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.

After a three hour, 51-minute flight over Washington state, it successfully landed at Seattle's Boeing Field. The first Boeing #777X is in flight. After a few hours of flying, the jet will land at Boeing.

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.

Earlier in the day, Boeing officials said, as quoted by Reuters, that the maiden flight would continue 3-5 hours and then the model would be tested for months before the jetliner enters service with Emirates in 2021.

“To me, this is the flagship for the big airlines around the world ... it represents the great things we can do as a company”, 777X marketing director Wendy Sowers added.

According to information on the company's website, the new Boeing 777X is expected to be the world’s largest and most efficient twin-engine jet, which will deliver 10 percent lower fuel use and emissions and 10 percent lower operating costs than the competition.
