I can only speak from what I see and know for sure is happening in UK at present.
Yes many people have this year taken a holiday abroad after almost three years of lockdown or restrictions in destinations elseswhere.
However I doubt that most people, especially pensioners in UK would have the means to take 2-3 holidays a year even in the best of times.
Air travel has increased over the years, if only for the simple reason of increased population and that in some cases, it's cheaper than other forms of travel.

Sorry if my posting on the current situation here in UK conveys doom and gloom, there is always hope that things will get better, unfortunately I can't see that happening anytime soon in UK or for the rest of Europe for that matter, while what's happening in Ukraine continues.
My cup is neither half full or half empty, I see it for what it is 150 mls, ( preferably a 12 yrs old dram.)
