It took a while, but American Express Membership Rewards is finally offering a transfer bonus! You can now receive a 25% bonus when you transfer Membership Reward points to British Airways Executive Club for Avios points.
The last time we saw an American Express and Avios bonus was from March 1, 2013 to March 31, 2013, but it was a 50% transfer offer. The current offer is valid until September 30, 2015.
Normally you can transfer at a 1:1 ratio at a minimum of 1.000 points. With the promotion the same 1,000 Membership Rewards gets you 1,250 Avios.
I am really happy to see this promotion, not really because it is a good promotion because we have seen 50% transfer bonuses, but because we finally see some signs of life from American Express and one of its transfer partners.
