SAN FRANCISCO / SINGAPORE (Reuters) – Boeing Co ( BA.N ) has pushed back the accession of an ultra-long reach of the impending 777X widebody, the US planner said on Wednesday, the latest fallout from an ongoing crisis around its 737 MAX jet.

The delay Longer range 777-8 will inhibit Boeing's ability to acquire an aircraft in line with Qantas Airways Ltd's ( QAN.AX ) plan for 21-hour nonstop Sydney-London flights.
The Australian airline had hoped for first deliveries of the aircraft in 2022 and the launch of the world's longest commercial flight in 2023.
"We considered the plan for the development program and the needs of our current 777X customers and decided to adjust the schedule," Boeing spokesman Paul Bergman said by email, adding that the manufacturer remained committed to 777-8.
“The adjustment reduces the risk in our development program and ensures a more seamless transition to 777-8. We continue to work with our current and potential customers on how to meet their fleet needs. This includes our valued customers Qantas. "
The Air Current website first reported the delays, saying that the 350-seat 777-8 model, which was revised for ultra-long-haul aircraft, was originally scheduled to go into service in 2022 after the arrival of 777-9 in 2020.  The decision effectively means that Boeing engineers have frozen development work on the ultra-long version of the 777X. The schedule delay could put competition at risk with the European arch rival Airbus SE ( AIR.PA ) for part of the ultra-long distance travel market.
Airbus, which offers an ultra-long version of the A350-1000, and Boeing has already sent its "best and final" offers to Qantas for aircraft capable of operating Sydney-London 17,000 km (10,560 miles), one said spokesman for Qantas.
"We still expect to make a decision by the end of this calendar year," he said.
Boee's proposal included a "compelling alternative" to deal with the 777-8 delay because it was keen to stay in the race, according to a source with knowledge of the case who was not authorized to speak publicly.
A spokesman for Airbus said the details of the discussions with Qantas remained confidential, but the A350 was a "perfect solution" to meet the airline's needs.
