Aeromexico has applied to the US Department of Transportation (DOT) to begin service between Toluca and Atlanta.
The SkyTeam carrier plans to offer daily flights on the route using Embraer 190 aircraft, it says in a filing with the DOT.
Toluca is the secondary airport serving Mexico City. No carrier operates between Toluca and Atlanta, schedules in Innovata show. However, Aeromexico and Delta Air Lines operate between Mexico City's main international airport and Atlanta non-stop.
Atlanta-based Delta, a fellow SkyTeam carrier, firmed up a $65 million investment in Aeromexico earlier this year.
