True dat Hawkr. Ts&Cs will only improve when they get really desperate. The IFL owners will eventually have to budge or lose business. Everts has home basing but still has trouble getting crews as the work is tough and you're better off at a regional. I think even Kaliita part duex is trying to make things better.
I love old aircraft but it's the loading and unloading and sitting and long duty days and middle of the night and shiite hotels and quick callouts does nothing for me. Calling in unfit/tired does not work and you'll simply be fired. You are also expected to work your days off.
There are big reasons those aformentioned carriers are constantly looking for crews.
