The tentative order is valued at roughly $11 billion based on aircraft list prices, though jet makers discount heavily for large orders. Boeing said in a statement that it looks forward to finalizing Aeromexico's order commitment.
Mexico City-based Grupo Aeromexico said the order is for 90 Boeing 737 MAX jets and 10 787-9 aircraft.
“This investment demonstrates the commitment Grupo Aeromexico shareholders have pledged to the country and its confidence in Mexico's macroeconomic environment and future,” Jose Luis Barraza, chairman of the Group's board of directors, said in a statement.
The airline said the order is the largest investment in Aeromexico's history. Deliveries of the 787-9s will begin next summer, while deliveries of the 737 MAX to Aeromexico will begin in 2018. The airline's tentative order is in addition to an order for 10 Embraer 190 airplanes.
“The 737 MAX and the 787 Dreamliner provide unmatched passenger comfort and fuel efficiency allowing Aeromexico to expand their fleet, open new routes and serve new long-range markets — continuing their legacy of airline leadership,” Ray Conner, president of Boeing Commercial Airplanes, said in a statement.
Once finalized, the order for 787s will push Boeing's Dreamliner tally back in the black for the year. So far, Boeing has received 24 new orders for its fuel-efficient Dreamliner but has logged 25 cancellations.
Also on Wednesday, Boeing officials reiterated the company's plan to deliver between 35 and 42 787s this year. The jet maker is ramping up production to five 787s monthly by year's end and 10 787s monthly by the end of 2013 between its Everett and North Charleston, S.C., facilities.
