Finding great airfares via RSS: Travelocity and farecompare

Travelocity has executed on a system they call Instant Flight Deal Notification With RSS that will deliver fare information to your newsreader via syndication. Just pick your origin city and up to 5 destinations, and they’ll let you know when the fares are discounted. Here’s what they say on the site:

Find out fast when fares to your favorite destinations drop by at least 20%! It’s easy, thanks to Travelocity’s new RSS feed. Just choose the destinations you’d like us to watch, and we’ll keep you informed though My Yahoo!, My MSN, or another RSS news reader of your choice.

My initial testing found some great fares, and a few cents cheaper even than Kayak but I couldn’t search all the cities I like.

Another similar service called farecompare also sends discount rates via RSS. It had all the cities I wanted to track, but the fares weren’t as good.
