While Delta flies domestic flights out of Delta Airlines New York Office Terminals C and D at LGA, it handles the majority of its international traffic out of Terminal 4 at JFK. With significant investments in facility modernization at both airports, Delta has enhanced passenger experiences with updated lounges, expedited check-in procedures, and larger gate spaces. Maintaining Delta's robust presence in the cutthroat New York market is made possible in large part by the New York office. It works in tandem with other departments to guarantee seamless daily operations and assumes a strategic role in managing alliances and business ties for the airline in the area.
