WASHINGTON, (Reuters) – Boeing (NYSE:) Co has announced that it will delay the 777X program by one more time. This was reported Friday by the Air Current aviation industry publication.

According to the Air Current, the U.S planemaker plans to postpone the certification target to late 2024 or for wide-body aircraft by nine to twelve months.
