As of 2024, airlines with regular scheduled service include American Airlines, Delta Air Lines, United Airlines, Southwest Airlines, Spirit Airlines, Frontier Airlines, and Allegiant Air. Alaska Airlines has also operated seasonal or limited service into CMH.

Most nonstop routes out of CMH connect to major hubs: Delta runs nonstop service to Atlanta and Detroit, United connects to Chicago O'Hare, Newark, and Washington Dulles, and American serves Charlotte, Philadelphia, and Dallas/Fort Worth. Southwest offers nonstop flights to cities including Chicago Midway, Baltimore, and Nashville. Budget carriers Spirit and Frontier typically serve Florida destinations and a handful of Sun Belt cities, often at lower base fares but with fees for carry-on bags and seat selection.

CMH has one terminal with two concourses (B and C), which keeps the airport compact and easy to navigate. Security to gate typically takes under 20 minutes during off-peak hours, which is a genuine advantage over larger connecting hubs.

Airline routes and schedules shift seasonally, so confirm current nonstop availability on the CMH airport website (flycolumbus.com) or your preferred booking platform before planning around a specific route.
