Boeing’s long-awaited 777X is expected to be a game changer in modern aviation. However, given its continued delays, fleet renewal and expansion plans from many of the world’s largest airlines are heading into a tailspin. The 777X, assembled at the Boeing Everett Factory outside of Seattle, Washington, continues to be tested and has yet to receive Federal Aviation Administration certification. The jet was first launched in 2013, but it only took its first test flight in 2020.
