People like it , because , its FREE!
Plus with the added glamour element of flying, people think they can let their hair down and feel good about the whole thing, plus the proximity to all these total strangers !
This comes at a price though..........
A) A miniature bottle drunk at say 35,000 feet is equivalent to 4 drinks on the ground.... because of less oxygen and they are all doubles believe it or not.
B) You get dehydrated VERY quickly ,as cabin humidity is very low, so hello jack daniels, and hello megahangover, unsociable behaviour and DVT
C ) Ok, DVT
is bad enough, but unruly ,agressive and dangerous behaviour involves everyone
The average person drinking say, 5 whiskies on a flight (with the 4x factor in mind) is actually drinking alot more than that.
Factor in less Oxygen,small meals,tiredness etc and things can get pretty bad...
I think i am right in saying that all airlines have a zero tolerance attitude towards drunken behaviour nowadays . . certainly at BA
It will not be tolerated fullstop, and you face either being offloaded, warned , banned (for v long periods) or restrained and arrested / jailed , so be on your guard !
Sit back , relax ,enjoy a drink or two , but maybe just leave it there , drink lots of water , and hey you'll feel great on arrival too!
