🏢 1. The 1958 Terminal & the $2 Billion Replacement

The most important fact about CMH in 2026 is that the airport you fly through is on its way out. The current terminal opened in 1958 and has been extended and patched for decades into three concourses — A, B and C — around a single central checkpoint area. It works, but it’s dated, and it’s a construction zone: a $2 billion rebuild is underway right beside it, with traffic patterns, parking and curbside access all in flux. The long-stay walking lot has already closed for the work.

The replacement is a near-1-million-square-foot terminal with a single centralized concourse and 36 gates, designed to lift daily passenger capacity by more than 50%, with a consolidated TSA checkpoint and a central market with airfield views. As of late 2025 over 90% of the construction was under contract, and it’s on track to open in early 2029. Until then, expect the practical friction of a major build — give yourself a little extra time at the curb and check your departure concourse, because signage and pickup points keep moving.

Carrier-wise, Southwest is the house airline, working Concourse A, and it’s growing here — adding near-daily San Diego service, doubling Dallas-Love Field to two daily, and pushing Orlando to five flights a day. American, Delta, United, Frontier, Spirit, Breeze and Alaska fill out a schedule that is overwhelmingly domestic.

🛂 2. US Entry, Concourse C Customs & Global Entry

Domestic arrivals at CMH involve no immigration — you walk into the concourse. The border section applies only to the airport’s thin international layer, which runs to a handful of seasonal routes to Canada, Mexico and the Caribbean.

Non-precleared international flights arrive through Concourse C and are processed at the airport’s US Customs and Border Protection facility. CMH also runs a Global Entry enrollment center, on the lower level of the terminal near baggage claim — complete the online application first, then book the in-person interview there. Members use the expedited kiosks on arrival; the free Mobile Passport Control app is the no-cost lane for eligible travelers.

To board a US-bound flight from abroad: visa-waiver nationals need an ESTA (~$21, up to two years); visa-required nationalities need a US visa.

🚌 3. Getting Downtown: the COTA AirConnect

For years Columbus had no decent airport-transit option. That changed with the COTA AirConnect, a direct express bus between the airport and downtown that stops 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 (one 2026 listing shows $2.00 — verify the current fare at cota.com/AirConnect before you ride). The buses are new, with luggage racks and USB charging. For a downtown hotel, this is the cheapest way in by a wide margin.

Rideshare and taxi are barely slower and not expensive given the distance: downtown, the Short North or Ohio State are all about 15–20 minutes and $20–30 by Uber or Lyft. The airport is 6 miles east of downtown via I-670, so even at rush hour the trip stays short.

The trap: the curbside flat-rate “shuttle” tout. With the AirConnect every half hour and metered rideshare a sub-$30 ride, there’s no reason to accept an unmarked operator’s negotiated price.

🛋️ 4. The Escape Lounge: CMH’s One Lounge

CMH has a single lounge, and it’s a good one: the Escape Lounge, airside in Concourse B near Gate 32, open daily 5:00am–8:00pm. It joined the Priority Pass network in June 2024, so Priority Pass and LoungeKey members get in; it also admits American Express Platinum and Delta SkyMiles Reserve cardholders (the latter when flying Delta that day), and takes pay-in walk-ups. The food is a cut above the usual airport-lounge spread — hot and cold dishes with some menu items developed with Columbus chef Avishar Barua, plus vegan and gluten-free options.

There is no Delta Sky Club or other airline lounge at CMH — the Escape Lounge is the entire scene. If your gate is on Concourse A (Southwest), factor the walk over to B before counting on a pre-flight visit.

🍦 5. What to Eat: North Market, German Village & Jeni’s

Columbus’s food anchor is the North Market, a public market established in 1876, home to more than 30 independent vendors a short ride from the airport — a working food hall rather than a tourist set-piece. It’s also the birthplace of Jeni’s Splendid Ice Creams, whose original stand still operates there; the salty-caramel and brambleberry are the ones people queue for.

South of downtown, German Village is the historic neighborhood settled by 19th-century German immigrants, and its food landmark is Schmidt’s Sausage Haus on East Kossuth Street — Bahama Mama sausage and a cream puff the size of a fist. Two more local notes: the Buckeye (a peanut-butter ball half-dipped in chocolate to resemble the nut) is the regional candy, and Columbus has its own thin, square-cut party-cut pizza tradition. Inside the terminal, concessions run local-and-national with hours that follow the flight banks — an early Southwest departure can pre-date the kitchens.

💡 6. Insider: The Short North, German Village & the Layover

CMH is one of the easiest layover airports in the country, for one simple reason: downtown is 6 miles away and the city’s best district sits just north of it.

The move is the Short North Arts District, strung along High Street between downtown and the Ohio State campus — galleries, independent shops and what has become Columbus’s main restaurant corridor, walkable end to end, anchored at its south end by the North Market. On the first Saturday of each month the district runs Gallery Hop, when the galleries open late and High Street fills with street performers — worth timing for if your layover lands on one. South of downtown, German Village rewards a walk for its brick streets and the Book Loft, a secondhand bookshop of 32 rooms. Down on the river, the Scioto Mile and COSI science center round out a compact, walkable core.

Does a layover work? As well as anywhere on this list.

• Door-to-Short-North: ~15–20 minutes each way by rideshare; the AirConnect reaches downtown in ~15–20 minutes, with the Short North a short hop further.
• Return-security buffer: CMH’s lines are usually short, but budget 90 minutes before your flight, and add margin for the construction-affected curbside.
• The verdict: a 4-hour layover leaves roughly 90 minutes to two hours in the Short North after transit and security — enough for North Market, a gallery and a Jeni’s. With 3 hours or less, stay airside (the Escape Lounge makes it easy). With 5+ hours, add German Village or the riverfront without rushing.
