I'm not sure who is rubbing it in your face from SkyWest but they are in serious need of a reality check if they really think that way. I always hear about SkyWest pilots taunting other places and it peeves me off, if I hear it first hand I will tell them they are no better, four stripes or three stripes I could care less. That mentality is what starts beef between companies, which is elementary recess mind set in my opinion.
Yes, you are correct NW base upgrades are no where near a 10 month upgrade or even near a 2 year upgrade at OO for that matter. For now anyways... We are losing a TON of pilots every month so it could be very dynamic, however most captains I've flown with since being at SW are lifers on the ERJ side...
