Frequently asked questions
What is the runway length at MMIO?
Plan de Guadalupe International Airport has a single paved runway, 17/35, measuring 9,506 feet long and 148 feet wide with an asphalt surface. This length supports a wide range of business jet and turboprop operations without runway-length restrictions typical of shorter fields. The airport sits at a field elevation of 4,778 feet, which reduces aircraft performance on takeoff compared to sea-level airports and should factor into weight-and-balance planning. There is no crosswind runway, so pilots should confirm wind conditions against the 17/35 orientation before scheduling arrivals or departures.
How busy is MMIO for business aviation traffic?
Plan de Guadalupe International Airport recorded 4,430 business aviation operations in 2025 out of 9,977 total annual operations, according to FAA TFMSC data.

The airport carries an ops tier of 1, reflecting its status as a well-documented, higher-traffic field for cross-border business aviation. Monthly figures show a steady climb through the year, with the strongest activity in the fall months.
