Click on “Transfer your points to Lifemiles” for the full details.
You can transfer increments of 1,000 Citi ThankYou Points into 1,250 Avianca Lifemiles through 7/5/19. The 25% bonus is added by Lifemiles and will take up to 45 days to post to your account.
You can also earn a 25% bonus with transfers from Hilton, IHG, or Marriott. The only worthwhile option would be from Marriott, where 60K points would transfer into 31,250 Lifemiles after the 25% Marriott bonus for 60K transfers and the 25% Lifemiles bonus.
Note that Avianca Lifemiles require earning activity every 12 months in order to stop your miles from expiring. Transferring points to Lifemiles will extend the points validity for 12 more months.
With this promotion you’ll be able to redeem United award flights from just 6,000 points each way! You can read more about that and all about the Avianca Lifemiles program in this post.
