On April 2, 2008, ATA filed for Chapter 11 bankruptcy protection. ATA then announced it was ceasing all services, effective 4:00am EDT, Thursday April 3, 2008, citing the unexpected loss of a major contract for its military charter business, as a subcontractor of FedEx Express, along with recent increases in jet fuel prices. Red-eye flights in the air at the time of the announcement proceeded to their destinations. Flight 4586 from Honolulu to Phoenix was the last ATA flight, departing almost two hours late at 12:10am (HST) arriving April 3, 2008 at 8:48am (MST).
