managed to fill most of the honk-bags on board...
