In 2008 Oakland saw a series of cutbacks due to high fuel costs and airline bankruptcies, more than other Bay Area airports. In just a few days, Oakland's numerous non-stops to Hawaii were eliminated following the liquidation of ATA Airlines and Aloha Airlines, although Hawaiian Airlines started a daily flight to Honolulu a month later. Skybus Airlines stopped flying to Columbus, OH when it ended operations on April 5. American Airlines and Continental Airlines both dropped Oakland on September 3, United Airlines ended service to Los Angeles on November 2, and TACA ended service to San Salvador on September 1.
