The problem is not alcohol per se, booze has been served on aircraft from day one. . .The actual problems are;. .1. The total smoking ban on a lot of airlines. 8+ hours on a longhaul is a very long time for the average smoker to go without "lighting up". This has the potential to result in a much reduced stress/anger threshold due to the withdrawal.. .2. The seats are so cheap that basically the riff raff element can fly anywhere these days, and quite frankly they just do not know how to behave themselves under the circumstances!!
