Online Travel with Kayak.com

I'm not sure why I haven't seen much written about this great new site someone referred me to. Maybe I'm just behind the times, but Kayak.com is a great travel search site.

• Simple intro page with helpful details. The calendar displays the next two months, since people often schedule travel a month ahead of time. Cities auto-complete so typing BOS will bring up Boston or Bossaso, Somalia.
• Displays results as they are returned. This is a nice feature because it takes a while to search so many different sites.
  
• Easy search modification. Sliders let you modify departure and arrival windows, with quick results displayed. This is a very quick, intuitive feature.

There are certainly some downsides - ads are everywhere, to the point of being pretty distracting. Search results are sometimes inconsistent. But overall, it's a very useful tool that I'll continue to use until someone tells me there's something better!
