John Glenn Columbus International Airport

Overview

John Glenn Columbus International Airport, identified as CMH and KCMH, is the main large airport serving Columbus, United States. For most visitors, it is the city’s most practical air gateway, with a scale that supports regular domestic travel while still feeling manageable compared with some of the country’s biggest hubs. The airport sits at an elevation of 815 feet (248 m) and operates on Eastern Time in the America/New_York zone, which is useful to keep in mind when planning onward transport, hotel check-in, or early departures.

Airfield Details

• Two lighted asphalt runways support airport operations in a range of conditions.
• Runway 10L/28R measures 8,000 feet.
• Runway 10R/28L measures 10,114 feet.
• The longer parallel runway helps accommodate heavier traffic and larger aircraft needs.
• Lighting on both runways supports arrivals and departures after dark and during lower-visibility periods.

What This Means for Travelers

For passengers, the most useful takeaway is that CMH combines the capabilities of a large airport with the convenience expected from a city-focused gateway. Its parallel runway layout helps keep traffic moving efficiently, which can matter during busy travel periods and weather-related disruptions. Because it serves Columbus directly, the airport works well for both business trips and leisure visits centered on the city, nearby universities, sporting events, and regional road travel across central Ohio.

Planning Your Visit

Before traveling, check the official airport website at https://flycolumbus.com/ for terminal guidance, parking updates, ground transportation options, and current passenger information. Since Columbus follows Eastern Time, double-check flight times if you are connecting from another U.S. time zone. It is also wise to review airline check-in deadlines and airport notices in advance, especially for early morning departures, holiday weekends, or winter travel when schedules can tighten quickly.
