Boeing has been working on the 777-9x for over 2 years, and it’s getting closer to becoming a reality. It’s expected to begin production in 2017 and in the air by 2020. The Boeing 777-9X is longer than the current 777 and will seat over 400 passengers, with three classes and a range of over 8,000 miles. It’s also going to have wider cabins and larger windows. Sounds VERY cool!
