Their charges are overwhelming
    Do not be fooled by the low cost of airfare they promote because after they nickel and dime you, it would be a totally different story.
    Full Fright
    Denver to SFO, July 2nd. This is an inferior airline due to its policies and poor customer service. It is a myth that it costs less when you are done with their nickle and diming. The flight crews are fine, it is everything leading up to it. The extra charges are over the top. The only thing that does not cost is a glass of water and using the toilet but I would not be surprised if this will change. I witnessed a young woman traveling with a baby who had paid for a checked bag. When she decided should needed to carry it on she offered to pay the difference and was told there was no way to refund and she would have to pay full carry-on fees or she could not board. Robbery by any other name. Any company that gouges the customer to stay in business needs to close its doors. Buyer beware.
Frontier Failures
 The sexism and harassment was visceral and cruel by male agents. 


 Air crew forced us to violate FAA’s on-board regulations! 


 Cheaper isn't always better. 


 I fly a fair amount (20+ times per year) and have been on almost all major US carriers, this one takes the cake as the worst!

 I have never had a more infuriating, more frustrating, or more demoralizing experience traveling in my life!
