United Airlines on Wednesday said it will cancel flight service between Washington and Dubai starting in late January, meaning no U.S. passenger carrier will fly direct to the Gulf states.<br />The move comes after the U.S. government awarded a government contract for travel on the route in 2016 to rival JetBlue Airways Corp and its codeshare partner Emirates, which will operate the Washington-Dubai flights, parent United Continental Holdings Inc said in an Internet posting.<br />United, along with Delta Air Lines Inc and American Airlines Group Inc , have accused Emirates and two other Middle Eastern carriers of receiving subsidies from their governments that let them buy more aircraft and drive down ticket prices.
