It's simply impossible for recruitment to start as early as 2 years from now. You just have to do the maths on the training required for the guys coming back from furlough or unpaid leave. If you want to put a totally realistic date to jobs, go for 2026. If you look back at the 1990's where you had a number of Airlines going bankrupt in the early part of the decade, combined with over recruitment in the 1980's, there was a recruitment hiatus from 1990 to 1996.
Look as well at the recent news on Easyjet. They have deferred delivery of orders that were supposed to be delivered at the beginning of this decade to the end of the decade.
