I always thought that the value of TB points is somewhat fixed at 1.4 to 1.6 cents/point. Today I was looking at a few flights for next year (02/17 weekend). The redemption rate for flights from NYC to CUN and Caribbean islands is roughly 1 cent/point. I've never seen such a low value for TB points. Has this changed recently? Do the rates fluctuate depending on the date we book? Thanks.
