Tips for 35 min Connections
Because CMH has just one terminal, gate-to-gate walks rarely take more than 8-10 minutes even at opposite ends.
If your itinerary includes an international arrival, budget extra time for CBP processing since the airport handles far fewer international flights than major hubs.
Southwest passengers connecting between flights should note that CMH is not a Southwest hub, so schedules may have longer gaps than at true connection points.
The single security checkpoint moves quickly outside of early morning and early evening peaks, so precheck travelers rarely wait more than a few minutes.
Food and shopping options are limited compared to major hubs, so grab something quickly if you have a longer layover.

High risk
Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
Getting Between Concourses
All gates sit within one compact terminal building connected by post-security walkways, so no train or shuttle is needed between concourses. Passengers arriving internationally must clear CBP and recheck bags/security before continuing to a connecting flight, which adds the only real transit friction at CMH.
