I find that Frontier has some great flight times at reasonable prices if you don't mind sitting where they put you. The employees that man the boarding stations don't know much about anything. When asked about the terminal the plane would land at, they didn't know and didn't know how to find out. There were two people there that could not answer that question. The seats are hard plastic so take something for you back to make it more comfortable if the flight will long. I also find that employees are less personable than Southwest. They are robots that don't know how to show friendliness.
