Roundup: Credit card sign-up bonuses (August 2023)

Here’s The MileLion’s monthly roundup of the latest credit card sign-up bonuses in Singapore for August 2023. 

If you have any big ticket spending coming up, these bonuses could be an opportunity to rack up some extra miles or gifts, so plan your spending accordingly!

💳 Credit Card Sign-Up Bonuses: August 2023

Sign-up bonus summary Sign-up bonuses AMEX HighFlyer Card AMEX KrisFlyer Ascend AMEX Platinum Credit Card AMEX Platinum Charge Citi PremierMiles Card Citi Prestige Card Citi Rewards Card DBS Altitude AMEX DBS Altitude Visa DBS Vantage Card HSBC TravelOne Card KrisFlyer UOB Credit Card StanChart Journey Card UOB PRVI Miles Card My picks Non-miles sign-up bonuses

At a glance: Current sign-up bonuses

Here’s a summary of the current sign-up bonuses on the market, presented two ways: 

1. Payoff ratio
2. Cost per mile

Payoff ratio refers to the bonus miles divided by total spend (excluding annual fee). Basically: what’s the bang for your buck? For every S$1 of spend, how many miles do you get?

On that basis, here are are best sign-up offers. 

💳 Credit Card Sign-Up Bonuses (sorted by payoff ratio)
	Spend (AF)	Miles^	Payoff
Citi Premier Miles	S$800 (S$194)*	30K	37.5
Citi Prestige	S$2K (S$540)	71K	35.5
HSBC TravelOne Card	S$800 (S$194)	20K	25

AMEX Platinum Credit Card	S$3K (S$324)	16.7K	5.6
AMEX Platinum Charge	S$15K (S$1,728)	59.4K	4.0
^Does not include base miles *Fee waiver option available, with smaller number of bonus miles. See below for full details.

Cost per mile refers to the bonus miles divided by annual fee. If you need to pay an annual fee as part of the sign-up bonus, you’re essentially paying for miles- the question is, how much?

On that basis, here are are best sign-up offers.

💳 Credit Card Sign-Up Bonuses (sorted by cost per mile)
	Spend (AF)	Miles^	Cost Per Mile
KrisFlyer UOB	S$2K (FYF)	25K	–
Citi Rewards	S$800 (FYF)	16K	–

AMEX Platinum Charge	S$15K (S$1,728)	59.4	2.90
^Does not include base miles *Fee waiver option available, with smaller number of bonus miles. See below for full details.

Ultimately, both sets of ranking criteria have a common shortcoming: they only look at miles. Some of these cards have additional benefits like free hotel nights or airport lounge access, which you’ll also need to factor into your decision.

For instance, the AMEX Platinum Charge has the highest cost per mile at 2.90 cents apiece, and indeed, if miles were the only benefit, you’d be silly to pay that price. But you need to factor in the value of other perks like unlimited lounge visits, free hotel stays, S$1,354 of annual statement credits, dining vouchers etc.

Therefore, it’s always advisable to read through each of the sign-up bonus articles and The MileLion’s Card Reviews before coming to a decision.

AMEX HighFlyer Card

AMEX HighFlyer Card (Offer Ends: 3 Oct 23)
Apply
Details
	New & Existing
Annual Fee	S$301.80 (must be paid)
Spend	S$4,000 (day 1-90) S$4,000 (day 91-180)
Spend Period	180 days
Base Miles	14,400
Bonus Miles	60,000
Total Miles	74,400
Applicants who have cancelled the AMEX HighFlyer Card previously for the same company are not eligible.

New AMEX HighFlyer Cardholders who submit their applications by 3 October 2023 (with approval by 31 December 2023) will receive:

• 30,000 HighFlyer points with a minimum spend of S$4,000 between days 1-90 after approval
• 30,000 HighFlyer points with a minimum spend of S$4,000 between days 91-180 after approval

Alternatively, they can opt to spend S$5,000 in days 1-90 and receive a Samsonite Choca Spinner 68/25 luggage. 

On top of the bonus HighFlyer points or luggage, they’ll earn 14,400 HighFlyer points for spending S$8,000 (based on 1.8 HighFlyer points per S$1).

The S$301.80 annual fee must be paid. There is no requirement that you be new-to-AMEX; the offer applies even if you hold an existing AMEX consumer card. Applicants who have cancelled the AMEX HighFlyer Card previously for the same company are not eligible. 

Unfortunately, there’s no more first year fee waiver option available for the AMEX HighFlyer Card, and this card no longer earns miles on GrabPay top-ups.

That said, the AMEX HighFlyer Card does come with a complimentary Accor Plus Explorer membership with a 1-night hotel stay and up to 50% off dining. If you’re interested in this, then the AMEX HighFlyer Card’s S$301.80 annual fee represents a ~30% discount to the usual retail price of S$418.

