Is CMH easy to connect through?
Port Columbus International is a small, single-terminal airport where nearly everything is a short walk from everything else, making it one of the easier airports in the country to connect through. Because it primarily serves origin-and-destination traffic rather than functioning as a true hub, connections are relatively rare and the airport rarely feels overwhelmed even at peak hours. 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.
