Over the years, many airlines have served this route. The following come to mind:
Eastern (Shuttle and mainline)
Pan Am (Shuttle and mainline)
American (pseudo-shuttle and mainline)
Delta (Shuttle and mainline)
Braniff II (daily)
New York Air (shuttle)
Of these, which did you/ do you enjoy the most?
My favorite was always New York Air. Their "flying nosh" sealed the deal for me!
