Frontier is the absolute worst
    Frontier Airlines is the absolute worst in an already terrible industry.They treat their customers - you know, the people that keep them in business - like wallets with people attached.
    Full Fright
    $2 for a soda, $2 to pick your seat (which you can't get around if you're booking your flight online), and you pay for CARRY ON bags. If you can't manage to cram your carry on into the device they have at the gate that determines if your bag is considered a carry on by size, then it's $50 (MANDATORY) to check it at the gate. When I asked for a glass of water to make a bottle for my infant daughter during the flight, they charged me for it. Taking a 4-hour flight and plan to watch the in-flight movie/TV? You're going to have to pay for that. Even better, if you elect not to buy the movie/TV viewing privilege, they play the same 5 commercials on the seat-back screen for the entire flight. Most, if not all, airlines suck these days, but Frontier takes it to new heights.I wouldn't recommend them to even my worst enemy.
Frontier Failures
 Air crew forced us to violate FAA’s on-board regulations! 


 Cheaper isn't always better. 


 I fly a fair amount (20+ times per year) and have been on almost all major US carriers, this one takes the cake as the worst!

 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.

 "I detect an accent. Do you understand English?" - Frontier staff... This is clearly discrimination!!
