John Glenn Columbus International Airport (CMH) is located approximately six miles northeast of downtown Columbus, Ohio, and serves as the region’s primary airport. Renamed in 2016 to honor Ohio native and space pioneer John Glenn, CMH plays a central role in connecting Columbus to the rest of the country and beyond. In 2024, the airport handled an estimated 8.5 million passengers, making it one of the busiest mid-sized airports in the Midwest.
CMH features a single-terminal layout that branches into three concourses—A, B, and C—allowing for seamless movement post-security. The airport has earned a reputation for being clean, efficient, and traveler-friendly, offering a well-rounded mix of amenities without the sprawl of larger airports.
One of CMH’s biggest advantages is its compact terminal design, which simplifies navigation and eliminates long walks or confusing shuttle transfers. All concourses are accessible after passing through a single centralized TSA checkpoint.
Major airlines serving Columbus include Southwest, Delta, American, United, Spirit, and Alaska Airlines. Seasonal routes to Canada are occasionally operated by Air Canada, connecting Columbus with Toronto and other destinations.
Travelers will find free high-speed Wi-Fi, charging stations, and a variety of dining options, many of which showcase Columbus’s local food scene.
Concourse A
Gates A1–A7
This is the dedicated space for Southwest Airlines, which dominates in terms of passenger numbers at CMH. From Concourse A, travelers can catch frequent flights to high-demand destinations like Chicago Midway, Las Vegas, Orlando, and Atlanta.
Dining & Services:
- Eddie George’s Grille 27 pays tribute to the Ohio State football legend and serves burgers, wings, and regional beers.
- Auntie Anne’s and Starbucks cover quick snacks and coffee cravings.
- Compact retail kiosks offer essentials and Ohio-themed souvenirs.
Concourse A is closest to the terminal entrance, meaning travelers can get from curb to gate in minutes—a major perk for short trips or early flights.
Concourse B
Gates B15–B36
Concourse B is home to American Airlines, Delta Air Lines, and Air Canada’s seasonal international services. It recently underwent a significant upgrade in 2023, adding modern furniture, new lighting, and more space for dining and relaxation.
This is where you’ll typically board flights to New York, Dallas, Charlotte, Miami, and other popular destinations.
Dining Highlights:
- The Columbus Ale House serves up regional craft beers from local favorites like Land-Grant Brewing Co. and Seventh Son.

Concourse B now also includes an Admirals Club lounge (opened in 2025), giving eligible travelers access to premium seating, drinks, and panoramic airfield views.
Concourse C
Gates C46–C56
Concourse C is the smallest of the three and hosts United Airlines, Spirit Airlines, and Alaska Airlines. Despite its size, it covers an impressive range of destinations including Denver, Houston, Seattle, and Florida cities served by budget carriers.
What You’ll Find:
Dining is limited but includes Charleys Philly Steaks and a few vending options.
USB charging ports and updated seating make it a quiet and productive space to wait for your flight.
Due to its layout and lighter foot traffic, Concourse C is ideal for travelers seeking a calm environment.

Recent Enhancements & Future Plans
In 2024, CMH completed a $50 million renovation, adding:
- Expanded seating at gate areas
- Updated restrooms
- New local dining concepts
In early 2025, the American Airlines Admirals Club opened in Concourse B, offering elevated comfort and local flair.
Looking ahead, the airport plans to begin construction on a brand-new terminal in 2026, part of a $2 billion modernization project aimed at increasing capacity and boosting international connectivity. The new terminal is expected to open by 2030.
CMH is also moving toward carbon neutrality by 2035, with eco-initiatives such as EV charging stations, LED lighting, and efficient HVAC systems.
Final Thoughts
John Glenn Columbus International Airport combines the accessibility of a regional airport with amenities found in much larger terminals. Its layout is intuitive, security wait times are typically short, and the presence of Ohio-based brands adds a personal touch. Whether you’re flying Southwest from Concourse A or heading to the West Coast with Alaska from Concourse C, CMH ensures a smooth and comfortable experience from check-in to takeoff.
