John Glenn Columbus Airport (CMH) with Kids: Every Family Facility, Mapped

CMH doesn't list one. Its full amenities directory covers restaurants, shops, nursing rooms, the meditation room and pet relief, but no children's play area. The airport doesn't state that none exists. Kids do tend to love the PeppTron robot pizza machine before security and the Jeni's ice cream vending machines in every concourse.

CMH has private nursing rooms in each of Concourses A, B and C, and another in baggage claim before security. The airport doesn't publish gate positions, hours or a feature list, so ask an Airport Ambassador or look for signage once you're through your checkpoint.

Yes. CMH has a universal changing table that staff will deploy to a family restroom before security or in any concourse. Call 614.239.4029 to request it; signs in the family restrooms explain how and link to instructions. It's sized for older children and adults, which helps if your child has outgrown a standard fold-down table.

CMH's site doesn't list one. Instead it offers the Journey Care Kit for travellers with visible and hidden disabilities, with Sunflower lanyards and a social story called 'Journey Care Kit: Ready to take off!' Email the airport at least 45 days before your flight with your mailing address to have one sent. Paw Force One therapy dogs also visit the terminal.

CMH doesn't publish one. Each concourse has its own TSA checkpoint, open 4am to 8:30pm, and TSA stays open no later than 10pm if flights run late. Standard TSA family rules apply: children 12 and under keep their shoes on, strollers go through the X-ray, and formula and breast milk are allowed over 3.4 oz.

Southwest uses Concourse A. American and United use Concourse B. Air Canada, Alaska, Breeze, Delta, Frontier, JetBlue, Lufthansa and Sun Country use Concourse C. If you're on Allegiant, you'll fly from Rickenbacker (LCK) instead.

CMH doesn't mention stroller rental. SmarteCarte luggage carts cost $6 in the garage, at the curb and in baggage claim, with 25 cents back when you return one. Bring your own stroller and gate-check it under your airline's rules.

TSA's national rules apply. Formula, breast milk and baby food are allowed in your carry-on above the 3.4 oz (100 ml) limit and don't need to fit in the quart bag. Tell the officer at the start of screening and take them out of your bag. You can carry your child through the walk-through metal detector.
