Delta Connection is a brand name for Delta Air Lines, under which a number of individually owned regional airlines primarily operate short- and medium-haul routes. Mainline major air carriers often use regional airlines to operate services via code sharing agreements in order to increase frequencies in addition to serving routes that would not sustain larger aircraft as well as for other competitive or operational reasons.
