I'm not sure about the ExpressJet question of yours, but as for Continental pilots' recommendations:
Nearly every pilot off the street in class at CAL right now has one, according to our sources. CAL's pilots can fill out an online rec for as many pilot friends of theirs that they want, so there are many thousands of apps on file through
www.airlineapps.com that contain an internal CAL pilot's recommendation.
We'll keep you updated as new info comes along.
