Extra Bonus on buying Avianca TACA LifeMiles during the 100% Bonus Period (Targeted, YMMV)

Back on April 8th I showcased the latest version of Avianca TACA LifeMiles' 100% Buy Miles promotion and now there is a targeted offer floating around adding extra miles on top for those who have not been active with their accounts in the past 12 months.

The offer I got in my email:

It looks like LoyaltyLobby got it as well and John points out that you can take the targeted link from the email
https://www.lifemiles.com/eng/mya/prt/myaprtone.aspx?id=1&action=oto&codpro=LMAB06&ftnum=Numberhere
and replace Numberhere with your LifeMiles number to register for the offer. There is no guarantee that this will work and that you'll get the extra bonus miles but if you were contemplating buying LifeMiles before the end of the month to take advantage of this great offer it doesn't hurt to try to get the extra little bit of miles

It appears that using the method of adding your LifeMiles # to the URL does not work. LifeMiles definitely worked this one good to ensure only those targeted would get it.
