CHICAGO (AP) -- United Airlines says it will fly its new Boeing 787s from Denver to Tokyo starting in March 2013.
The Denver flights that went on sale on Tuesday are the first 787 tickets to be offered by a U.S. airline. Boeing delivered the first 787 to Japan's All Nippon Airways late last year, three years late.
The Denver flights start March 31. It's not certain whether those will be the first 787 flights on a U.S. airline, because United could still add another route between now and then.
Airlines have been eager for the fuel-efficient, midsized plane. Continental Airlines was originally going to be the first U.S. airline to fly it. Continental and United merged in 2010 to form United Continental Holdings Inc.
