Port Columbus International Airport is my secondary home airport. While it’s 75 miles away from my home (compared to Dayton’s 20 miles), it offers more flights to more hubs than DAY, while still maintaining very reasonable parking rates.

Unfortunately, the three airside concourses are not connected behind security, so food options are practically a bit more limited than Dayton; it’s not possible to get to every restaurant with a given boarding pass.
