Hands down worst customer service of any airline/company
    I first attempted to call their customer service line to resolve my problem, and everytime I called there was a 45+ minute wait, so I emailed instead. But issue still didn't get resolved.
    Full Fright
    Keep in mind it takes them 3-4 days to respond to emails (which I find unacceptable) so I tried to work it out with them for a few weeks. Following my initial complaint, the customer service rep went in and deleted all my airline miles I had accumulated, seeing as how my initial contact with them was resolving and issue on using them. Second, they didn't even bother to tell me they deleted the miles, they tried to play me for being ignorant and said I had no miles. Three weeks of battling with them, they have restored part of my points and refuse to assist with my initial issue of using the points. Absolutely worst customer service ever!
Frontier Failures
 The sexism and harassment was visceral and cruel by male agents. 


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


 The worst airline I've flown. 


 This airline is an absolute joke, they nickel and dime you for everything, there is no customer service, and apparently the idea of a flight going as planned is impossible. With the arrival of United and Delta to our area never again will I fly with Frontier 


 This airline is awful. They nickel and dime you, they are rude and unorganized. I will never fly this airline again...EVER
