Compass is probably your best bet at a fast 175 upgrade.. but it has a risk of them loosing some flying at it’s contract end, this fall.. Horizon would have been a good bet last Fall. Not now, That ship sailed.. Republic.. ya. Maybe a 2-3 year upgrade but 1 year wait for class. SkyWest under 1 year upgrade in the CRJ. But 3-4 for the ERJ.. Envoy??... probably not... Mesa? well Mesa, XJT. 175 will be super senior..So No. Good luck.... amazes me how people demand equipment.. (no offense) but ya. In my day (90’s) you would kill to not have to pay for your training and fly a Saab or E120. And not have to fly the B1900 or J32!!!
