I think there’s a fair few who won’t make it onto the flight.I think you're dead right about not everyone making it to the ground. Aside from the covid testing I've seen enough pissed up and incapacitated blues on euro trips - throwing up in bars in lokeren, asleep in the ground in Hamburg and the embarrassing coked up fancy dress blues brothers in Groclin. I doubt you're serious but I also doubt you'd get in like that.
test delays or general confusion.
