Maximise your Avios, air miles and hotel points

10% bonus on Starwood transfers to Avios points – is it worth it?

Every nine months or so, British Airways runs a co-ordinated promotion among all of the major hotel chains, offering a bonus of 25% for converting your points to Avios.

The last UK outing for this deal was in June.  Surprisingly, though, Starwood Preferred Guest – the loyalty scheme for Sheraton, Westin, W, St Regis etc – was not included this time.

Whatever the reason, British Airways and Starwood are making up for it by running a dedicated Starwood transfer bonus.

Starwood Avios bonus

You will receive a 10% bonus when you transfer your Starwood Preferred Guest points to Avios before 30th September.  This is the date by which you must initiate the transfer – it does not matter how long the points take to reach British Airways.

The standard transfer rate from SPG to Avios is 1:1.  In addition, when you transfer 20,000 SPG points in one go, you will receive an additional 5,000 miles.

With this promotion, a transfer of 10,000 SPG points will get you 11,000 Avios.  A transfer of 20,000 SPG points will get you 27,500 Avios.

Is this worth it?

‘It depends’ is the boring answer.  It certainly isn’t a terrible deal but you would still be marginally better off redeeming the points for hotel stays if you chose wisely.

Starwood is unique among the hotel schemes in making luxury redemptions very poor value.  Their top properties are 30,000 SPG points per night – not very tempting when the alternative would be to convert to 35,000 Avios points (38,500 under this promotion)!

The sweet spot is generally in the ‘high end but not super-luxe’ market.  Being a bit sad I have a spreadsheet of recent redemptions.  I apparently got 1.6p per point for a recent redemption in Hamburg (Le Meridien at 10,000 points per night), 1.7p for my stay at the Westin Dublin this Summer (12,000 points) and 1.7p for a night booked in Toronto for next year.

Let’s assume you can easily get 1.7p of value per SPG point from a hotel stay.

Let’s also assume that you value an Avios point at 1p.  If you converted 20,000 SPG points, you would receive 25,000 Avios plus a 2,500 Avios bonus, for a total of 27,500.  That means you are effectively getting 1.38p of value per SPG point by converting to Avios.

You will therefore be a little worse off by converting to Avios.  However, if you don’t actually have a plan to use your SPG points for a stay – or don’t have enough to redeem for a free night – this is as a good an opportunity as you are likely to get for the foreseeable future to convert.

Remember that Gold members must convert at least 1,500 points.  Base level members must convert at least 2,500 points.


It seems that only a subset of British Airways Executive Club members were emailed about this offer.  The terms and conditions do NOT say that it is restricted, although the details are not (yet?) on  I feel safe saying that anyone who converts will get the bonus.

    I was hoping for a 25% again, but i will pass on this.
    I keep SPG as Jolly for AA/Lufthansa but having a good balance, I am now starting to think of hotel redemptions in US as I found some nice options and my Avios balance is good.Flexibility is more important for me.

    I take it the bonus 10% will show on the BA side? My Starwood account only showed the 5000 bonus!

  • Stuart Ross says:

    Booked a great deal at The Phoenician, an SPG Luxury Collection Resort, in Scottsdale, Arizona. Five nights in late April for 48,000 points against a £400 per night room. Works out better than 5p per point. Westin at Lake Las Vegas is also great for a cheap weekend night for 7,000 points.

    Can confirm this works for people that didn’t receive the email.

    I received the email, but I’ve only got around 1000 points in my account so below the minimum transfer.

    Wife did not receive the email, but transferred out her remaining 2515 points, and 2766 have moved across 🙂

    We would have been unlikely to use any of our remaining points so better than nothing! 🙂 – though looks like I’ll be stuck with my last 1000 🙁

      “though looks like I’ll be stuck with my last 1000”

      Too late now but you could have transfered your SPG points to your wifes account prior to converting them. (The T&Cs state, Transfers are allowed between SPG members sharing the same address.)

        Yes, indeed – one of the big advantages of the SPG scheme. Particularly useful when you and your other half are taking advantage of sign-up bonuses – you can pool your points for a very decent pot.

      • AndyGWP says:

        DOH! ah well 🙂

        at least I will know, if i need to know again! 🙂
