How to get a 35% bonus on your Membership Rewards balance – but why it isn’t always a great idea

Links on Head for Points may pay us an affiliate commission. A list of partners is here.

One of the downsides of the fall of Sterling against the Dollar and the Euro since the Brexit vote has been to destroy much – but not all – of the generous arbitrage that used to be available if you held the American Express International Dollar Card.

In the past with Sterling at $1.60, you could use this to get a 60% bonus on your existing UK Membership Rewards balance.  This is especially interesting if you have thought about booking a Singapore Airlines redemption (either on Singapore Airlines or a Star Alliance partner such as Lufthansa or SWISS) because it reduces the cost substantially.

The fall in the US$ to 1.35 to the £1 means that this option is less exciting than it was as you are now only getting a 35% bonus.  There are still reasons for doing it which I will discuss below.

Please note this is ‘PhD level’ points collecting.  It is unsuitable for anyone with an Amex Membership Rewards balance of under 50,000 points and/or no experience of airline programmes apart from Avios.

Let me explain in simple terms how you can benefit from this:

Amex Green

Amex issues from the UK an International Dollar Card. They come in Green, Gold and Platinum.   For the purposes of this discussion we are only interested in the Green card which has an annual fee of $100 and an additional $36 annual fee to access Membership Rewards (free in year one).

This card bills in US$ and you must pay the bill in US$ by bank transfer.  Most UK online banking systems can handle this – I do it via HSBC with no problems.  

As a US$ card, any Sterling transactions you make on it are hit with a 3% FX fee plus you have to pay whatever charges your bank makes for transferring money to Amex in $ to pay your bill.  This means there is no point getting this card for general day to day spending due to the FX fees unless you have a US$ bank account and spend a lot of money in the US

However, once you have the card, you can transfer your UK Membership Rewards balance to your IDC card Membership Rewards account. Your balance is grossed up by the £/$ exchange rate, so currently you get 1.35x your UK balance.  100,000 UK MR points will turn into 135,000 points in your IDC MR account.

You are only allowed one transfer from the UK to IDC scheme every 12 months (rolling 12 months)

However, most Membership Rewards products for IDC cardholders are more expensive (see here). Avios transfers are 3:2 instead of 1:1 from the UK scheme.  This makes it pointless as you would actually end up worse off.

However, a number of airlines – including Singapore Airlines – allow 1:1 transfers, so you are effectively getting a 35% bonus on transferring to them.

There are also partners in the IDC Membership Rewards programme who are not in the UK programme.  These include Malaysia Airlines, Qatar Airways and Jumeirah Hotels.

In order to apply for an IDC card, you must have been an existing American Express cardholder for at least six months.

How can I benefit from this?

Here is the Membership Rewards online catalogue for the IDC Amex cards.

The following airline partners let you transfer 1:1 from the IDC Membership Rewards programme into your airline account. This means (because of the 35% uplift – based on £1=$1.35 – when you move your points from the UK to IDC MR programmes) you effectively get a 35% transfer bonus.

  • Alitalia (SkyTeam)
  • Cathay Pacific Asia Miles (oneworld)
  • Finnair Plus (oneworld)
  • Malaysia Airlines Enrich (oneworld) (Malaysia is not in the UK scheme at all)
  • Singapore Airlines KrisFlyer (Star Alliance)

The following airlines and hotels are also IDC Membership Rewards partners but are NOT worth transferring to because they have adjusted their transfer rate compared to the UK scheme:

  • Avios (BA and Iberia) 3:2 (UK scheme 1:1)
  • Delta Skymiles 3:2 (UK scheme 1:1)
  • Emirates Skywards 3:2 (UK scheme 1:1)
  • Etihad Guest 3:2 (UK scheme 1:1)
  • Flying Blue 3:2 (UK scheme 1:1)
  • Hilton Honors – 4:5 (UK scheme 1:2)
  • Radisson Rewards 2:3 (UK scheme 1:3)
  • SAS EuroBonus 3:2 (UK scheme 1:1)
  • Starwood Preferred Guest 3:1 (UK scheme 2:1)
  • Virgin Flying Club 3:2 (UK scheme 1:1)

The following are not in the UK scheme but are in the IDC scheme:

  • Jumeirah Sirius – 4:1
  • Qatar Airways Privilege Club – 3:2
  • Malaysia Airlines – 1:1


You should only consider an IDC American Express card if you are interested in moving your Membership Rewards points to Alitalia, Cathay Pacific, Finnair, Singapore Airlines, Malaysia Airlines, Qatar Airways or Jumeirah Hotels.

The first four have attractive 1:1 rates whilst the last three are not UK Amex partners.

