That list brought back memories!!!!
Vanguard (almost went there before Spirit)
Access Air (call sign-"cyclone"?)
Midway (2 and 3) (interviewed when they had the CRJ and 737)
ATA
used to see them all in KLGA "back in the day"

Pro Air out of DET (Detroit City, MI)

I can go on, but I "digest", and I am starting to show my age...
