John Glenn Columbus International Airport security wait times

~15 min through security at CMH, from our airport directory. Early mornings and holiday weekends run longer.

Budget that on top of check-in or bag drop and the walk to your gate. For your exact leave-home time, enter your flight above: the plan uses the live wait when there is one.

Arrive 90 minutes early, earlier for peaks. Hit the airport 90 minutes before domestic departures; add buffer for 6–9am Southwest banks when lines spike.
