A pilot shortage only exists for those airlines that are low cost, don't look after their pilots, pay bellow market value and are experiencing loss of sight and direction from their management.
I don't think legacy carriers i.e. Qantas, British Airways, Lufthansa, KLM just to name a few are really screaming for pilots. Easy Jet, Ryanair, Wiz and Emirates just to name a few is a different story.
