American Express is offering a 40% transfer bonus to British Airways Executive Club now through September 17, 2017. With this bonus, you’ll now receive 350 British Avios per 250 Membership Rewards points.

British Airways has long been a partner of American Express, however, and the last bonus we said was last August, so I’m pleased to hear that one is finally here.

Membership Rewards now transfer to British Airways Avios at 1:1 ratio, meaning 250 Membership Rewards points to 250 Avios, but with this promotion you’ll receive 350 per each 250 Membership Rewards points.

If you are looking for an award where British Airways Avios can be a good use, then consider this 40% transfer bonus from American Express to get more miles from your American Express Membership Rewards points.

If you’re looking for American Express cards to earn Membership Rewards points consider the following:

• The Platinum Card® from American Express 
• Business Green Rewards Card from American Express
• The Business Gold Rewards Card from American Express
• The Business Platinum Card® from American Express
