The Amex Singapore Airlines suite of credit cards come in four varieties, this article is only looking at the entry-level Amex SIA KF (blue) card.

All 4 Cards

Annual fee

The annual fee for the Amex SIA KF card is $176.55, though the fee is waived for the first membership year.

Fee waiver in subsequent membership years is on request, with most cardholders reporting success when requesting this.


Sign-up bonus

The current sign-up bonus for new Amex cardholders in Singapore for the Amex SIA KF card is up to 21,000 miles, subject to successful approval by 30th September 2020 and made up of the following components:

  • 5,000 miles on first spend.*
  • 8,000 bonus miles if a minimum of $4,000 is spent in the first three months from card approval.
  • 8,000 bonus miles if a further $4,000 is spent in months 4 to 6 (i.e. the subsequent three-month period) from card approval. (New to Amex cardholders only)

* The 5,000 miles welcome bonus is only applicable to first time applicants for any co-branded American Express Singapore Airlines credit card.

For example if your card is approved on 1st April 2020, you’ll have to achieve $5,000 spend between 1st April and 30th June for the first 8,000 bonus, then replicate that minimum spend between 1st July and 30th September for the second bonus.

Note that the second tranche of bonus miles in months 4 to 6 is only applicable if you are new to Amex cards.

Bonus miles are awarded up to 10 weeks after each spend threshold is reached, so in the above example of a card approved on 1st April the latest you’ll be credited with the first bonus is 8th September and the second bonus is 9th December.

As we value KrisFlyer miles at 1.9 cents each, those 21,000 miles are worth at least $400 against future redemptions, so provided you have a $10,000 spend to make over the next six months this card a is a worthwhile addition. Just be prepared to cancel before the end of the first year, otherwise the annual fee kicks in (unless you can have it waived), and there is no recurring bonus.


Earning rates

The Amex SIA KF earns 1.1 miles for every $1 spent both locally (i.e. transacted in SGD) and overseas (i.e. transacted in foreign currency).

The overseas earning rate is boosted to 2 miles for every $1 spent during the months of June and December.

Supplementary card bonus

If you successfully apply for a supplementary card before 30th April 2020 you will receive 1,500 bonus KrisFlyer miles for each of the first two approved supplementary cards (i.e. capped at 3,000 bonus KrisFlyer miles for each basic card member).

The supplementary card bonus KrisFlyer miles will be awarded to basic card members within 10 weeks from approval date of each supplementary card.

Each supplementary card has a $53.50 annual fee, however like the primary card it is waived for the first year.


Are KrisFlyer miles credited directly?

Yes. As these are Singapore Airlines’ own branded cards the miles accrued are automatically transferred to your KrisFlyer account at each monthly statement.

Is there a transfer cost to KrisFlyer miles?

No. Unlike most other credit cards in Singapore, because these miles are transferred automatically each month, there is no additional fee involved.

When do miles transfer to KrisFlyer?

Transfers occur on the first day of each statement cycle, for the qualifying spend accrued in the previous period.

For example if your billing period is 19/02/2020 to 18/03/2020, miles earned during that period will be credited to your KrisFlyer account on 19/03/2020.

Intermediate transfers are not supported, so for example trying to top up your balance quickly using the miles from a large purchase won’t necessarily work if you’ve just missed the end of a statement period – you’ll have to wait around a month for them to post in that case.

Miles rounding

Only full miles are awarded, so a fraction of a mile is rounded up from (and including) 0.5 miles and rounded down if it is less than 0.5 miles. For example:

  • $13 local purchase x 1.1 = 14.3 miles (rounded down to 14 miles)
  • $15 local purchase x 1.1 = 16.5 miles (rounded up to 17 miles)

Minimum spend to earn miles

Due to the rounding policy, the minimum spend to earn miles using this card is:

  • $0.46 at the 1.1 mpd earn rate (rounds up to 1 mile)
  • $0.25 at the 2 mpd earn rate (rounds up to 1 mile)

Forex fee / cpm overseas

The Amex Singapore Airlines KrisFlyer card has a 2.95% foreign currency transaction fee, an increase on the 2.5% rate which applied until March 2020.

With a relatively mundane bonus overseas earn rate of 2 miles per dollar, it’s certainly not the best card to use as it means paying 1.57 cents per mile when spending in foreign currency during the months of June and December.

Worse still, if you use the card for overseas spend during the other 10 months of the year when a 1.1 cents per mile rate applies you’re effectively paying an eye-watering 2.86 cents per mile for the privilege – way over the odds and therefore to be strictly avoided.

There are better cards for overseas spend even at the bonus rate, and you should be looking at the BOC Elite Miles or Standard Chartered Visa Infinite for much better value, not just in cost per mile terms but miles per dollar too.

That said during June and December the bonus rate does mean this card gives you a better cost per mile than the popular Citi PremierMiles and DBS Altitude cards.

* For the Standard Chartered Visa Infinite card, a minimum of $2,000 spend in any currency during the same statement period is required to earn 3 miles per dollar on all FCY spend that month.

Cost per mile also accounts for an additional 0.3% ‘spread’ over money changer currency rates, though this doesn’t apply to all banks and all foreign currencies, so is a worst-case scenario.

Can I transfer miles into other loyalty schemes?

No. Singapore Airlines KrisFlyer is the sole partner with this card and you can only accrue miles in this scheme.

That’s a drawback because with the exception of OCBC and Standard Chartered, all other card providers in Singapore allow transfer into Asia Miles opening up a host of oneworld partner redemptions.

See our guide to where you can transfer your Singapore credit card points here

It certainly doesn’t come close to the range of FFP partners linked to Citi cards, with 11 airline and one hotel loyalty scheme offered as transfer options.

