How to pay less?
- Skip the airport up-charge – A $15 rideshare to a downtown Columbus branch often saves the 10% concession fee + $6/day facility fee baked into CMH rentals. Worth it if you're in the city for a night or two.
- Tweak your calendar – Rates usually dip Tue–Thu and spike on OSU home-game weekends (Sep–Nov). Shift pickup/return by a day on our comparison grid and watch the total drop.
- Downsize the wheels – Economy cars cost less to rent and fill. Only move up a class if you truly need the space; Columbus street parking rewards smaller cars.
- Compare "pay now" vs "pay later" – Prepaid deals can be 10-20% cheaper. Just make sure the change/cancel rules fit your plans before locking in.
- Join the free loyalty programs – They often waive extra-driver fees or toss in upgrades, especially at quieter midweek counters.

FAQs
Is a shuttle required to reach the rental car facility at CMH?
Yes, you have to take a shuttle to get to the rental car building. The shuttles run all day and night, about every 5 minutes, and the ride takes 3 to 5 minutes.
Can I return my rental car after hours?
Yes, all rental companies at CMH let you return cars after they close. You just park in the special return area and put the keys in the secure drop box. An employee will check in your car when the rental counter opens again.
Are there additional fees for renting at the airport versus in the city?
Yes, renting at the airport costs more. The rental companies add about a 10% concession fee and a daily facility fee of $5.50 to $6. You won't find these fees at most rental places in the city.
Do I need to refill the gas tank before returning?
Yes, you need to return your car with the same amount of gas it had when you picked it up, which is usually a full tank. You can find gas stations on Stelzer Road and Hamilton Road near the airport.
Can I use a debit card instead of a credit card at CMH rental counters?
Most rental counters at the airport accept debit cards, but they have strict rules. For example, you may need to show proof of your flight home, pay a higher deposit and provide extra ID. We recommend using a major credit card to make things easier.
