Boeing: Dreamliner flights could resume 'within weeks' When all the improvements are in place, tests completed, and approval granted by the US Federal Aviation Administration and other international regulators, operators will be able to resume commercial flights, Boeing said. "As soon as our testing is complete and we obtain regulatory approvals, we will be positioned to help our customers implement these changes and begin the process of getting their 787s back in the air," said Boeing Commercial Airplanes President and CEO Ray Conner. Passengers can be assured that we have completed a thorough review of the battery system and made numerous improvements that we believe will make it a safer, more reliable battery system.
