It's interesting how people are so quick to hijack the words "change" and "normal". The aviation industry is give or take a century old...wtf is "normal"? Low cost aviation has only been around 30 years. Concorde has been and gone in the last 50. Rich folk who own airlines are trying to make some form of space travel "normal". Hell, 40 years ago dolled up stewardesses in miniskirts were totally standard. You get my drift.
Of course commercial aviation will change, it was going to change anyway without Covid19, there are a myriad of factors - some known, some yet to be discovered - driving such change. How Covid19 will speed-up (or slow-down) such changes is yet to seen. Some are obvious in the short to medium term, some are more debatable, but to suggest that everything will swing back to "normal" is not just myopic in terms of Covid 19 - its requires a complete disregard of the history of the industry you all work in.
Change is part of life, and in aviation it has traditionally been swift, dramatic and far-reaching. The fact that airlines (and the support industries) have globally restructured already, entailing the loss of hundreds of thousands of jobs whilst permanently retiring entire fleets of aircraft, is a little bit of a clue. The fact that the virus and all the various economic interventions are still in full swing whilst they speed ahead with these restructuring plans is an even bigger clue.
The aviation industry is continually changing and it will probably change further and faster as a result of Covid19. Whether it is good change or bad change depends entirely on personal circumstance and values. And there is no normal in this industry...there never has been and there never will.
