Singapore Airlines (SQ, Singapore Changi) on Sunday October 20, 2013, operated its last Singapore Changi and Los Angeles International direct service using an A340-500. The airline's other ultra long-haul A340-500 route, Singapore Changi to New York Newark, is due to be suspended from November 23, 2013 on. Though the routes have been operational for roughly ten years, rising fuel costs have forced the airline to reconsider their viability. Singapore Airlines has not announced any definitive timetable for the retirement of its fleet of four A340-500s but given their premium configuration, it is expected they will be immediately retired following the end of the Newark service. Emirates (EK, Dubai International) and Thai Airways International (TG, Bangkok Suvarnabhumi) have also moved to gradually retire their respective -500 fleets from revenue service.
