The 777X follows on from the popular but aging 777-300ER, and looks set to become one of the aircraft manufacturer’s key airliners. The 777 has been a big success for Boeing since it began service in 1995, and remains the best selling wide-body aircraft. Now expected to debut in 2025, the airplane’s most striking exterior feature is undoubtedly its folding wingtips – a first for commercial aviation.īut what will it look like from the inside? This month, Boeing proudly showcased a test-version of the 777-9X, one of two 777X variants, at the Farnborough Airshow, a UK-based aviation trade event, providing a hint of what passengers can expect. Described as “the world’s largest and most efficient twin-engine jet,” the Boeing 777X was originally scheduled to enter into service in 2020, but the launch of the jetliner has been beset by delays.
