Iberia Plus continues celebrating its 25th anniversary with yet another promo.
This time the promo is targeted to their American Express Spain cardholders, offering a 25% Avios bonus for Membership Rewards points transfers.
From the promo terms & conditions (google translate):
* Promotion valid for American Express Holders enrolled in the Membership Rewards® Club program, with Cards issued by American Express Card España S.A.U. Or Bansamex S.A. Transfer your MR points to your Iberia Plus program from August 22 to September 30, 2017. For each transfer of MR points on these dates you will receive an additional 25% of Avios in your Iberia Plus program. Promotional Avios will be paid in your Iberia Plus program within a maximum period of 10 working days once you receive the transfer of MR points to your Iberia Plus program. 1 MR point equals 1 Avios. See the general conditions of the Membership Rewards® Club program at americanexpress.es/mrclub.
This is not the most generous transfer bonus I have seen, as there have been 30 to 50% transfer bonuses before, but it’s always better than nothing!
