Kayak.com

I used Kayak.com's iPhone app to search and book four one-way tickets from Orlando, FL to Minneapolis, MN for April 8th 2012.

I entered our information and our credit card and Kayak said that the flight was booked. I got a confirmation email from Kayak and from the airline, Frontier Airlines. I noticed immediately that the tickets were booked at a wrong date; they were confirmed for April 10th 2012. I emailed Kayak and they said that on the first submission, the travel date was April 8th and after they notified me that the fare had increased, the second submission was for April 10th travel, which is completely untrue; I was not notified during or after booking that the date would be changed and that they also said to contact Frontier directly.

I called the airline and spoke with a manager. They will not cancel my tickets, even within an hour of booking them, and that they would be glad to switch me to the 8th for $60 more per ticket!

Neither Kayak nor Frontier will take the blame and I have the wrong tickets. I now have to file a dispute with my credit card.

I used Kayak Explorer to find a ticket. I found a great deal from Boston to San Diego. A link directed me to Cheap Tickets where there were about seven choices in the same low price range. I booked my ticket and received a confirmation from Cheap Tickets with flight locator number. My credit card was charged. I booked a hotel room and then hours later got an email to say the flight was not available. The flights were available; they were just not willing to give it to me for the price that Kayak and Cheap Tickets advertised. I don't understand how major airlines works together with a company that offers a bogus fare and charges a person's credit card.
