Hawaiian Airlines
In 1966, Hawaiian added all-jet aircraft, the McDonnell Douglas DC-9. Flying time between islands was reduced to 20–30 minutes. In 2002-03, Hawaiian replaced its planes with better ones.  The new planes used less fuel to fly the same distances.  It also changed the design on the tails of its planes.  The airline also started flying to more locations. Today it flies approximately 212 flights a day.
