There seems to be a million websites where you can book travel these days. When it comes to searching for travel deals I only use three. The first is Travelocity. I like

Travelocity because it does list the details of the airline, hotel, time leaving, etc. with whom you are booking. They also have a great feature for booking airlines which is the flexible dates button. This allows you to search over a span of days and make a decision about when to travel as opposed to deciding when to travel and then making trying to bend the airlines flights around your plans. For international rates you have to use the international version of Travelocity which is called [ur=http://www.zuji.com/]Zuji[/url] (I don’t know where they got that name but it reminds me of how my stomach feels when I get sick on an airplane)

If you just want the best deal on a certain day, range of days, or quality level I use Hotwire. Hotwire does not tell you what company will be providing the service only what the rating is or the date range. So If I want to stay in Hilton Head I would only get to pick the number of stars of the hotel/resort not the actual hotel itself. Travelocity negotiates for lower prices and thus give you a better deal on average, especially on rental cars and hotels.

If I am going to be staying somewhere for an extended period of time (more than a weekend) I always check out VRBO.com. This stands for Vacation Rentals By Owner. This site connects people who rent out their property to people looking to rent a nice place. Every time we have used this site we have walked away with a deal. You get to negotiate directly with the property owner and if you go during the off season you can really steal a deal. These people are desperate to rent out the property when times are slow. As with any rental some money is better than nothing when your property is sitting there empty.

Other sites I recommend but do not use regularly:
Airfare
Kayak
Sidestep
Travelzoo
Mobissmo — International
Lodging
Venere
Vacation home rentals

Info
City 3-letter Code
airplane seating (find the best seat)
