Earn 12 Bonvoy points per £1 at selected Marriott hotels

The Marriott Bonvoy American Express Card has quietly rolled out a ‘double points’ promotion.

Assuming this is open to all cardholders, you will see it under the ‘Offers’ tab in the Amex app or website. You must opt-in by clicking ‘Save to Card’.

Usually, you earn 6 Marriott Bonvoy points per £1 on the Marriott Bonvoy American Express Card when you pay at participating Marriott Bonvoy hotels. We value Marriott points at 0.5p so this is equivalent to a 3% rebate.

Until 4th September, this is doubled to 12 Marriott Bonvoy points per £1.

Payment must be made by 4th September. Pre-paid bookings made for a later date should trigger the double points, as long as the hotel does actually take the payment in advance, but you can never be 100% certain.

There are participating hotels in Austra, Belgium, France, Germany, Italy, the Netherlands, Spain, Sweden, Switzerland and the UK.

The full list here is here (PDF).
