We know decisions about purchasing airfare are important and can be complicated so we created this cost calculator to help users size up the cost of flying from the Northwest Arkansas National Airport compared to airports in Tulsa and Kansas City. It’s possible that the airfares are lower at those other airports, but it’s probably not the case once you factor in the cost of driving, the cost of parking and other costs. How much time are you willing to invest into saving a few bucks? You do the math. Our calculator walks you through the process.
