Terán Air Base, designated ICAO code MMTB, is a Mexican Air Force installation located near Tuxtla Gutiérrez, the capital city of Chiapas state in southern Mexico. It serves primarily military and government aviation purposes rather than commercial passenger operations. The base supports regional defense and security missions in the Chiapas area, a strategically significant region given its proximity to the Guatemalan border. It does not operate scheduled commercial flights and has no assigned IATA code, reflecting its non-commercial status.
