Located 6 miles east of downtown Ohio; Port Columbus International Airport (CMH) is one of the nation’s best airports. More than 6.5 million visitors pass through these doors per year. The airport has a very nice feel to it; artwork such as drawing done by kids, paintings, and photographic are all on display and give the airport a real artistic feel. CMH has a very comprehensive ground transportation system put in place to help the 6 million+ visitors get in and out of the airport with virtually no problem. It is up to you to make the best of it by planning ahead.
Shuttle Service
Arch Transportation, Super Shuttle, and Urban Express Transportation all offer shuttle service to the heart of the city. Shuttles from these companies leave every 20 minutes so calling ahead of time is not necessary.
In addition many hotels located near major airports provide free shuttle service between the airport and their business, so call the hotel you plan to book with and ask them if they offer this service.
Bus
Charter buses are readily available, and CMH has recommended the following companies: AC Coach Operations, America Interstate, Arch Express, Bliss Charters, Branson Corp, Cardinal Transportation, Cavalier Tours, Central Cab, and Cleveland Southeastern Trails. Please contact any one of the companies listed above for prices and hours of operation.
Rental Car
CMH has one of the best car rental setups in the United States; the airport has eight rental companies present: Alamo, Avis, Budget, Dollar, Enterprise, Hertz, National, and Thrifty. After you have made your decision and paid for the car you do not have to leave the building to pick it up, because the check-in counters are located on the ground floor of the parking garage.
Limousine & Executive Car
With so many companies in the business; limousine service is getting cheaper by the minute. To find a limousine company that serves the Columbus area do a quick internet search. You can expect to pay $50-$100 an hour for this kind of service and you will receive a very courtesy driver dressed in suit and tie attire.
Taxi Cab
Taxi service is available on an on-demand basis only; IE you cannot make any reservations. There are taxis waiting to do business with you 24 hours a day all year-round, and a trip via cab to the downtown area will cost you approximately $25.00.
Tips
Whenever you are traveling it is better to make reservations in advance; it saves time and money. Check online as well as phoning the companies, because many deals/specials can only be found online. Also ask if your hotel is partnered with any specific rental companies, as hotel and car bundles work out to be cheaper for the most part.
Remember to only ride with authorized drivers; ask to see their airport identification badge and check the vehicle to make sure it is authorized with the airport decal one the bumper.
