Effective March 26, Delta will add five new daily round-trip flights between Miami and Orlando; four new daily round-trip flights between Miami and Jacksonville; and five new daily round-trip flights between Miami and Tampa/St. Petersburg. The flights will be timed to facilitate new connections to trans-Atlantic flights from Miami. In addition to the new service to London-Heathrow, Delta's joint venture partners Air France-KLM and Alitalia offer nonstop flights from Miami to their hubs in Paris-Charles de Gaulle, Amsterdam, Milan and Rome.

The intra-Florida flights will be operated by Delta Connection carriers Comair and Pinnacle airlines using 50-seat Bombardier CRJ200 regional jets.
