I have noticed this promotion pop up before, and it usually only lasts for a day or so. But if you collect American Airlines miles and also stay at Marriott hotels, it really pays to pay attention to these offers…

Many readers will be familiar with cashback websites such as Topcashback and Quidco. You might also be familiar with the e-stores offered by Avios and Virgin Atlantic Flying Club. Not all hotel chains pay affiliate marketing commissions – the commission that gets paid back out to you as cashback or miles – but Marriott does…

For a limited time only, the American Airlines AAdvantage shopping portal is offering 10 miles per US dollar spent with Marriott hotels.

A conservative estimate of the value of an AA mile would be 1.5 US cents, a more aggressive one would be 2 cents. This means that you would receive a 15-20% rebate on your hotel stays, as long as you collect and value AA miles.

You won’t miss any perks by visiting the Marriott website via the AAdvantage shopping portal. You still receive your points, status credit / benefits, etc. So once you start stacking the various promotions and standard earning, you can easily arrive at a 30-40% rebate!

So, if you have any existing, flexible reservations with Marriott, you might want to cancel and re-book via the AA shopping portal. Or, if you have been contemplating a Marriott stay, you might want to book it ASAP. You don’t have to prepay; you simply must book whilst the AA website is showing the 10 mile rate. Your stay can be several months away, although you won’t receive your AA miles until well after check-out. (your biggest risk is losing track of which reservations have paid out their “miles back”)

I probably wouldn’t start collecting AA miles as a result of this promotion, but if you are building up your AA miles balance towards an Etihad First Class reward to/from the UAE/India/Maldives/etc., (long may it last!) then this is a quick and easy way to pick up thousands of miles…
