Connecting
at CMH.
Yes, if you're arriving from another country.

The exception is a flight that was precleared before departure, such as from Canada, Ireland or Abu Dhabi. Domestic-to-domestic connections stay airside.

Layover questions
CMH, answered.
Do I have to go through security again on a connection at CMH?
Yes, if you're arriving from another country. Every international arrival at CMH clears passport control and customs, collects and rechecks checked bags, and goes back through TSA security before a connecting flight, even a domestic one. The exception is a flight that was precleared before departure, such as from Canada, Ireland or Abu Dhabi. Domestic-to-domestic connections stay airside.
Can I check the security wait time at CMH?
LYVR shows live security wait times for each checkpoint, grouped by terminal, refreshed every couple of minutes.
Which lounges at CMH can I use on a layover?
LYVR lists 1 lounge at CMH, 1 of them on Priority Pass. Which ones you can get into depends on your ticket, airline status, credit card or a lounge membership. Each lounge on this page lists what gets you in, and LYVR checks it against your own profile.
How much time do I need for a layover at CMH?
It depends on your terminals, whether you re-clear security or customs, and how far the gates are apart. LYVR adds up deplaning, every walk on the indoor map, any checkpoints your connection passes and the boarding door time, then shows exactly how much time you have to spare.
Is a 1 hour layover enough at CMH?
For a domestic connection on one ticket, usually yes. Arriving at CMH from another country, no: you clear passport control and customs, collect and recheck checked bags and go back through TSA security, so plan on 2.5 to 3 hours, unless your flight was precleared before departure. If a delay makes you miss a connection on one ticket, the airline rebooks you. LYVR works out your exact time to spare for your own two gates.
What is there to do on a layover at CMH?
With an hour or two, eat near your gate and walk the terminal. With more, CMH's 1 lounge (1 on Priority Pass) have quiet seats, food and often showers. LYVR's Explore tab lists every restaurant, bar and shop near your gate with the walk time, so you only see what fits in your layover.
Can I leave the airport on a layover at CMH?
Yes, if you have time. Arriving from abroad, you've already cleared US immigration and customs at CMH, so leaving only adds the trip into Columbus and back and TSA security on the return. As a rule of thumb, it's worth it with about 4 hours on a domestic layover and 6 on an international one. LYVR checks the ride each way and how much time you'd really have in Columbus.
