AIRLINE: Hello. At one time, 'regional carrier' used to be synonomus with a small commuter airline using small two engine aircraft that seldom left the area of the country they operated in. But I'm wondering that by today's standard's if Pan Am v3 could be considered a regional carrier? How about Comair, which just seems to go everywhere for Delta? Atlantic Coast Airlines? Bering Air? Boston-Maine Airways, etc? Thanks, Mike Burris Cambridge, Mass
