Unless a significant proportion of the population decides that it is a necessary evil - for example like taxation:Their logic is shite.
Nobody is ever going to get elected on the basis of limiting us on flights. And if some Government just implement it then the opposition will campaign on reversing it and get elected.
Its as simple as that. Cheap flights are here to stay. Anybody who trys and fucks with that is on an electoral hiding.
Noone likes paying taxes, but people understand that you need to pay taxes in order to have, for example, the NHS and avoid horrible things (eg dying early from disease etc).
Maybe soon, although noone will like limiting air travel (and other energy use) people will understand that you need to limit things to avoid horrible things (eg disasterous climate change etc).
There might be different ways of limiting air travel: making it expensive is one way, but another way for example would be to give everyone an equal "air miles allowance" (eg a ration or quota). People who wanted to go over their quota would have to buy the extra from people who haven't used theirs.
This would mean that poor people would either still be able to travel (and very poor people would be able to cash in their air miles), whereas companies and richer people would have to pay a lot more for their 'frequent flier' habits (or maybe they simply wouldn't be able to get hold of any extra air miles above their "basic quota").
