You're looking from the pov of the tourism industry (either consumers, in the form of tourists, or from the pov of providers, in the form of tour operators, accommodation hosts and the like), hence the talk about the price curve and the need to adjust it.
I was talking more from an outside perspective, and, more importantly, from the pov of an outside direct influence (via more taxes/charges). I do not think air-fuel costs are going to get cheaper again, to the contrary, I think the externalities of airplane flight will start being included more and more into the final price. The same goes for accommodation prices, which are dependent on energy prices (you need gas/electricity to keep a room at reasonable temperatures during the summer and in winter). Those are not going back to cheaper prices, either. And there are all the other related prices, for example car rental prices have also increased dramatically and will most probably remain that way, there's no IC cars replacing the current fleets in the near future (for the simple reason that they won't make them anymore) and we won't build enough EVs at reasonable costs to keep the current car rental market exactly as it is (or as it used to be until very recent, that is).
As for the "unmet demand", too bad for the consumers (i.e. potential tourists). The same way the mass tourism industry was invented in the 1930s (give or take), the same way it can be scaled back "societally", by saying things like "if you still want to be a tourist you will do great harm to the ecosystem shared by all of us" (which is most probably true) and similar stuff. No (service) industry has to live forever.
