I just read an article in Kiplinger's Personal Finance about saving money on travel. Fairly interesting.
The article is on their web site:

One piece of advice that really caught my attention is to clear your cookies every time you search for travel deals. Apparently some companies ratchet up the prices if they determine you've done previous searches. See the blue box called "Cover your Web Tracks".
