Columbus Airport CMH Terminal Map (2025)

Columbus Airport CMH Terminal Map (2025)

Figuring out the Columbus airport layout has gotten complicated with all the outdated info flying around. I’ve flown through John Glenn Columbus International Airport probably a dozen times over the past few years, mostly connecting through on my way to visit friends in Ohio but occasionally as my final destination. The first time I went there, I had zero idea what to expect and ended up wandering the wrong direction for about five minutes. So here’s everything I wish someone had told me.

The Basic Layout

CMH has a single terminal, which already puts it ahead of airports where you need a map and a prayer to find your gate. That terminal splits into three concourses: A, B, and C. Each one handles different airlines and has its own personality, if you can say that about a concourse. Probably should have led with this: the single-terminal setup means you never have to take a shuttle or a train between buildings. Everything connects inside.

Concourse A

This is primarily Southwest Airlines territory. I’ve flown Southwest through CMH more times than anything else, so I know this concourse well. The gates are laid out in a straightforward line, and passenger flow is good even when it’s busy. There are a few dining spots and shops here for the basics. Nothing that’s going to make you arrive early on purpose, but you won’t be stuck staring at a wall either.

Concourse B

Delta and American operate out of Concourse B. It has multiple gates and a broader selection of food and shopping compared to A. There are also lounge areas, which I used once during a three-hour layover. Having a quieter space to sit with a drink and some snacks made the wait completely bearable. I remember being surprised by how uncrowded the lounge was, actually. Maybe word hasn’t gotten out yet.

Concourse C

United and Spirit call Concourse C home. It has its own set of gates and services. The dining and retail options are decent. I flew Spirit out of C once. Well, I should say I tried to fly Spirit. The flight got delayed two hours. But that’s a Spirit problem, not a Concourse C problem. The concourse itself was fine, and I used the time to grab food and charge my phone.

Stuff You’ll Actually Need

Across the whole terminal, you’ll find restrooms, charging stations, and Wi-Fi. The Wi-Fi is complimentary and it works well enough for email and browsing. I’ve even joined video meetings on it during layovers, though the connection got a little shaky once during peak hours.

Food Options

Here’s my honest take on dining at CMH:

Fast food is well represented. McDonald’s and Starbucks are both there for when you just need something quick and familiar. I’ve grabbed a Starbucks before an early morning flight more times than I should admit.

Sit-down dining includes Max and Erma’s, which is a local chain that does burgers and casual American food. If you have time and want an actual meal with a table and a server, it’s a reasonable choice. Not amazing, not bad. Just solid airport food.

Shopping

Hudson News is there for books, magazines, snacks, and travel stuff you forgot to pack. I’ve bought more overpriced phone chargers at airport Hudson stores than I care to count. There are also shops with Ohio-themed gifts and local snacks if you want to bring something back. The buckeye candy is actually pretty good, if you haven’t had it.

Getting To and From CMH

Car Rentals: Hertz, Avis, Enterprise, and the rest have counters near the terminal. There’s a shuttle to the rental facility. I’ve rented from Enterprise there and the process was painless.

Public Transit: COTA buses run from the airport with frequent service. Schedules are available online and posted in the terminal. It’s a cost-effective option if you’re heading into the city.

Parking: You’ve got three main options. Short-term parking is close to the terminal and works for quick pickups and drop-offs. Long-term lots offer daily rates with shuttle service to the terminal. And then there’s valet parking right at the front of the building, which is the most convenient option if you don’t mind paying for it. I used the long-term lot on my last trip and the shuttle came within about seven minutes. No complaints.

Security and Check-In

Security checkpoints are centrally located, which is nice because you clear security once and then can access all three concourses. The standard advice applies: show up two hours early for domestic flights. Check-in counters and baggage drop are right nearby. I’ve found CMH security to be consistently reasonable in terms of wait times. The worst I’ve experienced was maybe twenty-five minutes during a holiday weekend, which is nothing compared to what you’d face at O’Hare.

Lounges

That’s what makes CMH endearing for a Midwest airport. It has lounge options that actually feel worth using. Comfortable seating, complimentary drinks and snacks, and enough quiet that you can get work done or just decompress. Access usually requires a membership or a day pass, but if you travel frequently, it’s worth considering.

Families and Accessibility

CMH has changing stations and play areas for families, which I’ve seen parents use with visible relief. Accessibility features include elevators, ramps, and dedicated staff to assist travelers with disabilities. I once watched an airport employee patiently guide a visually impaired passenger through the entire check-in process. It was one of those small moments that sticks with you.

Information Desks

Staffed information desks are positioned around the terminal. The people working them have been helpful every time I’ve had a question. Digital kiosks are also available for self-service flight checks and general navigation. Between the two, you can get answers to pretty much anything travel-related without having to dig through your phone.

CMH isn’t trying to be flashy. It’s a working airport in a working city, and it does its job well. For a mid-size terminal, it punches above its weight in terms of convenience and layout. If you’re flying through Columbus for the first time, you’ll be fine. I promise the learning curve is about five minutes, max.
