Boeing has taken one of four test aircraft of the 777-9, the world’s largest twin-engine passenger aircraft, to conduct certification flights with the Federal Aviation Administration (FAA) in Mexico.
The aircraft registered as N779XY landed at Toluca International Airport from Colorado Springs on Friday, August 2, and began test flights the following day.
Located at an altitude of 2,660 meters (8,730 feet), Toluca is one of the airports used to test operations in thin air environments, which make takeoffs and landings longer.

In addition to Toluca, El Alto International Airport in La Paz (Bolivia) is often used for this type of test, but in even more challenging conditions since it is located 4,062 m (13,353 ft) above sea level.
Focus on certification in 2025
After several delays, Boeing has obtained FAA approval to begin certification flights on July 12. It is one of the last steps before the civil aviation authority allows the aircraft to enter service.
Boeing, now with new CEO Kelly Ortberg, who takes office on August 8, expects type certification of the 777-9, the largest variant of the widebody 777X, by the end of 2025.
The first customers to receive the 400-plus-seat aircraft will be Lufthansa, which has 20 orders, and Emirates Airlines, with 170 aircraft under a broader agreement that also includes the 777-8.
