From my experience (9 years) in aviation, people seem to fly off the handle into a rage about the smallest things when they are traveling by air much more than they do on any other form of transport.
Example in the UK we have a third world rail system where trains are always late or overcrowded, but people just accept this and get on with it, sure they may be annoyed but they still accept it. But when they fly, even the slightest little thing is enough to send sparks flying. I mean if someone gets on a bus and all the window seats are taken, would they then start screaming and shouting at the driver - Don't think so, but that happens EVERY day in aviation, or if you get to the bus stop late the bus would just leave without you, but you wouldn't then launch into a verbal and sometimes physical attack over it like people do when they turn up late for flights.
I did see a program on TV about this, and it basically said that it's because when people are flying there are a lot of people who are actually really scared of it, but they don't want to show it so become overly aggressive, or people find it hard to hand over control of their lives to someone else and having absolutely no say in the matter, which is basically what they are doing when traveling by air, as on the bus they can just get off, but that's not possible on an a/c at FL300.
Some people are just downright bonkers and unreasonable tho and just complain for the sake of it, or because they think they will get some kind of freebie out of it like an u/g.
I just think that there is a box outside every airport that is only visible to passengers. The box is marked ' Leave Brain Here '. They then remove their brains before walking through the door to the airport, and collect a new one on arrival at the destination.
