Frontier Airlines charged my credit card almost $100 more than the fare that I found on their website. After I found a fare that was already high to start with on their own website and started the reservation process, they apparently raised the price. Their system would not complete the transaction. I subsequently agreed to a higher price with one of their telephone reservation agents because I had committed to making the trip. I have now discovered that they charged my credit card substantially more than I agreed to and that was shown on the confirmation of my reservation.The original price that I was offered on their website was $529.30. The best that the reservation agent was able to offer and the amount shown on the confirmation was $554.46. My credit card has been charged $613.30. Not only did they raise the price while I was making the reservation, they apparently are continuing to raise the price.
