Cheap Airfare, Hotel Reservations, Car Rentals – Kayak.com
Thanks to Caroline: 
I dont know if ya’ll have used it, but the site http://www.kayak.com is the best Ive used to get tickets, cars, hotels.
Its way better than Sidestep, you dont have to download anything, it spiderwebs a huge number of sites, and is easy to use.
I guess I’ll have to check Kayak out. Thanks for the tip.
Hi!
That was useful. I have a site of my own, on discounted airfares, that is related to your blog, so I hope this is of use too.
