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 February 28th, 2025 (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 almost anyone should be taking advantage of this offer.
As I said on the 1st, when Bilt was offering up to a huge 100% transfer bonus:
Avianca is a Star Alliance partner that does not pass along fuel surcharges, however:
Keep in mind that Avianca recently devalued their program.
Also see: Downsides of the LifeMiles program.
With frequent website issues, terrible customer support, and change/cancel fees of up to $200 a ticket, it’s just not for me.
Unlike the Bilt offer, with this offer a mere 15%, I cannot see a case for the transfer unless you were literally about to make a Lifemiles booking anyway.
