Atlantic Southeast Airlines is the name of the company (Incorporated March 12, 1979). ASA is just an abbreviation, although, oddly enough, the founder's name was Asa Candler. I'm not sure, but I would think their paychecks and other docs have always said Atlantic Southeast Airlines. I think "Candler" was a better call sign than "Acey", but maybe something like "SkySouth" would be more appropriate nowadays

Anyone know any cool call signs (civilian)? I always liked "Rattler" (Airnow), and I still say bring back the "Critter" call sign (Valujet)...much cooler than "Citrus"
