If you want to play the miles game, a very important concept to understand is how to value a mile.
The recent SQ devaluation, as well as some insights I’ve acquired from speaking to fellow miles collectors, has led to a need to revisit this topic. This article should be read in conjunction with “What you need to know before you buy miles“, because presumably the price you’d be willing to pay depends on what you value them at.
In this article we will be discussing the value of a Krisflyer mile.
It’s probably easier to start by thinking about the theoretical value of a mile.
The theoretical value of a mile is the implicit rate at which the airline is willing to substitute miles for cash
Note that I say “implicit” because SQ may price a seat at S$2,000, but it doesn’t mean the cost to them is S$2,000. That’s just how much they hope to earn from it. The explicit value of a mile should form the floor, and that’s 1 cent per mile, the rate that SQ is willing to substitute miles for cash under its (poor value) Pay with Miles scheme.
Here’s an example of the theoretical value based on a round trip ticket to Paris on SQ.
The first thing you should note is that with the exception of economy to premium economy, as you move up the cabin classes the implied value of a mile increases. For the sake of simplicity I’ve only looked at one destination, but the figures above are pretty reflective of the average cent per mile value throughout the SQ network
- Economy- 1.5-3 cents per mile
- Premium Economy- 1.5-2.5 cents per mile
- Business- 3.5-4.5 cents per mile
- First- 6-7 cents per mile
This is because the incremental price increases more significantly than the incremental miles. Business Class cost 156% more money than premium economy but only 36% more miles. First Class costs 128% more money than Business Class but only 35% more miles.
Why the exception from economy to premium economy? Because SQ’s premium economy is horribly overpriced from a miles (and many would say money) point of view. Premium economy tickets require 75% the miles of business class. And given the huge gap in comfort, you’d be hard pressed to justify redeeming premium economy.
There is a price step up from economy to premium economy, but depending on what economy fare you book the step up can be very marginal, or even negative as we see in the CDG example above.
Based on this, we can formulate a general rule that
The value of a mile depends on what cabin you redeem for. Miles are worth the most when you redeem for first class and the least when you redeem for economy
Indeed, this general rule forms the mantra of many a miles collector- if you’re going to redeem your miles for economy class travel, you may be better off with a cashback card.
So that’s the theoretical value and although it remains a good starting point for our valuation of a mile, it cannot be the end. As this section shows you, valuing a mile is more art than science, and in some places even veers into the realm of the philosophical.
Here are some additional factors to take into account in valuing a mile.
What is the likelihood of finding saver space?
In the theoretical valuation section, I’ve used the saver award bucket when considering how many miles were required. But anyone who has spent 5 minutes trying to book an award ticket with SQ knows about the horrors of the waitlist. On popular routes like SIN-LHR or SIN-JFK, finding saver award space in premium cabins can be very tricky, if not impossible (I challenge anyone to find 2 instantly confirmable business or first saver seats on SQ25/26).
So we need to somehow factor in the probability of finding saver space. This isn’t a calculation I’m equipped to do because it depends on so many different factors like route, time of booking, number of seats etc.
I do know, however, that if you were to redeem standard awards instead of saver, your valuation would look like this (premium economy only has saver awards)
- Economy- 1-2 cents per mile
- Business-2-3 cents per mile
- First- 3-4 cents per mile
That’s about half the value of saver awards. Therefore your value of a mile is likely to be lower than what we calculated previously. I personally have never paid standard award prices (I find it too painful especially when I know what the price “should” be) but in an emergency situation I can see some people biting the bullet to do so.
Would I really have paid $10,000 for first class?
When I first started playing the miles game I’d tell people very proudly “I just got a $10,000 first class ticket for only $400 in taxes and some miles” and allow them to bask in my warm, enlightened glow (mind you, this is still how a lot of travel bloggers pitch stories to journalists because “YOU WON’T BELIEVE HOW THIS MAN GOT $20,000 OF AIR TICKETS FOR FREE” is a heck of a lot more attention-grabbing than “Man meticulously plans vacation through intelligent use of frequent flyer programs”)
I’d then lecture them about thinking twice for paying 2 cents per mile because “you can redeem them for first class and get 6-7 cents of value. It’s pure arbitrage!”
Ah, callow youth.
