It is only from reading this Flyer Talk Forum that I am even aware that you can re-fare your ticket if the price goes down. Like most of us, I normally travel on business and am not really concerned about the price. Last year, I flew ONT to FLL on New Year's Day for pleasure, on points. I booked the flight on the day it became available for around 19,700 points.
This year, I did the same thing, only it was in excess of 27,200 points. Hmm, I guess I'll keep an eye on the price. It's only a couple weeks later, and I've already re-booked 5 times, lowering the cost, so far, to 19,300 points, less than last year.
Thanks Flyer Talk!
