Schedule adjustments: Airlines shuffle flights By Doug Oakley / May 30, 2001 Share 1 -- HONOLULU -- Air carriers with service to Hawaii are adjusting their schedules to fit changes in the economy, while local players Aloha Airlines and Hawaiian Airlines are starting up new routes. The following is an update on air service to Hawaii:Delta Air Lines dropped its nonstop Dallas-Honolulu service April 1 and turned its Atlanta-Honolulu service into a one-stop via Los Angeles.Northwest Airlines discontinued its San Francisco-Honolulu flight May 1 but will increase service from Minneapolis.The airline's once-daily roundtrip flight from Minneapolis to Honolulu will continue year-round. In the past, that flight had been a winter flight only.United Airlines discontinued its nonstop Chicago-Honolulu flight Feb. 14, but started a new San Francisco-Maui flight Feb. 15.With the changes, United has 19 flights a day to Hawaii, including eight to Honolulu, six to Maui, three to Kona on the Big Island and two to Kauai.United's managing director in Hawaii, Norm Reeder, said air service here likely will decline this year."Seats are going to ratchet down in 2001 due to the economy and the move by the major airlines to newer but smaller aircraft," said Reeder. Airlines that substitute a DC-10 for a 767, for example, can lose up to 40 seats a flight, he explained, while those that substitute a 777 for an older 747 could lose up to 100 seats a flight.United, predicting an increase in travel to Kauai in July and August, also is adding a third weekly flight from San Francisco from the first week in July to early September, Reeder said.Aloha Airlines started service four times a week from Oakland, Calif., to Kona on April 5.On May 1, it started service from Las Vegas to John Wayne Airport in Orange County, Calif., continuing to Honolulu. It will start service from John Wayne to Maui on June 1.The airline already offers service from Honolulu and Maui to Oakland and Las Vegas.All the carrier's new mainland routes use 737 aircraft.Hawaiian Airlines is starting Honolulu-San Diego service June 15 with one roundtrip daily on a DC-10.The airline also recently took delivery of the first of 13 new 717 planes for use on interisland routes. The new planes will replace an aging fleet of DC-9s by the end of the year.At the same time, Hawaiian said it will lease three new 767 jets, starting in October, to replace three of 14 DC-10s used on its mainland routes.A spokesman said Hawaiian plans to replace its entire fleet of DC-10s -- some of which are more than 20 years old -- but the carrier does not yet know when or with what type of aircraft.Hawaiian will take delivery of the three new planes in October, November and December.Continental Airlines increased its Houston-Honolulu service from one daily roundtrip with the addition of a second roundtrip that will fly five days a week through Sept. 5.
