Charges for anything extra
    I am so frustrated with Frontier's new policies to charge you extra for everything: seat assignment, carry-on bag, checked bag, coffee on the flight, etc.
    Full Fright
    I'm sure they will be charging for seat belts soon. Frontier used to be my favorite airline, but now I avoid them at all costs. I am happy to pay a little extra (or not in many cases) to fly Southwest Airlines where they still let you check a bag for free and carry on a bag with your personal item. If Southwest isn't available, I look for anything other than Frontier now. We are spreading the word and on my recent flight from Cincinnati, I heard several passengers complaining saying they wouldn't fly Frontier anymore - it's so ridiculous. And because passengers have become so frustrated, this has caused Frontier employees to lose their patience... what was once one of the friendliest airlines is now the rudest. Shame on you, Frontier - this is the worst example of customer service I have seen in many years
Frontier Failures
 But Frontier has LIED, telling AMEX we flew all four segments which is an absolute lie! 


 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!!
