<p>Another idea-
Just looked up flights from our airport to IND. It looks like she could fly on Frontier for a good price. It might be worth my time to save the miles for a later trip and pay for her ticket. Since each leg is 4 hours of driving time for me.
Frontier is new to our area. The flight goes through Denver. Looks like the first leg is operated by Republic and the 2nd by Frontier. She would have a decent layover time. Any experience with Frontier, Republic or changing planes in Denver?</p>
