Yesterday we took the GoBus from Ohio University to Port Columbus Airport. It was cheaper and more comfortable way to get to Columbus at about $10.76 one-way.  The other taxi services range from $25 to $120 excluding tips.  The trip took 2 hours and 10 minutes due to about 5 stops.

It is best to buy your ticket ahead of time if going to Columbus but on the way back you can pay the driver.
