I fly about 100,000 miles per year and I choose Frontier whenever I can. I have never had a flight cancelled by them and they have one of the best on-time records in the airline business. The planes are new, clean, and flight crews are generally pleasant. Buy on board snacks are considerably better and healthier (fresher) than the average airline onboard snacks. They had the lowest passenger complaint ratio last month, so most people are satisfied, it seems.
