Last year, Boeing was scheduled to take to the skies with the newest updated version of their Boeing 777 wide-body jet, called the Boeing 777X. However, the aircraft, which was unveiled in a very muted manner due to the media event coming very close after the Boeing 737 MAX grounding, had to push back its schedule of test flights and entry into service due to the issues that were discovered with the GE9X engine which was specifically designed for this aircraft. In the meanwhile, Boeing continued testing of the aircraft on the ground.

Now, Boeing has revealed that the Boeing 777X will be all set to fly for the first time on or after January 23, 2020. Here is the update they published online.

After years of design and testing, it’s almost time to fly. The #777X will make its first flight as early as January 23, subject to weather and other factors.

The first flight will be one of the many flights the aircraft will have to undergo for testing and certification. The test flight will be held on the morning of January 23, from the Everett facility, The Air Current wrote this morning before confirmation came from Boeing. But flight testing, just like rocket launches, is subject to all technical and weather-related criteria being a go, so I won’t be surprised in case they decided to take an extra day on the effort.

Update: Boeing has postponed the First Flight from January 23 to January 24, 2020, on account of the weather. 

We are postponing the #777X first flight that was scheduled to take place tomorrow, Jan. 23, due to weather. The team is currently assessing the possibility of flying on January 24. Stay tuned for updates.

The 777X will be the largest twin-engine passenger jet to be built, which would be able to seat well over 400 passengers for the 777-9 variant.
