they didnt help us get another flight
    We will not fly with Frontier again. After having paid for tickets for our trip to Costa Rica months in advance, we were informed at the gate that our flight was delayed, but the check in agent said that we should still be able to make our connecting flight through Denver. But that was a big lie.
    Full Fright
    we check our bags ($50 for 2) and go through security. Upon arrival at the gate, we were told that we would arrive in Denver at 11:55 p.m., which was the departure time for our connecting flight to Costa Rica. We asked if they would be able to hold the plan for 10 minutes so that we and the 3-4 other passengers who were in the same situation could make the flight. The gate agent said that she had called the staff in Denver and they refused to hold the flight as it would further increase delays. Frustrated, we asked to be put on the next flight, hoping we could leave the following day at the latest, but she told us that the next flight with available seats was in 6 days. We asked to speak to her manager, who essentially said that out options were to wait six days or that she could (reluctantly) refund us for the cost of our original flight and book a new flight through a different airline. We had to research flights on our own as they had no intentions of helping us secure seats on a new flight. We ended up paying an additional $400 to book last minute tickets on American Airlines, waiting for her to process our refund and get our mailing address to send our checked baggage fee back to us via mail, and then rushing to the next terminal to go through security again and catch our flight. Ultimately, we paid more than we would have if we'd just booked through American months ago. Plus, the lack of customer service or care regarding out situation was infuriating. We are waiting for our flight to Costa Rica as I type this and just praying that they successfully rerouted our bags. Overall a terrible first experience with this airline, and we didn't even make it on the plane.
Frontier Failures
 But Frontier has LIED, telling AMEX we flew all four segments which is an absolute lie! 


 ...we were short a stewardess for our flight and we had to wait for them to arrive from another city...Completely unacceptable. 


 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 


 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 


 Never again. Rude stewardesses, ignorant pilots, and nothing's free. The price isn't cheap enough for this.
