No documented post-security indoor relief area. The only confirmed relief area is outdoor and pre-security (outside baggage claim) — using it during a layover would require re-clearing security. Service-animal users have to request ad-hoc assistance from a gate agent for post-security relief.
CMH documents a single outdoor pet relief area outside the southernmost door of the baggage-claim level. The airport's own page and a May 2026 third-party guide both indicate there is no documented post-security indoor relief facility — service-animal users are advised to ask a gate agent for assistance after passing through security.
Outdoor and open-air per the airport's own page; some third-party sources call it 'landscaped' and one older third-party source describes a small fenced enclosure, but airport-side fencing is not confirmed by CMH's own page. Serves all CMH airlines on arrival. Field verification recommended — enclosure construction not documented online.
