John Glenn Columbus International Airport (CMH) — Airport Guide 2026

🏗️ The Terminal: What’s Here and What’s Coming

The most useful orientation for 2026: the airport you pass through is a 1958 building extended into three concourses — A, B, and C — around a single central security checkpoint. It handles the traffic. It is also a live construction site.

The $2 billion replacement is going up directly alongside the existing structure, which means curbside access, parking, and signage are all shifting. The long-stay walking lot has already closed for the build. The replacement is a near-1-million-square-foot structure with a single centralized concourse and 36 gates, designed to increase daily passenger capacity by more than 50%, with a consolidated TSA checkpoint and a central market with airfield views. Over 90% of construction was under contract as of late 2025. Early 2029 is the target opening.

Until then: check your departure concourse before you arrive, and do not assume the curbside configuration you remember from a prior trip is still the same.

Carrier-wise, Southwest holds Concourse A and is the house airline. It has been growing here — near-daily San Diego service, Dallas-Love Field expanded to two daily, and Orlando at five flights a day. American, Delta, United, Frontier, Spirit, Breeze, and Alaska fill out a schedule that is overwhelmingly domestic.

🛂 Border & Entry

Domestic arrivals clear no immigration — you walk off the plane directly into the concourse. CMH’s international layer is thin: seasonal routes to Canada, Mexico, and the Caribbean. Non-precleared international flights come in through Concourse C, where US Customs and Border Protection handles processing.

The airport runs a Global Entry enrollment center on the lower level of the terminal, near baggage claim. You need to complete the CBP online application before your appointment; the interview happens at the airport. Enrolled members use the expedited kiosks on international arrival. The Mobile Passport Control app is the no-enrollment alternative for eligible visa-waiver travelers.

For boarding a US-bound flight from abroad: visa-waiver nationals need an ESTA — approximately $21, valid for up to two years — filed before departure. Visa-required nationalities need a US visa.

🚌 Getting Into Columbus

Six miles east of downtown via I-670 — close enough that even rush hour keeps the trip under 20 minutes. That distance is the city’s main transport advantage.

🚌 COTA AirConnect

The AirConnect is a direct express bus between the airport and downtown, stopping at the Convention Center and near the main downtown hotels. It runs seven days a week, 6am to 9pm, every 30 minutes, takes about 15–20 minutes, and costs $2.75 one-way as of 2026 (at least one 2026 listing shows $2.00 — verify the current fare at cota.com/AirConnect before you travel). The buses have luggage racks and USB charging. For a downtown hotel, this is the cheapest ride in by a clear margin.

🚗 Rideshare

Downtown, the Short North, and Ohio State are all roughly 15–20 minutes by Uber or Lyft, running $20–30. Even at rush hour the trip stays short.

🛋️ Lounge

CMH has one lounge. The Escape Lounge sits airside in Concourse B near Gate 32, open daily from 5:00am to 8:00pm. It joined Priority Pass and LoungeKey in June 2024. American Express Platinum cardholders are admitted; Delta SkyMiles Reserve cardholders can use it when flying Delta that day. Walk-up pay-in access is available.

The food is above the standard lounge baseline — hot and cold dishes, with some menu items developed with Columbus chef Avishar Barua, plus vegan and gluten-free options.

The Escape Lounge is the only lounge at CMH — no airline club operates here. Southwest gates are in Concourse A, so if that is your departure concourse, factor in the walk over to B before deciding on a pre-flight visit.

🍽️ Columbus Food Worth Knowing

Airport concessions at CMH run on the flight banks. An early Southwest departure can precede the kitchens, so this matters.

North Market is the city’s working food hall, established in 1876, with more than 30 independent vendors. It is also where Jeni’s Splendid Ice Creams was founded — the original stand still operates there, and the salty-caramel and brambleberry are the flavors with the queues. North Market sits at the southern end of the Short North Arts District, about 15 minutes from the airport by rideshare.

South of downtown, German Village is the neighborhood settled by 19th-century German immigrants. The food landmark is Schmidt’s Sausage Haus on East Kossuth Street — the Bahama Mama sausage is the signature, and the cream puff is larger than it has any right to be.

Two more Columbus-specific items: the Buckeye is a peanut-butter ball half-dipped in chocolate, named for the Ohio State nut, and the city has its own square-cut, thin-crust party pizza tradition.

💡 The Layover Case

CMH is one of the more workable layover airports in the country, for a simple reason: 6 miles to downtown, and the city’s best area immediately north of it.

The Short North Arts District runs along High Street between downtown and the Ohio State campus — independent restaurants, galleries, and shops, walkable end to end, with the North Market anchoring the southern end. On the first Saturday of each month, the district runs Gallery Hop: galleries extend their hours and High Street fills with street performers. If your connection falls on one, it is worth timing.

South of downtown, German Village rewards a walk for its brick streets and the Book Loft — a secondhand bookshop that occupies 32 rooms. The Scioto Mile and COSI science center are on the river if you have the time.

Does a layover work?

• 3 hours or less: Stay airside. The Escape Lounge handles the wait comfortably.
• 4 hours: Allow 15–20 minutes door-to-Short-North each way, plus a 90-minute return-security buffer given the construction-affected curbside. That leaves roughly 90 minutes to two hours in the Short North — enough for North Market, a gallery, and Jeni’s, not much else. Do not plan around a best-case pickup time.
• 5+ hours: Add German Village or the riverfront without rushing.

CMH’s domestic security lines are usually short, but the construction period has made curbside unpredictable. The 90-minute buffer is not a conservative estimate — it is the right one.
