Mexico City International Airport (MEX) may not be getting replaced, but it could get expanded.

Mexico City Daily reports that the Mexico City Airport Group (GAMC) has drafted plans to add a third terminal to the airport and also is considering a fourth terminal.

New Mexican President also announced that construction on the $4.1-billion Santa Lucia airport, also serving Mexico City, will begin next month.

The change of governments in Mexico has derailed plans to replace MEX with a $13-billion facility on another site; construction has been halted on the partially completed new airport in Texcoco.

GAMC CEO Gerardo Ferrando said the new terminal would be for arriving passengers only and is intended to ease overcrowding at the airport.

“There are certain discomforts at T1 and T2, that’s why T3 is coming and eventually T4. Everything that will be done is for greater comfort,” he said.

Toluca International Airport, also located in the Valley of Mexico, also could help meet rising demand for air travel: GACM is moving to acquire control of Toluca.
