I am sure it will bounce back, may take some time and will be leaner and meaner (not that that is good for airline T's and C's sadly). One thing has stood out for me over the last decade or so: unfortunately (or fortunately?) the flying public are a bunch of total hypocrites when it comes to aspirations versus reality. The climate agenda has been climbing the headlines now for many years, and just as rapidly air travel has been expanding with ever greater numbers flying globally. A lot of people seem quite happy with that fact as long as no-one makes too much of a fuss about the contradiction. Even if Europe slows down temporarily, a whole lot of increasingly prosperous countries will be quite happy to take up the slack,
