It may take up to 24 hours to get the bonus miles which are being offered by Lifemiles rather than Amex.
Exact end time is March 28th, 2026 (11:59 PM GMT-6).
Details of the transfer bonus are here on the Lifemiles website. The bonus is being solely offered by Lifemiles and therefore you will not see the offer on the American Express website.
That said, I do not think many of you should be taking advantage of this offer.
Avianca is a Star Alliance partner that does not pass along fuel surcharges, however:
Keep in mind that Avianca devalued their program in 2024.

With frequent website issues, terrible customer support, and change/cancel fees of up to $200 a ticket, it’s just not for me.
At a mere 15%, I cannot see a case for the transfer unless you were literally about to make a Lifemiles booking anyway.
