Boeing's 777X program has faced numerous delays, but the first production aircraft has finally taken to the skies.
The 777-9 is designed to reduce jet lag and passenger fatigue with its lower cabin altitude, larger windows, and higher ceilings.
Lufthansa will be the launch customer for the 777X, taking delivery of at least 20 jets.

The new fleet will feature 'throne' seats with extra space and beds up to 220cm long.
The 777-9 is expected to carry approximately 426 passengers, matching the capacity of the 747 while operating with significantly lower costs.
The aircraft features GE9X engines, composite wings, and folding wingtips for maximum efficiency without compromising gate compatibility.

The larger wingspan reduces induced drag, improving every aspect of performance.
The 777-9 is expected to transport more belly cargo than the passenger 747-8 due to its single-deck layout and larger hold dimensions.
Lufthansa's long-haul fleet upgrade will debut on the 777-9, featuring a new brand and Allegris cabin concept.
The successful maiden voyage of the 777-9 marks a significant step forward for Boeing's beleaguered 777X program.
