Besides keeping an eye on websites to find out if your fare has gone down... call 1800 CELEBRITY. I did and saved. Of course, if you have a T/A, you have to call the T/A with the lower rate and they call Celebrity to get you the difference. Just ask customer svc rep if there are any sales of a particular cat. When I called, they were offering great prices on cat 2. They are very helpful and have the info at their fingertips. I will never understand how pricing works...lol...but like to save money. Hope this helps someone save or upgrade at a great price.
