Improper or inferior service
    Frontier airlines refused to honor my e-ticket on a recent flight. I checked-in online, however the boarding pass provided would not allow for travel.
    Full Fright
    I was scheduled to fly from MSN to DEN on June 5, 2014 with Frontier Airlines. Several hours before that flight I checked in online and proceeded to the airport. At the TSA security check-point I was apprised that my Frontier Airlines boarding pass would not scan and I was instructed to visit their ticket agent. The ticket agent line had several customers in it, and after a short time it was revealed that all of them had the same problem I did: they were checked in but needed additional documentation to get past security and onto our flight. Rather than provide that document, the ticket agent told us she would not print any boarding documents but would only be available to passengers who were willing to pay $100 to rebook their tickets for the next day. This was still more than 30 minutes prior to take-off of the flight I had already checked-in for. I contacted Frontier customer service via phone and was told they would help rebook me for $50, however when I complained that this was unreasonable and asked that the situation be escalated, I was informed by the floor supervisor (Brian) that because the ticket was issued through an agent that any changes he made would cancel my entire itinerary (this turned out to be untrue according to future conversations with Leslie and Rose at Frontier). After involving my travel agent, we were told Frontier would not honor my ticket at all and I would have to purchase a new one. This was documented by my travel agent Priceline. Frontier's Contract of Carriage clearly states that customers are only required to check-in 45 minutes prior to travel, which I did. If a passenger is then not delivered to their final destination within 2 hours of the original scheduled arrival time they are entitled to 400% of the value of the one-way fare ($67 in my case). I have requested the contractually obligated compensation from Frontier and they have been unresponsive.
Frontier Failures
 The sexism and harassment was visceral and cruel by male agents. 


 They don't get anything right. 


 Depending on which rules they choose to enforce, you can never be assured that you will be granted access to their boarding process. 


 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
