This is a cushy airline gig. You don't quite make legacy pay, but you also don't work as hard as a legacy pilot.

I compare it to being a lifer at a regional. You make enough pay to make it worthwhile and have a secure job that runs on autopilot. Why mess with a good thing when you'd have to apply and interview at a legacy, then go through training, and start at the bottom (and likely commute for a while). It's going to absolutely destroy a year of your life vs settling for a decent life at Allegiant.
