HONOLULU (HawaiiNewsNow) - The easiest way to explain this is to use one airport. So I chose one I know, BWI. Until the early 1970s it was Friendship airport, named after a village no longer there. My dad's parents are buried at an old cemetery on the airport grounds. BWI, now also named for Justice Thurgood Marshall, is Baltimore's only airport. But it is also one of three airports serving Washington D.C.
Reagan National, on the Potomac, doesn't handle long flights. Virginia's Dulles airport is way out to the west. United flies once a week from Dulles to Honolulu.
So D.C. has nonstop service, just not enough to matter. Dulles is convenient to people who work at the Pentagon or the CIA. BWI is convenient to people who work at NSA and the Naval Academy.
Would BWI be great for Hawaiian? Well, Hawaiian codeshare partner JetBlue has little presence there. Southwest has a hub there, 70% of BWI flights. If Hawaiian did well there, United could take some of that business by adding nonstops from Dulles.
