“The certification flight testing will continue validating the airplane’s safety, reliability, and performance,” a Boeing spokesperson told Business Insider. “We appreciate our regulator’s rigorous oversight.”
Boeing expects the plane to enter service in 2025, but two major customers have said they expect more delays, possibly to 2026.
The delays have caused problems for aircraft operators because they’re still flying older, less efficient planes as they wait for the 777X.
Airlines are eager to replace aging, old-generation widebodies. The 777X, which competes with the rival Airbus A350, boasts an increased range, capacity, and efficiency compared to its predecessors.
The jet’s immense size — particularly its wider frame — is one of its best-selling characteristics gives operators some wiggle room regarding the cabin layout.
In July, Boeing showed what passengers can expect onboard, from bigger windows and cabins to mood lighting that resembles the northern lights.
