How The Starwood/Marriott Merger Has Made American Express Membership Rewards Points More Valuable

The link up between Starwood Preferred Guest and Marriott Rewards is great (at least during the current transition!), and has made both SPG Starpoints and Marriott Rewards Points more valuable. This is because you can transfer Points freely between the programmes and therefore benefit from the ‘sweetspots’ of each programme.

For example, there is no Marriott hotel in the world (I’m excluding Edition and Ritz Carlton) that costs more than 15,000 SPG Starpoints per night, because Starpoints now transfer to Marriott at a 1:3 ratio and the top Category Marriott hotels require 45,000 Marriott Rewards Points. This is a stunning deal, particularly when you consider that Starwood can charge more than twice that (up to 35,000 Starpoints) for their own top level hotels.

You can now stay at hotels like the iconic Marriott County Hall for just 15,000 Starpoints!

On the flip side, say you have Marriott Rewards Points and want to use them to stay in Liverpool city centre at the weekend. Before the merger, you’d have to shell out 35,000 Points for the Marriott there, but now you can transfer just 9,000 across to SPG and stay at the Aloft for 3,000 Starpoints!

By redeeming smartly and taking advantage of the best deals each programme has to offer, you can pay less than 50% of the Points you would have had to pay pre-merger for a similar experience.

One of the lesser noticed impacts of the merger though is that it has also (indirectly) substantially increased the value of American Express Membership Rewards Points.


Amex MR Points have always been extremely useful, and I feel that a lot of people ‘waste’ them by automatically transferring to Avios without really considering the other options (Singapore Airlines Krisflyer has some brilliant redemption options for example, as does Etihad Guest etc, etc, etc). Fundamentally, it’s their flexibility that makes them valuable and the SPG/Marriott merger has increased that flexibility further.

Amex MR Points transfer to SPG Starpoints at a rate of 2:1 (so you need to transfer 2 MR Points to get 1 Starpoint), which means they also now transfer to Marriott Rewards at an effective rate of 1:1.5 (1 Amex MR Point gets you 1.5 Marriott Rewards Points). You just need to transfer to SPG first and then across to Marriott from there.

This is a big deal, because until now it’s been difficult to acquire Marriott Rewards Points in significant quantities from the UK unless you stay a lot at Marriott hotels – and that opens up a huge range of new hotel redemption options (even pre-merger, Marriott had the best part of 5,000 hotels!).

It also means that Amex MR Points now transfer (directly or indirectly) to Hilton, Club Carlson, IHG (via Virgin Flying Club), SPG and Marriott, at varying rates of generosity. Therefore, wherever you are travelling, you can look to see which hotel programme has the best value award prices and take advantage (Awardmapper is useful tool for searching, though not perfect).

The merger also means that you can now transfer Amex MR Points to United Mileage Plus Miles at a decent rate.

Historically this has been a problem because SPG’s transfer rate to United is relatively poor (1000 Starpoints only get you 500 Mileage Plus Miles, rather than 1,000 Miles with pretty much any other programme), but United is Marriott’s most generous airline transfer partner.

At the standard rate, 50,000 United Miles requires 112,000 Marriott rewards Points, which is 37,334 Starpoints or 74,667 Amex MR Points. In other words, you can now get 1 United Mile for roughly 1.5 Amex MR Points.

In reality, you can actually do considerably better if you time your transfers to coincide with regular 25% bonuses like the current one, and/or have enough Points to take advantage of Marriott’s ‘Flight + Hotel’ Packages.

270,000 Marriott Rewards Points can currently get you 7 nights at a Category 1-5 hotel + 152,000 United Mileage Plus Miles.

270,000 Marriott Rewards Points is 180,000 Amex MR Points (90,000 Starpoints), which means the transfer rate is about 1.18 Amex MR Points for 1 United Mileage Plus Mile – even if you value the 7 night hotel stay as zero!

I’ll be exploring this (and maybe a couple more of the best new Amex MR transfer opportunities) in detail very soon!

    Some good points Joe here.
    Is there any other hotel or flying partners that you can convert over to Marriott, ive taken a quick look but could not find a lot of info.
    Im looking for advise of what eventually ends up at SPG, so can be one hotel award, transfered to another to then Marriott if needed.

      Cheers! I can’t think of anything off the top of my head unfortunately, but I am very far from being a Marriott expert.
