The world’s largest twin-engined jet, 777X has successfully completed the first test flight.
The flight took off near Seattle and lasted four hours.
Two attempts were called off earlier this week due to high winds, the report added.
Further tests are needed before the aircraft enters service with Emirates next year, the report also stated.
The 252-foot-long passenger jet had been due to launch this year but has been delayed because of some technical difficulties.
The 777X is a larger and more efficient version of Boeing’s successful 777 mini-jumbo.
Standout features include folding wingtips and the world’s largest commercial engines.
Boeing says it has sold 309 of the plane – worth more than $442 million each at list prices.
The plane will go head-to-head with the Airbus A350-1000 which seats about 360 passengers.
