Had to drive 12 hours
    My parents were at the airport an hour before their flight, giving them more than enough time to check in in this small airport. But they were denied boarding because "they were late". Why not just admit that you, Frontier, is cutting on expenses that you cannot provide enough check-in personnel who can handle the number of passengers at the airport?
    Full Fright
    My parents who arrived an hour before flight departure were denied entry and considered late, therefore, was not Frontier's fault. It was Frontier's fault because they had only one person working! This person could not handle the influx of people and became overwhelmed. Denver made the call to close the gate and told the people they are on their own. Next flight out? Two days later. Keep in mind this a very small airport in Bismarck, ND with only 4 gates. You park in front of the doors and walk in. Very simple airport, an hour is sufficient time to arrive when you have normal personnel working. Frontier cuts corners to save money and the consumer suffers. Frontier is taking no responsibility for this mistake they made by their one customer check-in personnel working. Not even a refund was given. My parents were forced to drive now for 12 hrs to Denver.
Frontier Failures
 They don't get anything right. 


 Cheaper isn't always better. 


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


 Worst Airline. Flights always delayed. Poor customer service. Delayed over 3 hours in Denver. I would never fly this Airline. Service has gone down hill over the past few years. 

furious passenger

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