Singapore Airlines is likely to be the most popular option because Singapore is SUBSTANTIALLY more generous with award seats for its own members than it is for other Star Alliance partners.

There is also a generous ‘sweet spot’ using Singapore Airlines miles to fly from the UK to the Middle East as I discussed here.  I booked our holiday flights to Dubai this year with Singapore Airlines miles, flying on SWISS via Zurich.  London to Dubai is only 50,000 KrisFlyer miles return in Business Class – compared to 120,000 Avios on a peak date – and because of the uplift I got moving my Amex points from the UK to IDC scheme, the net cost was even less.

I know one of our regular comment contributors recently used this method to fly to Australia in Business Class via a Singapore Airlines redemption.

The good news is that all three major airline alliances are covered, so you can access the bulk of the major global airlines.

You would, of course, have to look carefully at each programme before transferring. You could book a BA flight via Finnair, Cathay or Malaysian, for example, but you would need to pick a route for redemption and then see which carrier needs fewest miles. You also need to consider cancellation and change fees and whether one-way awards are possible.

As I said, this is definitely not something for beginners. If you know what you’re doing, however, there can be real value to be had.

    Can Membership Rewards points be transferred from a UK Amex to a HK issued Amex (or an Amex in another region for example) where the cardholder is the same person?

  2. Good thing you’re not wasting your time with it then. Wouldn’t want it to get in the way of your precious trolling time.

  3. Memesweeper says:

    Can you get a pro-rata refund on the card fee after a few months of membership? Can you transfer IDC -> UK? For instance if you’ve been spending time in the US or Eurozone but now want to go back to a Sterling based MR card? I realise that the points might loose some value in this case.

    • You can move points back (1 move every 12 months in each direction allowed) but you’d lose the uplift.

    “I know one of our regular comment contributors recently used this method to fly to Australia in Business Class via a Singapore Airlines redemption.”
    If we’re thinking of the same person, I thought the majority of the sectors were in Suites? I’m sure he’ll be along soon…

    • Lol hello 😛

      • the real harry1 says:

        @Alan O/T decent BT broadband offer gone live yesterday, headline £22/ month (see mserrrr link) then you drop your application at a late stage on a site we know & love into their BT link to get £90 on top for new customer (if you’re currently on BT anyway, switch the contract to your wife to get new customer status). Works out £17/ month, not as good as my £12.82 but best out there and I did get £60 service recovery so am really paying £16.15/ month, not so different).

        • What website is that Real Harry1?

        • Haha nice, although no wife to swap it to 😉 On a decent deal just now which they’ve continued to honour at least.

    • Matthew says:

      Similar to Alan, I did a pretty big transfer of 280,000 Amex MR to SQ via uplift of 1.6 using IDC card to go business to NZ and back for family of four. Was fab 🙂

  5. Shame the exchange rate has worsened but this was how I have flown two return trips in SQ Suites to NZ for a fraction of the cost using Avios! (and in a much better product)

  6. Can you churn the Platinum MR charge card if you keep the IDC card, or would you need to close both and open both again 6 months later? That is assuming that the churn rule changes that were threatened a while ago don’t happen…

    • I seems like a good place to keep the MR points and churn the Plat MR card if keeping the IDC card is not affecting the sign up bonus.

    • Different MR account so shouldn’t be an issue.

  7. Does it make sense / work to time this when BA/Amex in the US offer 50% bonus transfers from MR?

    “I booked our holiday flights to Dubai this year with Singapore Airlines miles, flying on SWISS via Zurich. London to Dubai is only 50,000 KrisFlyer miles return in Business Class ”

    Rob is the redemption FROM ZRH with a separate flight from LON or are connections allowed with SQ redemptions. I thought SQ redemptions were point to point the same as Avios

  9. Mackle says:

    I am interested in the Euro green ICC.

    I moved to the Eurozone, but have kept my UK BAPP Amex and platinum charge card, as my girlfriend is still UK based so is a supplemental on the BAPP card and my Dad is a supplemental on the Platinum card.

    When I use the either card though, I am hit with a 3% non-sterling transaction fee.

    So the idea of a Euro green card so that I still have the benefits of my UK issued plat, and still get Avios from my girlfriend using my BAPP, whilst avoiding the 3% charge on everything that I spend here, is quite appealing.

  10. Henry says:

    Didn’t you post this article a month or so ago? Currently in the process of transferring point (2 weeks waiting, which apparently is the time it takes)

    • We used bits of it in an article about Singapore Airlines redemptions, yes. We do that sometimes 🙂

  11. Why don’t you have a credit card from a local bank? The 3% fee for spending in GBP is neither here nor there unless your income/savings are entirely in GBP
