This is your final reminder that July 29th is the last day to apply for the Starwood American Express card and claim a 20,000 SPG points (=25,000 Avios) sign-up bonus.
Based on historic patterns, I would expect the bonus to drop back to 10,000 points (= 10,000 Avios) after the 29th.
The key point with this card is that you can apply for it whatever other Amex cards you have. There are no restrictions. The only people who cannot apply (assuming you meet the income requirement) are people who have already had this card and cancelled less than 6 months ago.
My full review of the SPG Amex is here. The Amex home page for the SPG card is here.
The sign-up bonus of 20,000 SPG points is a good deal if you redeem for hotel stays at Sheraton, Westin, W, St Regis, Luxury Collection etc. You can also convert 20,000 SPG points into airline miles. The great news here is that 20,000 SPG points is the trigger required to get a 5,000 mile bonus. Whilst the standard bonus of 10,000 SPG points only gets you 10,000 airline miles, when you convert 20,000 you get 20,000 airline miles plus 5,000 extra!
Your 20,000 SPG points sign-up bonus would therefore get you 25,000 airline miles! You can convert to Avios, of course, but also to a lot of other airlines. There are over 30 airline partners in total.
Now, here are the facts on the card:
- 20,000 SPG points when you spend £1,000 within 3 months (£1,000 is a very modest target for such a good deal)
- 1 SPG point per £1 spent going forward
- £75 annual fee, refunded pro-rate if you cancel
- £30,000 household income requirement
- No problem getting the bonus even if you have a BA, Platinum, Gold or any other Amex
Now, the obvious thing to do with Starwood points is to use them for Sheraton, Westin, W, aloft etc hotel stays. Here is the reward chart if you want to see how far 20,000 points will get you. When my wife got this bonus, I redeemed them for a hotel in Greece that got me £370 of value for my sign-up bonus – see here for that story.
For many people, though, they are more valuable as airline miles. This is especially true when you have 20,000 of them – as you will – since Starwood gives you a 5,000 mile bonus when you convert 20,000.
SPG has a huge number of airline partners. 20,000 SPG points will get you:
- 25,000 Avios points
- 25,000 Virgin Flying Club miles
- 25,000 Miles & More miles
- 25,000 miles with Air Canada, airberlin, Air China, Alaska, Alitalia, ANA, American, Asia Miles, Asiana, China Eastern, China Southern, Delta, Emirates, Etihad, Flying Blue, Hawaiian, Japan Airlines, Qatar, Saudi Arabian, Singapore, Thai, US
- 12,500 United miles
- 37,500 LAN LANPASS miles
- 385 Air New Zealand points
The card is especially valuable if you want to generate some miles in one of the airline partner programmes apart from Avios. There aren’t that many easy ways to earn, for example, 25,000 Miles & More or Aeroplan miles from the UK.
If you recently applied for the American Airlines card with the 35,000 miles sign-up bonus, you could use this card to get an additional 25,000 American Airlines miles. You need 50,000 AA miles for a Business Class return one-way ticket from the UK to US, for example, so this is a good way to get the extra.
You also have the option of using your SPG points to book a cash flight. I wrote about the SPG Flights redemptions here. 25,000 SPG points would get you a flight selling for up to £210.
There are two other perks to the Starwood card which are not clearly mentioned on the application form:
- If you cancel, you get a pro-rata refund of your £75 fee
- Starwood points can be transferred – for free – between two members who live at the same address. You can therefore get a card in the name of your partner, move the points to your SPG account and then redeem them into your airline account
