Their website has issues and people get delayed
    If you haven't printed out your boarding pass, make sure you have a very long time before your flight to do it.
    Full Fright
    I arrive with more than 40 minutes to spare for my flight from Trenton to Raleigh. Due to a website issue I was unable to print out a proper boarding pass. Upon arrival the kiosk would not allow me to print my pass as it was under the 45 minute deadline, a deadline that I have never encountered in all my years of flying. The Frontier reps at the counter were of no help and were quite hostile to my (and the 7 other passengers) complaints. They are essentially running a racket. Trenton airport is small and the time to the gate from the ticket counter would have been 5 minutes or less. Yet, Frontier asks (though I have yet to see this information anywhere other than the Trenton ticket counter) you arrive a full 2 hours before a flight to get a boarding pass. My flight was at 6.25 this morning. It was an absurd experience and easily the worst I have ever encountered flying.
Frontier Failures
 The sexism and harassment was visceral and cruel by male agents. 


 They don't get anything right. 


 Cheaper isn't always better. 


 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.

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