John Glenn Columbus Airport (CMH): Terminal Map, Airlines and Ground Transport

John Glenn Columbus International Airport (CMH) has one passenger terminal with three concourses: A, B and C. Each concourse has its own security checkpoint, so check your airline and boarding pass before joining a line. The terminal is compact compared with the largest U.S. hubs, but choosing the correct concourse before screening saves an unnecessary walk back through the ticketing lobby.

This guide explains the current CMH layout, airline locations and the practical choices for getting between the airport and Columbus. Airport operations can change, so use the live official CMH terminal map and your airline app for your final gate and checkpoint.

CMH terminal map at a glance

The ticketing lobby, baggage claim and ground transportation areas are in the central terminal. Concourses A, B and C branch from that building after separate security checkpoints. You cannot assume that every post-security area connects to every other concourse. Confirm the letter on your boarding pass before screening.

Those assignments reflect the airport’s current passenger guidance as reviewed in August 2026. Seasonal operations and irregular flights can move, and Spirit ceased operations in May 2026. Allegiant passengers should pay special attention: Allegiant operates from Rickenbacker International Airport (LCK), not CMH. The official airline directory is the best source when an itinerary or third-party booking page is unclear.

Departures: check-in and security

1. Confirm that your airport code is CMH rather than LCK.
2. Check in with your airline and verify the concourse letter.
3. If checking a bag, use the airline counter in the ticketing lobby.
4. Enter the security checkpoint for your assigned concourse.
5. After screening, follow the gate number shown in the airline app or departure display.

Because airport construction can affect parking and access, FlyColumbus currently recommends allowing enough time to enter the terminal at least 90 minutes before a domestic flight and two hours before an international flight. That is an airport planning recommendation, not a guarantee: holidays, weather and airline bag cutoffs can require more time. Check the airport’s live security information before leaving.

Arrivals and baggage claim

Follow signs from the gate to baggage claim on the arrivals level. Flight information displays identify the correct carousel. If someone is collecting you, share your airline, flight number and actual arrival status—not only the scheduled time. Drivers should use the airport’s designated pickup areas and should not leave a vehicle unattended at the curb.

Getting from CMH to downtown Columbus

CMH is east of central Columbus. The best option depends on cost, luggage, arrival time and whether you need a vehicle after reaching the city.

Rideshare

Uber and Lyft provide airport pickups. After requesting a ride, go to the arrivals level, cross the arrivals drive to the ground transportation area and follow the posted column markers. Always match the license plate and driver in the app before entering.

Taxi and prearranged shuttle

Taxis are available on the ground transportation level. Hotel shuttles, charter vehicles and prearranged transportation use signed zones, which may differ from the rideshare area. Confirm pickup instructions with the operator rather than waiting at a general curb.

COTA public transit

The Central Ohio Transit Authority (COTA) is the region’s public transit provider. Routes and schedules can change, so plan the exact trip using the COTA Trip Planner for your arrival day. Public transit can be economical for a light traveler, while a direct ride may be easier late at night or with several bags.

Rental cars

Follow airport signs for rental-car transportation and the Rental Car Center. Reserve ahead during busy periods and verify the company’s hours if arriving late. Before leaving the lot, photograph the vehicle, set the destination while parked and note the fuel and return terms. Our broader airport rental-car guide covers counter timing and pickup checks.

CMH parking choices

CMH offers garage, short-term, long-term, economy-lot and valet choices, but availability and rates can change. Short-term parking favors pickups and brief trips; long-term or economy options generally make more sense for longer travel. Check the live official parking status and rates before driving to the airport. Compare the full trip cost—not only the advertised daily rate—and leave time for any shuttle ride. See also our guide to the real cost of airport parking.

Food, shopping and the CMH lounge

Food, coffee and shops are available before security and in all three concourses, but individual hours can vary with flight schedules. CMH lists the Escape Lounge in Concourse B. Do not plan on moving between concourses after security solely to visit a restaurant or lounge; choose an option accessible from your own concourse and verify hours in the airport’s current directory.

Accessibility and family travel

Request wheelchair service through the airline before travel. COTA also provides paratransit for eligible riders. Travelers with children, medication, mobility equipment or service animals should review airline and TSA requirements in advance. The airport information desk can help with terminal directions, but the airline controls check-in, bags, seat assignments and wheelchair dispatch.
