Now everyone knows how will situation on market look like but one month ago they didn't know this crisis was going to hit that severe.
Truth is that covid 19 caused much bigger impact on aviation industry and tourism in general comparing to any other crisis we had so far but no one can predict how long will it take until next recruitment.
I guess first airlines to start expanding or recruiting will be in Asia, but let's wait and see what will happen.
Anyway, you will always have airlines like Ryanair looking for young and 200h cadet so they can shape him in way they want than someone with 2000-3000h FO who will adopt harder to new procedures and airline policy...
