I flew Frontier for the first time earlier this month. The outgoing flight was fine. The return flight was cancelled! <img src="http://www.traveltalkonline.com/forums/images/graemlins/duh.gif" alt="" /> Fortunately I was able to basically do a walk up booking on Southwest for almost the same money. Frontier gave me back my money and gave me a $200 voucher. I will definitely use it, and hopefully the next trip will turn out better. I haven't gotten the credit card bill yet for the four hours at the airport bar! <img src="http://www.traveltalkonline.com/forums/images/graemlins/Blush.gif" alt="" /> Frontier appears to be in a massive build up of flights. I hope they can be trusted better than Allegiant, which has had a TON of maintenance problems, including multiple instances of no working a/c!!! <img src="http://www.traveltalkonline.com/forums/images/graemlins/Shocked.gif" alt="" />
