Today the FAA ordered all U.S. airlines to ground Boeing’s 787 Dreamliner aircraft. That means United Airlines will not be flying any of the six aircraft it took from Boeing between September 22 and December 27 of last year, out of the 51 it has ordered. United is the only U.S. airline that has Dreamliners in service. Delta ordered 18 Dreamliner planes and leasing aircraft companies based in the U.S. have ordered a total of 92 planes on order.

The action comes on the heels of All Nippon Airways grounding all 17 of its Dreamliners after one of the planes was forced to make an emergency landing in western Japan earlier today. Poland’s LOT launched its Dreamliner service between Warsaw and Chicago earlier today. The flight is scheduled to land in Chicago at 7:28pm local time [editor note: it arrived at 7:40pm].
