Avianca Lifemiles expiration changing (for the worse)!
Effective April 15, redeeming will no longer defer (reset) Avianca Lifemiles expiration, only earning (including transfer from Citi TYP) will.
Also effective April 15, those without Avianca status and without an Avianca credit card will have their expiration cut in half from 24 months to just 12 months.
So, combining these two, you may want to plan to periodically (twice a year?) transfer a bit of your TYP points to Avianca, rather than transferring everything at once a letting it sit (if you don't have an immediate redemption).
