When I instructed at Gillespie (SEE) Qualcom ran a Global Express from there. Parked it at Royal Jet. There was a Falcon 50 over there too, not sure who it belonged to. Then there's Jimsair at SAN, they do charter and have quite a few a/c. Palomar (CRQ) has a few corp/charter outfits, Jetsource I believe is the biggest and the only one I can recall off the top of my head.
