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


 Unacceptable...I will stick with Southwest Airlines from now on, and tell anyone else to do the same. the few bucks saved wasn't worth the inconvenience.

 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!

 Traveling Frontier has been one of the worst experiences I have ever had. Rude, disrespectful and completely unhelpful. I would highly discourage traveling with them 


 "I detect an accent. Do you understand English?" - Frontier staff... This is clearly discrimination!!
