Boeing Tells Airlines That Dreamliner Deliveries Could Slip

Boeing Co. has told airlines expecting to receive new 787 Dreamliners in coming months that deliveries may be delayed as regulators investigate overheating batteries that prompted the model’s grounding worldwide.

U.K. tour operator Thomson Airways said it’s arranging to use other planes to serve Florida and Mexico if its first 787 is delayed beyond March. Norwegian Air Shuttle AS said the handover of an initial 787 in April may slide and that a second due in June may also be affected.
