Aeromexico has committed to buying 100 single- and twin-aisle Boeing airplanes—a combination of 737 Maxs and 787 Dreamliners—in an agreement that will fuel the airline’s expansion beyond the end of the decade, the Chicago-based airframe maker announced today. The commitment by Mexico’s largest airline includes a mix of ninety 737 Max 8s and 9s, as well as ten 787 Dreamliners, seven of which it expects to take over the next three years. Based on list prices, the value of the order would total $10.8 billion.

“This order represents the largest investment program for a domestic airline in Mexican commercial aviation history and a major step forward in consolidating Grupo Aeromexico’s international leadership position," said Grupo Aeromexico chief executive officer Andres Conesa. “We are announcing our medium- and long-term fleet plan supported by our partners, Boeing and General Electric, that will allow us to maintain a flexible structure to grow according to market conditions.”

The contract calls for General Electric GEnx engines to power the 787s. Boeing offers only the CFM Leap-1B for the 737 Max.

Aeromexico’s entire mainline fleet consists of Boeings, ranging in size from 737-800s to 777-300ERs.  Grupo Aeromexico, the parent company of Aeromexico, uses Mexico City International Airport as its main hub. Last year the group transported more than 14 million passengers and offered close to 600 daily flights to different cities in Mexico, the U.S., Canada, Central and South America, Europe and Asia.
