United Airlines 787

FILE – In this Thursday, Jan. 17, 2013 file photo, a United Airlines Boeing 787 is parked at Narita international airport in Narita, east of Tokyo. United Airlines is getting its 787s back in the air. The planes are returning after being grounded for four months by the federal government because of smoldering batteries on 787s owned by other airlines. The incidents included an emergency landing of one plane, and a fire on another. The incidents never caused any serious injuries. But the January grounding embarrassed Boeing, which makes the 787, and disrupted schedules at the eight airlines that were flying the planes. United’s first 787 flight was scheduled for 11 a.m. Monday, May 20, 2013 from Houston to Chicago. (AP Photo/Kyodo News, File) JAPAN OUT, MANDATORY CREDIT
