Thank you for sharing your insight.
I'm monitoring FR24's statistics webpage closely and it seems that the industry has exceeded those numbers (60-70% of 2019) for the commercial flights (see the second chart).

Yesterday there were 93314 commercial flights tracked compared to 120591 on the same day in 2019, which is approximately 77% of 2019. The difference though is around 27k flights. Will these flights (and therefore jobs) ever exist again?
