Clark told reporters there were no plans for additional orders at the Dubai Airshow after Emirates agreed on Monday to purchase 65 more 777X jets.

Boeing said on Sunday that it would study a potential stretched version of its delayed 777X aircraft.

Clark dismissed speculation that Emirates might order Airbus A350-1000 planes at the show, saying this was never under consideration.

Boeing’s 777 family and Airbus’s A350 series have replaced the industry’s four-engine jumbos.

Airbus failed to secure sales of the A350-1000 to Emirates at the previous Dubai Airshow in 2023, when the airline raised concerns over the maintenance performance of Rolls-Royce’s Trent XWB-97 engine and opted instead for the smaller, more widely used A350-900.

Clark on Tuesday praised the A350-900 as a “peach of an aircraft” and indicated that Emirates would order more of them in time.

Clark also reiterated faith in the 777X despite several development delays. “I still believe the 777X is good to go…It will be right in the end,” he said.

Boeing last month announced another delay and took a US$4.9 billion charge for its largest twin-engined plane, pushing deliveries to 2027, seven years later than originally planned.

Boeing confirmed that it won regulatory approval to proceed to the next and most important phase of certification trials for the 777X.

The U.S. company has been aiming to reset its relations with staff, customers and suppliers after a more than five-year corporate crisis that disrupted production and sent it deeply into debt.
