Already a world wide pilot shortage
The COVID 19 pandemic will just make it worse as those nearing retirement will probably just call it a career (who can afford too) instead of going back to reduced wages and schedules at least until there is a dramatic demand for travel again. Refresh my memory is the mandatory pilot retirement age 62 or 65, I know it was increased from 60 to 62 a few years ago.
Stay Safe,