How much is a KrisFlyer mile worth?

In our latest analysis, we value KrisFlyer miles at 1.9 Singapore cents each. That’s our upper limit to buy, based on our typical redemption profile (First and Business Class saver award seats throughout the year).

Even then, this is a pessimistic level. We actually achieve an average of 2.4 cents per mile value when redeeming, against some fairly strict valuation criteria.

For example we don’t value 94,000 KrisFlyer miles on a return flight from Singapore to Tokyo in Business Class at the price Singapore Airlines is charging for those flights ($3,100, i.e. 3.3 cents per mile) because Malaysia Airlines is offering a Business Class option via Kuala Lumpur for $2,300.

Do KrisFlyer miles expire?

Yes, and that’s a drawback of any co-brand credit card like this one where your accrued miles will be transferred into your KrisFlyer account each month.

KrisFlyer miles expire three years after the month in which they were earned, so for example miles credited to your account from this credit card in April 2020 will expire at midnight on 30th April 2023. Miles credited in May 2020 will expire at midnight on 31st May 2020, and so on.

With many credit cards there is the option to keep your points accumulated at the bank side for at least two years before they expire, then transfer into KrisFlyer for a further three years validity.


0% interest instalments on SIA tickets

American Express offers its ‘Pay Small’ program with a variety of merchants, allowing you to break down larger transactions into 6, 12 or 24-month payments at 0% interest but forgoing any rewards (i.e. KrisFlyer miles with this card) in the process.

Pay Small Logo

That’s not really of interest to most of our readers who will be using this card to help maximise their annual KrisFlyer miles accrual.

Pay Small can be used however to purchase Singapore Airlines tickets and still earn 0.5 KrisFlyer miles per $1 spent, with no cap. The following rules apply:

  • Only applicable under the 6-month instalment option
  • Charge of $250 or more
  • Purchase must be made at
  • Travel must originate in Singapore and payment must be made in Singapore dollars.

To use Pay Small at, you must select the option ‘American Express: 0% interest* 6-month instalment plan with Pay Small’ during the checkout process.

For example, a $4,926.80 Business Class return ticket to London can be converted into six interest-free instalments of $821.13.

Pay Small

You must pay your card account in full each month to use the Pay Small 0% interest option.

Remember of course that this card usually earns 2 miles per dollar on transactions at, so you are forfeiting the majority of your miles earning potential by using the Pay Small facility.

In the above example you’ll accrue 2,463 miles instead of the usual 9,852 miles paying upfront.

$150 cashback on SIA tickets

When you spend $12,000 on eligible purchases with your Amex Singapore Airlines KrisFlyer card from 1 July 2019 to 30 June 2020, you’ll receive a $150 credit on your next purchase of Singapore Airlines tickets at

This will be credited directly to your card account as a $150 statement credit after your eligible Singapore Airlines ticket purchase on is completed and is only valid for 12 months from the date you meet the $12,000 spend criteria.

Eligible ticket purchases are for travel originating from Singapore only and must be purchased in Singapore Dollars. It cannot be used to offset purchases of SilkAir tickets, and must be fully utilised in a single transaction.

The statement credit should appear on your bill within 90 days from date of your eligible Singapore Airlines ticket purchase.


Other benefits

As a relatively low (or no) fee card, Amex SIA KF isn’t showered with additional benefits but some of the key ones which will be of most interest to our readers are:

  • 2 miles per $1 spent on eligible purchases made on, SingaporeAir mobile app, and KrisShop (in-flight and online), with no cap.
  • 3.1 miles per $1 spent on your ‘daily essentials’ at the following participating merchants: Deliveroo, foodpanda, McDonald’s, SISTIC, Starbucks, Subway, The Coffee Bean & Tea Leaf, Unity and Watsons, capped at $200 spend in each calendar month. Details here.
  • 3.1 miles per $1 spent on Grab rides, capped at $200 spend each calendar month. Details here.
  • 500 miles for your first Grab booking when you set your American Express Singapore Airlines Credit Card as the default payment card (expires 31st December 2020). Details here.
  • Hertz Gold Plus Rewards benefits.
  • 7% discount on ChangiWiFi overseas Wi-Fi router rental (see T&Cs page 11 for discount codes).
  • American Express Selects travel, shopping, dining and entertainment discounts.
  • Card promotions including discounts at, Expedia etc…

Our summary

The Amex SIA KF card is a basic miles earning option, with an attractive sign-up bonus and low income requirement, however ongoing miles-earning rates for general spend are poor and the overseas bonus earn rate is strangely complicated as it only applies for two months of the year.

On the other had there are attractive offers through the year with this card, the Grab ride earn rate is competitive and our experience is that American Express has the best customer service in Singapore.

While 2 miles per $1 spent at Singapore Airlines is a nice addition, the DBS Altitude (review here) boasts 3 miles per $1 in this category, and also includes a few other useful airlines like Cathay Pacific and Qatar Airways.

We would suggest the Citi PremierMiles (review here) or UOB PRVI Miles (review herecards instead, especially Citi for the more attractive sign-up bonus usually on offer and the wide range of airline transfer partners.

That said, this remains a good card with a few nice perks, and a fee-free option in year one which makes the sign-up bonus very competitive. The automatic miles conversion into KrisFlyer each month also makes this a simple card for many people who don’t want to keep on top of the transfer process.

  1. Dont take American Express credit card in Singapore, Bad experience with the customer service – Amy. Moreover, the annual fee unable to be waived unless other banks DBS or OCBC. Already cut the card and will not apply again. Not advisable.
