Dayton Airport is generally our first choice.
Dayton International Airport (DAY) is a 45 minute drive north. Generally, rush hour delays are fairly insignificant (~5-10 minutes).
Port Columbus International Airport (CMH) is a 1½ hour drive. Add 15-30 minutes if traveling during rush hour to be safe.
Cincinnati / Northern Kentucky International Airport (CVG) is roughly a 60 minute drive south if it’s not rush hour. Add 15-30 minutes if traveling during rush hour to be safe.
