The decision effectively means Boeing engineers have frozen development work on the ultra-long-range version of the 777X. The Air Current website first reported the delays, saying the 350-seat 777-8 model revised for ultra-long-range flights had originally been scheduled to enter service in 2022 after the arrival of the 777-9 in 2020. This includes our valued customer Qantas.' We continue to engage with our current and potential customers on how we can meet their fleet needs. 'The adjustment reduces risk in our development programme, ensuring a more seamless transition to the 777-8. 'We reviewed our development programme schedule and the needs of our current 777X customers and decided to adjust the schedule,' Boeing spokesman Paul Bergman said by e-mail, adding that the manufacturer remained committed to the 777-8. The Australian airline had hoped for first deliveries of the planes in 2022 and the launch of the world's longest commercial flight in 2023.
