Columbus (CMH) TSA wait times — the real source.

OFFICIAL LIVE FEED

John Glenn Columbus International Airport publishes official live security wait times. The button below opens the airport's own live board — the only measured source for CMH. CMH publishes a live wait-time widget on its security page (occasionally shows "unavailable").

PreCheck: available

How early should you arrive at CMH?

No airport-specific arrival guidance is published — the TSA standard applies: 2 hours before domestic flights, 3 hours before international.

The honest truth about "live TSA wait times." The TSA shut down its public wait-time API years ago and publishes no live checkpoint feed for any airport. Every website showing "live" TSA waits for hundreds of airports is showing you a model or a guess. The only real live numbers come from the airports themselves — so we verified all 20 major airports by hand (July 26, 2026) and link you straight to the official source. 17 of 20 publish a live feed; Chicago Midway and Milwaukee Mitchell publish none.
