Not competitive
    I was 45 minutes early to my flight from DEN to SAN and because the plane arrived earlier than scheduled, I get screwed because they can leave early. Lady at the desk was unaccommodating and particularly callous to my situation. I will never fly with them ever again.
    Full Fright
    The flight was boarding 45 minutes before the scheduled departure, so I was not allowed on due to an early boarding. Great for people who showed up early, bad for people who showed up at the cut off limit. The best she could do for me is get me on a flight 2 DAYS later, and acted like she was doing me a service. Even if the plane is able to be boarded early, it should NEVER leave before the scheduled departure time. Not only was I not refunded but I had to purchase an emergency ticket with United for $300. I attempted to call the airline 20 minutes prior to the 45 minute cut off time, but was on hold for that entire period. This airline does not have the customer service required to compete with other major airlines.
Frontier Failures
 Good Luck not with us and probably not with the millions of parents and families who has a VERY SPECIAL PERSON and yes they are SPECIAL because they don't see this world as cruel as you do. 


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


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


 I have never had a more infuriating, more frustrating, or more demoralizing experience traveling in my life! 


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