It´s the first international trip for the 737 MAX flight-test fleet.
The airport´s 13,300-foot (4,050-meter) altitude tested the MAX´s capability to take off and land at high altitudes, which can affect overall airplane performance.
Flight testing for the 737 MAX is on schedule with three test airplanes having completed more than 100 flights combined. The fourth and final test airplane will make its first flight in the coming weeks. The program remains on track for first delivery in the third quarter of 2017.
