25% discount when you buy SPG points – a way of buying cheap(ish) airline miles

Starwood is (again) offering a 10%-25% discount when you purchase SPG Starpoints before 31st May. The link to buy is here.

The discount is staggered. You get 10% off purchases of up to 9500 points, 15% off 10000 to 14500, 20% off 15000 to 19500 and the full 25% off only when you buy 20,000 points.

At the top end, 20,000 points will cost you $525 (£350). These can be converted in 25,000 airline miles in the majority of programmes. The price per mile works out at 1.4p, which is certainly not a bargain but less than a lot of airlines charge for buying their miles directly.

£350 would also get you the 20,000 points you need to get a pair of tickets for the SPG Suite at the O2 which I reviewed last week.  This may be a decent deal for a sold out concert although it is obviously pricey.

The rules are straightforward – points post within 24 hours, maximum purchase of 20,000 points per year, your SPG account must be 14 days old to participate.

The ‘sweet spot’ with Starwood was historically their ‘cash and points awards’ for mid-tier properties. Starwood ‘cash and points’ deals were ‘enhanced’ in 2013 and offer poorer value than they did, albeit that they are now available at a wider range of properties.

If you are interested, you can buy via this link.
