The parent of American Airlines, coming off a $436 million loss in the first quarter, is dropping its lone daily San Francisco-Honolulu flight and taking 188 seats a day out of the Hawaii market in September.

But Hawaiian Airlines said Thursday it will help meet demand by increasing capacity on its own San Francisco-Honolulu flight by 30 seats on Nov. 6 by subbing its 294-seat Airbus A330-200 for its 264-seat Boeing 767-300ER.

AMR Corp. said Thursday it is eliminating its nonstop San Francisco-Honolulu route on Sept. 7 as it attempts to turn around its finances.

"It’s part of our strategy to focus on cornerstone markets — Los Angeles, Dallas/Fort Worth, Chicago, Miami and New York," AMR spokesman Jim Faulkner said.

In April, AMR said it was scaling back plans to add new flights and retiring at least 25 older, gas-guzzling planes amid high fuel prices.

Faulkner said the airline doesn’t break out its load factor, or percentage of seats filled, on specific flights, but added that "if a service doesn’t have a return on it that we like, we would look at redeploying it to another market."

American was using a Boeing 757 on the San Francisco-Honolulu route.

Following the cancellation, American will have 12 flights a day to Hawaii — which include the four major islands — from Los Angeles, Dallas and Chicago.

Delta Air Lines and United Airlines also fly between San Francisco and Honolulu.