New customers are defined as those who do not currently hold a principal AMEX consumer card (DBS, Citi and UOB-issued AMEX cards do not count, nor does the AMEX HighFlyer Card) and have not cancelled an AMEX KrisFlyer Ascend Card in the past 12 months

New-to-bank customers who sign up for an AMEX KrisFlyer Ascend Card by 31 August 2023 (with approval by 14 September 2023) will enjoy 31,200 bonus miles when they pay the S$340.20 annual fee and spend S$1,500 within 30 days of approval. Assuming you clock the minimum spend on local transactions, you’ll earn a further 1,800 base miles (S$1,000 @ 1.2 mpd).

Do note that the calculations assume that this is your first-ever American Express Singapore Airlines cobrand card. If you have held one in the past, you need to deduct 5,000 miles from the bonus component. 

While the first year’s annual fee cannot be waived, you’ll receive a complimentary one night stay at participating Hilton properties, Hilton Silver status (which saves you the 5th night off redemptions), and four complimentary lounge passes.

Assuming you clock the minimum spend on local transactions, you’ll earn a further 18,750 base MR points (11,719 miles). 

Existing customers who sign up for an AMEX Platinum Charge by 14 August 2023 (with approval by 28 August 2023) will enjoy 70,000 bonus MR points (43,750 miles) when they pay the S$1,728 annual fee and spend S$10,000 within 90 days of approval. Assuming you clock the minimum spend on local transactions, you’ll earn a further 12,500 base MR points (7,813 miles). 

AMEX Platinum Charge cardholders will be able to enjoy two sets of the newly-launched S$1,354 statement credits in their first year, since these are awarded based on calendar year instead of membership year. These are valid for fashion, dining, lifestyle, air travel and entertainment; refer to the article below for more details.

Citi PremierMiles Card

Annual Fee	S$194.40 (must be paid)	Waived

Spend Period	2-3 months	2-3 months
Base Miles	960	960
Bonus Miles	30,000	8,000
Total Miles	30,960	8,960
New customers are defined as those who do not currently hold a principal Citi credit card, and have not cancelled one in the past 12 months

New-to-bank customers have a choice of two offers for the Citi PremierMiles Card. 

They can earn 30,000 bonus miles when they pay the S$194.40 annual fee and spend S$800 within 2-3 months of approval (the exact timeframe depends on when approval comes through; you have until the end of the second month after the approval month to spend). Assuming you clock the minimum spend on local transactions, you’ll earn a further 960 base miles (S$800 @ 1.2 mpd).

Alternatively, they can earn 8,000 bonus miles when they spend S$800 within 2-3 months of approval, together with an annual fee waiver. Assuming you clock the minimum spend on local transactions, you’ll earn a further 960 base miles (S$800 @ 1.2 mpd).

Is it worth paying S$194.40 for the opportunity to pick up 22,000 more miles? I’d say yes, since that works out to 0.88 cents per mile, and the spending requirement is the same.

Citi Prestige Card

Citi Prestige Card (Offer Ends: 31 Oct 23)
Apply
Details
	New & Existing
Annual Fee	S$540 (must be paid)
Spend	S$1,000 in SGD S$1,000 in FCY
Spend Period	2-3 months
Base Miles	3,300
Bonus Miles	71,000
Total Miles	74,300
Offer valid for anyone who has not cancelled a Citi Prestige Card in the past 12 months

This month, the Citi Prestige Card has upsized its sign-up bonus to 71,000 bonus miles for cardholders who:

• Pay the S$540 annual fee (25,000 miles)
• Spend S$1,000 in local currency (23,000 miles)
• Spend S$1,000 in foreign currency (23,000 miles)

The minimum spend for local and foreign currency must be made within 2-3 months of approval (the exact timeframe depends on when approval comes through; you have until the end of the second month after the approval month to spend).

Assuming you meet both the local and foreign currency spending goals, you’ll earn a further 3,300 base miles (S$1,000 @ 1.3 mpd + S$1,000 @ 2 mpd).

What’s noteworthy about this offer is that it’s available to existing Citi cardholders as well, so holding a Citi PremierMiles Card or Citi Rewards Card won’t disqualify you from taking part. As this is the most generous sign-up offer for the Citi Prestige Card we’ve seen in a long while, I’d highly recommend jumping onboard. 

Citi Rewards Card

Total Miles	19,200
New customers are defined as those who do not currently hold a principal Citi credit card, and have not cancelled one in the past 12 months

New-to-bank customers can earn 16,000 bonus miles when they spend S$800 within 2-3 months of approval (the exact timeframe depends on when approval comes through; you have until the end of the second month after the approval month to spend). The first year’s annual fee is waived. 

Assuming you clock the minimum spend on online transactions (and you should, given how easy it is), you’ll earn a further 3,200 base miles (S$800 @ 4 mpd).

I consider the Citi Rewards Card to be practically essential for miles collectors, and if you don’t have one for whatever reason, that’s something you need to change.

Do note that we periodically see the Vantage Card’s sign-up offer upsized to 80,000/60,000 bonus miles for new-to-bank/existing customers, so if you can wait, I’d recommend holding out for that offer to return.

