If you'd like to have some extra spending money on your trip to Columbus, then listen up! As every experienced jet-setter will tell you, don't book at the very last minute. Airfares are generally more expensive close to the departure date. Also, do some online research and compare your options. If your destination has a few airports, you may be able to pick up a terrific deal by flying into a smaller terminal. Last of all, another easy way to save some cash is be ready to book fast. If you find an amazing deal, don't think twice — grab it while you can.
