Mexico's largest airline Aeromexico said on Monday it had agreed an order for 60 Boeing 737 MAX aircraft, with an option for 30 more, as part of plan to overhaul its fleet and use more fuel-efficient planes.
The order value is about USD$9 billion at published list prices.
The company also said it expects to finalize an agreement to purchase 787-9 Dreamliners in the coming weeks. It said in July it would order 10 787s.
Aeromexico, which went public last year, is betting that Mexico's economy will remain robust in the coming years and analysts have said the order should help them roll out new routes.
It had a fleet of 110 planes as of July.
Aeromexico's operations got a big boost following the 2010 demise of debt-laden rival Mexicana.