The newly-launched HSBC TravelOne Card, which is offering 20,000  bonus miles to both new and existing customers who:

• Pay the annual fee of S$194.40
• Spend at least S$800 during the qualifying spending period
• Opt-in for marketing communications during the sign-up process

The qualifying spending period is as follows:

Card Account Opening Date	Qualifying Spend Period
11-31 May 2023	11 May to 30 Jun 2023
1-30 Jun 2023	1 Jun to 31 Jul 2023

New customers are defined as those who do not currently hold a principal UOB credit card, and have not cancelled one in the past 6 months

What’s this? An uncapped UOB sign-up bonus? Surely this must be a glitch in the Matrix!

Apparently not. New-to-bank customers who apply for a KrisFlyer UOB Credit Card will enjoy 25,000 bonus miles when they spend at least S$2,000 in the first 60 days. The first year’s annual fee is waived.

Assuming you clock the minimum spend on local transactions, you’ll earn a further 2,400 base miles (S$2,000 @ 1.2 mpd).

I’ve made no secret of my issues with the KrisFlyer UOB Credit Card, but when it’s all said and done, this is a card that offers an uncapped 3 mpd on SIA and Scoot tickets, Kris+, dining, online shopping and travel, and transport. If you’ve maxed out your 4 mpd allowances, or god forbid are part of the “one card” camp, then this would be the next best alternative.

New customers are defined as those who do not currently hold a principal StanChart credit card, and have not cancelled one in the past 12 months

New this month is an improved offer for the StanChart Journey Card, where new-to-bank customers will receive 35,000 bonus miles for spending S$3,000 in the first 60 days of approval. They can also choose to pay the first year’s S$194.40 annual fee for an extra 10,000 bonus miles.

Assuming the S$3,000 is spent in local currency, cardholders will earn an additional 3,600 base miles (S$3,000 @ 1.2 mpd). 

If you have plans to head overseas for the year-end holidays, my advice would be to apply for this card around mid-September, then clock your minimum spend in overseas transactions. You’ll earn 2 mpd with a rebate of the usual 3.5% FCY transaction fee, courtesy of StanChart’s year end FCY spending promo for November and December 2022.

New customers are defined as those who do not currently hold a principal UOB credit card, and have not cancelled a principal UOB credit card in the past 6 months prior to 1 May 2023

New-to-bank UOB PRVI Miles Cardmembers who apply and get approved from 1-31 August 2023 will enjoy up to 45,200 bonus miles, split into:

• 20,000 miles for paying the S$259.20 annual fee
• 25,200 miles for spending S$1,000 per month for two consecutive months

There is no cap on the maximum customers eligible for either component. Repeat: there is no cap. However, do note that you must be approved by 31 August 2023, so don’t leave your application till the last minute. 

Assuming the S$2,000 minimum spend is clocked locally, a further 2,800 base miles (S$2,000 @ 1.4 mpd) will be earned. If the minimum spend is clocked overseas, a further 4,800 (S$2,000 @ 2.4 mpd) base miles will be earned. UOB assumes the latter scenario in its marketing, which is why you’ll see claims of a 50,000 miles sign-up bonus (45,200 bonus + 4,800 base) on its website.

Since the first-year annual fee is waived by default, cardholders must opt in by sending the following SMS to 77862 by 30 September 2023.

📱 SMS to 77862

PMAF<space>Last 4 alphanumeric digits of NRIC/Passport (Example: If your NRIC is S1234567A, send “PMAF 567A”)

My picks

Both the KrisFlyer UOB Credit Card and Citi Rewards Card offer a waiver of the first year’s annual fee, so provided you can meet the minimum spend, then it’s basically free miles. 

I’d also recommend considering the brand new HSBC TravelOne Card because the sign-up offer is valid for existing HSBC customers as well. But remember: if you’re new to HSBC, remember that you should apply for a HSBC Revolution first, in order to get the S$150 cashback offer! You can then apply for the TravelOne as an existing HSBC customer and enjoy the same bonus.

The upsized Citi Prestige sign-up offer is mighty tempting for those who’ve been considering a $120K card. While the minimum spend has increased from S$800 to S$2,000, the bonus miles on offer have also been hiked to 71,000. Even better, the offer is available to existing Citi customers too.

Finally, the StanChart Journey Card is offering 35,000 bonus miles with just S$3,000 spend, and you can pay the S$194.40 annual fee for an additional 10,000 miles (which I personally wouldn’t recommend, since that’s rather expensive). StanChart points can be converted to a wide range of airline and hotel loyalty programmes- if only the bank didn’t make it so painful!

Do note that you will only count as a new customer for the first card you apply for. Subsequently, you’re considered an existing customer. 

Conclusion

As with all credit card sign-up offers, it’s important to read through the T&Cs to confirm eligibility, qualifying spend definitions, and fulfilment timelines. Don’t panic if you don’t see the bonus immediately upon meeting the minimum spend; these usually take three months or more to process.

I also recommend saving a copy of the T&Cs for your own reference, because banks may overwrite the T&Cs when new campaigns are launched, or worse, retroactively modify them!
