I guess with age we see people acting diffently but I know few people, aside from Emigrants returning home for family events or people celebrating an Anniversary / Big Birthday who would have a weekend away 20 years ago that involved flying.
I think I know few who have not had at least 1 a year (some 1 every month or two) over last 5 years. I know my kids are relatively young but their flights are into 3 figures, least eldest one is.
I don't think its movement of money from one holiday destination to another more like a decision that instead of having a nice meal out every weekend we save it up and a little bit more to have a weekend away given that a night out in London with a show and dinner leaves people with bugger all change from £200.
Some destinations will work, some won't but regions who see the potential and invest to grow the initial inflow will do ok in the longer term.
