I was looking at air fare to mexico, cancun, cozumel or ixtapa. the air fare is outragious. What site do you use to find the best air fare?
I like sidestep.com It incorporates zillions of sites' search engines (including Kayak) in its listings. When you book, it takes you to the site of the best price it found for you (might be kayak, hotels.com, etc) so there is no fee to use sidestep.com. It also has a graph if your dates are flexible that shows the historical high and low prices of the airfare between your city and your destination.
Good for air, hotel, car, cruise, etc.
