Boeing ( BA ) conducted the first certification flight test for its long-delayed 777-9 plane on Friday under the oversight of the US Federal Aviation Administration, the company said in a post on X Saturday.

Boeing ( BA ) received a type inspection authorization from the FAA, the company confirmed to MT Newswires in an emailed statement. It expects the 777-9 to enter service next year, media outlets reported Monday.
