Frontier Frontier Airlines Sucks - Phoenix Denver, Colorado

Frontier Airlines is terrible. I flew on Frontier Airlines.  They messed up the booking on my reservation.  I was supposed to return on August 2nd and they told me, I was booked on August 29th.  They couldn't change my flight for a week and then wanted to charge me a fee for correcting their mistake.  They didn't even try to book my on another airline.  I didn't see why I should have to suffer a financial hardship for their mistake. Everyone else in my group got home fine.  I had to buy a one way ticket on another airline. I won't be flying Frontier again.
