Cheap Flights, Airline Tickets
My sister travels frequently and told me about this site, Kayak.com, she said it is better then Hotwire.com for airline tickets, the site directs you to where to get the tickets, so you are buying directly from the Airline instead of thru them. She said you need to check for prices daily, prices are always varying. She still uses hotwirre to shop around for car rentals, along with other sites.
In case you did not know about the site, check it out.
