Don't believe everything you see on APC. The compensation was amended with the new (non concessionary) contract. You should also look into how much your medical would cost at other places etc.
The per diem raises 3 times throughout the life of our cba to $1.90 by the time it expires.
As for year 1 FO rates, that's a concession to let one small group get a 50% raise while everybody else gets QOL only. It's management trying to cheaply attract new hire pilots. So is a bonus for that matter. Compensation should be raised unilaterally - this in term will create a generous compensation package that will attract pilots. It also costs more money than any regional wants to pay. Skywest= no Union. It's why year 1 FO is so high. It's also why the E175 is paid less than the CRJ-900 LMAO
As for pay rates, a good comparison would be Skywest year 4 FO to Compass year 4 CA. Or try Endeavor year 7 FO to Compass year 7 CA (even throw their bonus in and see who's making out better... Hint it's not the FO).
