Austin-Bergstrom International airport is 1 hour and 23 minutes away.
Houston (Hobby) is 1 hour and 43 minutes away.
I would say if you're flying in Austin is the best place to go.
Both are fairly cheap to fly into, however, Austin is a tad bit closer. All the hotel links below are hotels in Columbus, which is about 25 minutes out from the wedding venue.
