John Glenn Columbus International Airport sits six miles east of downtown Columbus, Ohio. Managed by the Columbus Regional Airport Authority, it serves primarily as a passenger airport providing 148 daily non-stop flights to 31 airports. The facility handles major domestic routes and seasonal charters, playing a vital aviation role for the central Ohio region while preparing for future expansion through its ongoing CMH Next modernization project.
The airport is organized around a single commercial terminal divided into three non-connected airside concourses—A, B, and C—housing 29 usable gates. Each concourse features its own separate TSA security checkpoint. Major airline alliances and carriers are distributed across these areas: Southwest operates out of Concourse A, American, United, and Air Canada serve Concourse B, while Delta, Alaska, Frontier, Breeze, and Sun Country fly from Concourse C.
01 Terminals & concourses
The single main terminal hosts three separate concourses that each maintain their own TSA security checkpoint. Concourse C houses the customs facility for non-precleared international arrivals.

Lost, delayed or damaged baggage at CMH
If your checked bag doesn't turn up on the belt, act before you leave the baggage-claim area — that's where every airline keeps its Baggage Service Office.
- Go to your airline's Baggage Service Office in the baggage-claim hall of your arrival terminal.
- File a Property Irregularity Report (PIR) and get your file reference (WorldTracer) number. Keep your bag-tag receipt and boarding pass.
- Track it online using that reference on your airline's baggage-tracking page — most bags are located within 24–48 hours.
- Claim your essentials. On delayed bags airlines reimburse reasonable interim purchases (toiletries, clothing) — keep receipts. International trips are covered by the Montreal Convention.
- If it's truly lost (generally after 21 days) or damaged, file the claim at the same office — damage must be reported before you leave the airport.
Left something in the terminal (not a checked bag)? That's handled by the airport Lost & Found. Items left at a TSA security checkpoint are held by the TSA, not the airline.
