Efforts finally had some success on April 28, 2006, when ATA Airlines re-established daily non-stop service between Hilo and Oakland International Airport in California aboard its Boeing 737-800 aircraft. ATA Airlines' inauguration of direct overseas service to Hilo for the first time in nearly two decades was met with great fanfare and proved so successful the airline eventually substituted the larger Boeing 757-200 on its flights to Hilo during the peak travelling season around August. Just shy of two years later on April 2, 2008, ATA Airlines ceased operations, citing the cancellation of an agreement by FedEx that provided most of the company's charter flights, and the unprecedented increase in fuel prices. ATA was acquired by U.S. carrier Southwest Airlines, which did not operate any overseas routes at the time. Southwest has now announced their intention to serve Hawaii from California in the future with specific destination information and other details to follow. The demise of ATA Airlines left Hilo without overseas service once again. Meantime, Southwest has since announced its intention to operate flights to Honolulu, Kahului, Kona and Lihue with Hilo not being mentioned in its new service plans for Hawaii.
