I like Frontier. However, the cost had gotten way to high. We flew out of St. Louis to Mobay direct the last 5 years. We found Southwest out of Midway (Chicago) for $650.00 for both of us. The Frontier was up to $1450.00 for both of us and it is about the same distance to both airports. Frontier had free direct TV in all seats down and back. Never had a problem flying Frontier, just the cost.
