Was on a Jet2 from Glasgow 3 years ago. Early Monday morning flight. I was having a bit of breakfast and the usual Pre-holiday flight couple of pints in the bar after check-in and there was a group being a bit loud, not out of order, just loud. But got louder. Police followed them all the way to the gate, but they did get to board after a discussion. Once on the plane, they got a couple of warnings from the stewardess and the pilot came out and had a word with them too. Most of them calmed down. Plane eventually moved away and got to the end of the runway. There was one guy still playing up, swore at the stewardess, got told if he swore again, he'd be off. Guess what. Yip, at the end of the runway, engines revving up, and back to the terminal. Police on, one guy off, rest of them really well behaved after that, with lots of apologies to the stewardess. Made us all a few hours late getting there.
Once we did take off, Jet2 happy to sell as much booze as possible, announcing special offers, telling people to get plenty for the flight as the trolley is only passing once, etc. I was taking it easy, 4 miniatures did me on that flight.
Same as everyone else has said about this, people having fun is great, and no doubt the start of a trip to Ibiza gets you excited, but if youre having a booze before you're flight, make sure you can handle it and can keep quiet when you need too. Doesn't really matter if families and pensioners or not, people should know how to behave themselves. Unfortunately not everyone can and when they think they are being funny, everyone just thinks they are being a dick.
