PA - Clipper
CP - Empress
BA - Speedbird
CI - Dynasty

Check Wikipedia's list of call signs - there are a number that are different than the name.

A new call sign - other than "US air" or "Cactus" is not a bad idea. A while back there was thread on this topic (that included a number of humorous ideas.)
Does Cuckolded count?
