First off, let me state that if you read the title and went “well, duh”, then congratulations, this article isn’t for you!
But given how many times I hear this question, I thought I’d write a post to properly lay out the shortcomings of a one card strategy. If you’re a miles convert who’s tired of explaining this to family and friends, feel free to point them here.
Why one card just isn’t enough
Now I completely understand why some people prefer to use one card for everything and call it a day. After all, we want convenience. We don’t want to bulk up our wallets with multiple cards, juggle multiple payments each month, or keep track of multiple ibanking logins.
If you’re playing the miles game, however, using one card for everything is like being stuck in the slow lane. It means more spending to earn the same reward, fewer free flights, and leaving value on the table. Here’s why:
You miss out on sign up bonuses
If you’re just starting out in the miles game, sign up bonuses are like the cheat code for rapid miles accumulation. Spend a lump sum within a given period, and there’s a pot of miles waiting for you at the end of the rainbow.
By using a one card strategy, you’re missing out on many opportunities to capitalise on big ticket spending. A wedding here, a renovation there…all these are great ways of generating a large amount of miles from spending you’d need to do anyway.
You miss out on specialized spending bonuses
Even if you don’t qualify for sign up bonuses, you’re still missing out on specialized spending bonuses by using a one card strategy.
What is specialized spending? Simply put, it’s categories of spending which banks award bonus points for, such as dining, online shopping, contactless payments, travel or foreign currency transactions.
This is what we mean by using the “right card in the right situation“, because on average, you can earn about 4 mpd with specialized spending bonuses. Needless to say, someone doing this will accumulate miles a lot faster than someone using the same card everywhere and earning 1.2-1.5 mpd.
Comparing a one card strategy to a portfolio strategy
Let’s say you’re just starting off in the miles game, and want to use one card for everything. You’ve done your research and feel pretty good about picking one of the highest earning miles cards in the market- the BOC Elite Miles World Mastercard (clearly, you don’t mind drama). You like the fact that you’ll earn 1.5/3.0 mpd on local/overseas spending, significantly more than other cards like the DBS Altitude or UOB PRVI Miles.
Now assume you spent $30,000 over the course of a year, split into 25% on dining, 30% on online purchases, 10% on shopping, 15% overseas and 20% on miscellaneous spending. All in all, you’d have 51,750 miles by the end of the year. That’s a decent haul, enough for a round-trip Economy Class ticket to Tokyo.
But consider the alternative. Let’s say you looked to maximize your sign up bonuses, and applied for five different cards- the SCB X Card, Citi PremierMiles Visa, AMEX Rewards Card, OCBC 90N and DBS Altitude. The same $30,000 of spending would yield 154,100 miles in total, almost 3 times the miles. That’s enough for a round-trip Suites ticket to Tokyo, with 14,100 miles to spare.

Now, you could point out that someone who follows this strategy will have to pay a total of ~$800 in annual and conversion fees. That’s fair enough, but put it another way-if I stood at the check-in counter and offered Economy Class passengers to Tokyo 14,100 miles plus an upgrade to Suites on both legs for $800, I’d have no shortage of takers.
Even if you don’t qualify for sign up bonuses, you could still adopt the strategy below and earn more miles by using the right card in the right situation:
- Citi Rewards Visa for online purchases and offline shopping
- OCBC 90N for overseas spending
- UOB Lady’s Card for dining (only available for women, but let’s go with that for argument’s sake)
- UOB Preferred Platinum Visa for contactless spending
In a best case scenario, you’d have up to 120,000 miles, less than with sign up bonuses but still significantly more than with a one card strategy. To put that into perspective, it’s enough for a round-trip Suites ticket to Shanghai (where you can try the 2017 Suites on SQ833/830), quite the upgrade from an Economy Class jaunt to Japan/South Korea.
What this illustrates, I hope, is that the convenience of a one card strategy comes at a hefty cost.
Viable one card options
Now, if in spite of everything I’ve said you absolutely, positively must use one card for everything, then you’re going to want to look at general spending cards that at least incorporate a range of specialized spending bonuses.
|Card||General Spending||Specialized Spending||Remarks|
|KrisFlyer UOB Credit Card|
|1.2 mpd for local|
1.2 mpd for overseas
|3.0 mpd on SIA-group purchases|
3.0 mpd on dining, food delivery, online shopping and travel, and transport, with min $500 spend on SIA-group in a year
|3.0 mpd on SIA-group transactions credited immediately. Otherwise, 1.2 mpd awarded initially, bonus 1.8 mpd credited 2 months after membership year|
|1.2 mpd for local|
2.0 mpd for overseas
|3.0 mpd on online airfare and hotel bookings||Bonus capped at $5K per month|
|1.2 mpd for local|
2.3 mpd for overseas
|1.6 mpd for dining||Non-waivable annual fee of $488 applies|
|1.2 mpd for local|
4 mpd for overseas
|4 mpd for SIA, SilkAir, Scoot, Air Asia, Jetstar, DFS & Shilla @ Changi, Netflix, Spotify|
8 mpd for Airbnb, Millennium Hotels, Agoda, Expedia, Mr & Mrs Smith
|Bonus rates apply until 29 Feb 2020|
It’s important to highlight that the specialized spending bonuses on general spending cards will still pale in comparison to outright specialized spending cards. This is not optimizing; it is making the best of a sub-optimal situation.
Can I use one card for everything? Yes, but you won’t get anywhere fast. It’s kind of like buying a washer dryer. It’s convenient, but the drying will never be as good as a stand-alone dryer (something I’ve discovered to my chagrin over the past few months).

Look, it’s not that miles chasers love complicating their lives. We don’t. If there were really a card that gave you awesome earning rates on everything, we’d be all over it so fast.
Unfortunately, that’s just not how this works, and we’ve accepted the implicit deal that the cost of a free flight is some short term headache in applying for, tracking and maintaining multiple cards.
But trust me, when you’re sitting in Business Class with a glass of champagne, that’s the last thing you’ll think about.