When Ubereats is (very often) late and gives me a $5 credit, I can safely say that I’ve saved $5 because I wouldn’t think twice on shelling out $5 of my own money on Ubereats in the future. But the only way I can take the first class ticket at face value is if I were genuinely willing to shell out that money in the first place. So I wasn’t wrong from a theoretical point of view, but implicit in what I’m saying is that I’d have been willing to pay $10,000 for a first class ticket.
And that’s the philosophy that some people take towards buying and redeeming miles. They tell themselves- I will not pay more than $2,000 for a return ticket to San Francisco, regardless of class. And then they’ll see if they’re able to buy/generate miles at a cost less than or equal to that. FYI, you’d need to buy miles at 1.1 cents each if you wanted to fly to SFO in Business Class and not pay more than $2,000.
This implies that you should think about all your alternatives when redeeming miles. If I don’t get my award seat, would I still fly with SQ?
Suppose I was going to Sydney. I could get there direct with BA, Qantas and even Scoot. So should I value my miles based on the retail price of a First Class ticket, or based on the retail price of the alternatives I’d be willing to accept? Just how much do I intrinsically value that flight to Sydney? You can see how this can quickly become a philosophical discussion more than anything.
Put it another way- if you’re the sort who would normally never pay for Tiffany jewelry, and Tiffany has a 10% sale and you buy a $10,000 ring for $9,000, you’d be stretching to say you really saved $1,000.
What is the opportunity cost of building miles?
A big part of building your miles as quickly as possible involves using the right card in the right situation. But that sometimes means forgoing discounts you could otherwise have received by using a different card.
Case in point- Citibank has a host of gourmet dining deals for its cardholders.
However, Citibank does not have a specialized dining card. The question I then face when I dine out is- do I value a 10% discount more than earning 4 mpd with my UOB PP Amex?
Of course if the discount is large it’s a no-brainer, but there are other situations where the opportunity cost is more subtle. Consider the Standard Charted Bonus$aver account, which awards you 1.88% bonus interest if you spend upwards of $2,000 a month on SCB credit cards.
SCB also doesn’t have a miles earning dining card. But it’s very hard for me to, on the fly, calculate the opportunity cost of not earning that 1.88% interest because of an individual transaction that may or may not cause me to fall short of the $2,000 mark. If you wanted to be completely accurate, you’d need to take this into account as well.
What about the miles I would have earned buying a revenue ticket?
Award tickets do not earn miles. Revenue tickets do. Therefore it’s necessary to factor the value of foregone miles into our calculations.
Business Class tickets usually earn 125% of the miles flown, so a return flight from SIN-SFO would earn 1.25*8,440= 10,550 miles, before you take into account the 25% elite tier bonus that Krisflyer Elite Silver and above gets. If you take a fairly conservative valuation of 2 cents per mile, that’s about $210 of value which you should offset from the revenue price of the ticket as a form of rebate.
How much do I value flexibility?
Award tickets have a great deal of flexibility. You can change the date for free, you can change your route/cabin class or award type for US$20 or cancel an award for US$15-30, depending on your status (and I know from experience that if you ask them nicely for a one-time exception they’re not above bending the rule)
This is more of an issue in economy, where tickets can range from fully flexible to highly restricted (although it should also be noted that the cancellation fee for a revenue business class ticket is US$150-300 versus US$15 for an award ticket) . So it’s not fair to compare the cheapest bucket of economy to an economy award ticket. An SQ super deals ticket to San Francisco may cost $1,408, but good luck if you need to make any changes to it.
Valuing a mile
And now we come down to the final question- how much should I value a mile?
My (very cop out) answer is that it depends on you.
- I personally value miles at 2 cents each.
- Ben over at OMMAT and TPG value miles at 1.5 US cents (or 2.05 SG cents) each.
- PointsHacks values them at 2..1 Australian (2.28 SG cents) each.
How you value miles is inherently linked to the kind of traveller you are. People who believe in saving money above everything else will value them lower, because miles are “free” (assuming you don’t pay explicitly for them). That’s why they’re willing to trade them for economy class tickets. People who believe in accessing experiences they couldn’t otherwise have afforded will value them slightly higher, because they’ll invariably redeem them for business or first. And people who buy first and business class as a matter of practice anyway will value them the highest, because to them it’s simply a replacement mode of payment.
So that’s my take on the valuation of a mile!
