Do *not* book your flight directly on Kayak.com. Their site is misleading and says that your flight will be managed by Travelocity, however in booking it on Kayak and not directly on Travelocity.com, you are not afforded any of the benefits of a Travelocity customer (namely, you cannot benefit from price or service guarantees).
Go to the travel agency site and book directly. DO NOT BOOK ON KAYAK.COM!
(Also their customer service has yet to reply to my complaint.)Edited: 1:26 am, December 25, 2012
