Look at Compass. Once the absolute mecca with upgrade times under a year, highest pay (for like a month), crazy growth and guys who could hold lines right out of the school-house; you'd move 10% on the seniority list every month. Now, less than 2 years later, hiring freeze and lost 8% of their fleet. There is NO stability, except for MAYBE Skywest and Horizon. The only thing you should place bets on is attrition, and the house always gets their money on that bet.
