Pilots. It's been some time since I read about it. I read some of the small puddle jumper pilots make so little they qualify for SNAP. Sure flying the big boys makes a bunch of money though.
This has changed quite a lot. Starting pay at regional airlines varies, but it is close to $100,000/year now.
This all happened right after the pandemic. Airlines did a lot of early retirements because nobody knew how long the industry would be in the dumps. As it turns out, there was a ton of pent up travel demand, so not only did airlines have to attract people to replace the retired pilots, but also for growth.
You're right, though. It used to be closer to $20,000/year back in 2005, and only went up slightly over the 15 year period leading up to the pandemic.
