WSJ News Exclusive | Boeing’s Delivery of New 787 Dreamliners Likely Delayed Until at Least Late October

Deliveries of Boeing Co. ’s 787 Dreamliner will likely remain halted until at least late October as the plane maker has been unable to persuade air-safety regulators to approve its proposal to inspect the aircraft, people familiar with the matter said.

With almost all deliveries paused for nearly a year, airlines and other Boeing customers increasingly are able to use the delay to walk away from deliveries or negotiate for concessions from the aerospace giant. Deliveries were first halted because the company and the Federal Aviation Administration began taking a deeper look at the plane’s manufacturing defects. The holdup has choked off an important source of cash for Boeing and complicated plans for airlines.
