That was an assumption when an Airline went bust, not a whole Industry. Customer Service roles are indeed transferable but probably three of them equals one Pilot.
If Easyjet reduce their fleet the 'easy' option is to reduce the manpower per aircraft. Come 2023 or whenever the Industry recovers then their will be Pilots and Engineers still out there.
I sincerely hope I'm wrong and my thoughts are with all Airline Staff particularly those where the Mgmt are going after T+C also
