Star Alliance Explained for Singapore Travellers
What an airline alliance is, why it matters for KrisFlyer and Singapore Airlines flyers, and how you redeem miles across Star Alliance partner airlines.
By The Miles vs Cashback Editors · Published 16 Jun 2026 · 5 min read
You book a Singapore Airlines flight, add your KrisFlyer number, and earn miles. Simple enough. Then one day you go to redeem those miles and notice you can fly to a city Singapore Airlines doesn't even serve, on an airline you've never flown. That quiet bit of magic is an airline alliance at work — and for KrisFlyer members, the relevant one is Star Alliance.
Here's what an alliance actually is, why it matters for your miles, and how redeeming across partners really works.
What an airline alliance is
An airline alliance is a group of airlines that agree to cooperate rather than treat each other purely as rivals. They keep their own brands, fleets and loyalty programmes, but they coordinate behind the scenes so that, to you, the experience feels joined-up.
In practice, membership of an alliance tends to mean three things:
- Shared networks. Members feed passengers onto each other's flights, so a single ticket can string together more than one airline.
- Reciprocal status. Elite-tier perks — priority check-in, lounge access, extra baggage — are recognised across member airlines, not just the one you're loyal to.
- Cross-airline redemptions. You can spend the miles from one programme on flights operated by another member.
There are three big global alliances. Star Alliance is the one Singapore Airlines belongs to. The other two are oneworld (home to Cathay Pacific, among others) and SkyTeam. Which alliance an airline sits in shapes where its frequent-flyer miles can actually take you.
Why Star Alliance matters to KrisFlyer flyers
Singapore Airlines has been a Star Alliance member since 2000, and that membership quietly does a lot of the heavy lifting in the local miles game.
If you collect KrisFlyer miles — and in Singapore, most miles credit cards ultimately feed into KrisFlyer — your redemption options are not limited to where Singapore Airlines and Scoot fly. Through the alliance, the same miles can be put towards seats on a long list of partner carriers covering routes and regions the home airline doesn't serve directly.
That matters for two reasons:
- Reach. A KrisFlyer balance suddenly opens up far more destinations than Singapore Airlines' own route map.
- Availability. When Singapore Airlines award seats are full on the date you want, a partner airline may have space — giving you a second, third and fourth shot at a redemption.

How redeeming across partners works
This is where a lot of people trip up, so it's worth being precise.
When you redeem KrisFlyer miles, the airline that operates the flight changes the rules. Singapore Airlines uses one award chart for its own flights, and a separate chart for flights operated by Star Alliance partners. The two are not the same, so the number of miles a given route costs can differ depending on who's flying you.
The practical upshot:
- A Singapore Airlines flight is priced off the Singapore Airlines award chart.
- A partner-operated flight is priced off the Star Alliance partner award chart.
- A trip that mixes both can be priced using a combination, which is why those itineraries are sometimes fussier to book.
To search for partner awards, you generally redeem on the Singapore Airlines website, switch the search to show Star Alliance flights rather than only Singapore Airlines, and book the seats you find. More complex itineraries — multiple connections, mixed airlines, stopovers — sometimes can't be completed online and need a call to KrisFlyer membership services.
The miles figures on either chart move over time, so treat any number you read anywhere as something to confirm against the current chart for your exact route before you commit. This is the heart of how miles redemption works.
Earning miles when you fly a partner
The alliance street runs both ways. When you fly a Star Alliance partner — not just Singapore Airlines — you can usually credit those miles back to your KrisFlyer account, as long as you add your KrisFlyer number to the booking before you fly.
A few things to keep in mind:
- The earn rate varies. How many miles you collect depends on the operating airline, the fare you bought and the distance flown. A cheap economy fare earns very differently from a flexible business fare.
- Add your number early. Put your KrisFlyer number on the booking at the time you book, or at check-in at the latest — chasing missing miles afterwards is a hassle.
- It's not a flat rate. Don't assume a partner flight earns the same as a Singapore Airlines one. Check the earning details for that specific ticket.
For most people in Singapore, though, flying is the smaller half of the equation. The bulk of miles still come from everyday card spend converted into KrisFlyer miles — see transferable bank points explained.
The catches worth knowing
An alliance is powerful, but it isn't a free-for-all. A few realistic limits:
- Award availability is the real constraint. Just because a partner flies a route doesn't mean award seats are open on your dates. Popular routes and premium cabins go fast, so flexibility helps enormously.
- Charts and partners change. Airlines join and leave alliances, and award charts get revised. What's true today may shift, which is exactly why we avoid quoting fixed mileage figures here.
- Taxes and surcharges still apply. Even on an award ticket, you pay taxes and any carrier-imposed charges in cash. These vary by airline and route, and can be meaningfully higher on some partners than others.
- Booking can be clunkier. Partner redemptions, especially complex ones, are often harder to pull off than a straightforward Singapore Airlines booking.
None of this should put you off. It just means the value of an alliance shows up when you redeem deliberately, not when you assume every seat is yours for the taking.
The takeaway
An airline alliance is simply a club of airlines that cooperate — sharing networks, honouring each other's elite status, and letting members redeem miles across the group. For Singapore flyers, the one that counts is Star Alliance, because Singapore Airlines is a long-standing member and KrisFlyer is where most local miles end up.
The payoff is reach: your KrisFlyer miles can fly you on partner airlines to places Singapore Airlines doesn't go, and partner award space gives you more chances to redeem. Just remember that partner flights use a different award chart, availability is the real limit, and taxes and surcharges are still paid in cash. Confirm the current figures for your route before you book, and the alliance becomes one of the most useful — and underused — parts of your KrisFlyer balance.
Frequently asked questions
- What is Star Alliance?
- Star Alliance is a grouping of major airlines that agree to cooperate — sharing networks, recognising each other's frequent-flyer status, and letting members redeem miles on one another. Singapore Airlines has been a member since 2000.
- Can I use KrisFlyer miles on Star Alliance airlines?
- Yes. Beyond Singapore Airlines and Scoot, your KrisFlyer miles can be redeemed for seats on Star Alliance partner airlines. This is one of the main reasons the alliance matters for Singapore flyers — it greatly widens where your miles can take you.
- Does it cost the same to redeem on a partner airline as on Singapore Airlines?
- Not necessarily. Singapore Airlines uses one award chart for its own flights and a separate one for Star Alliance partner flights, so the miles required can differ. Always check the figure shown for your specific route before you book.
- Do I earn KrisFlyer miles when I fly a Star Alliance partner?
- Usually yes, if you add your KrisFlyer number to the booking. The exact miles you earn depend on the airline, fare type and route, so confirm the earning details for your specific ticket rather than assuming a flat rate.
- Which alliance is Singapore Airlines in?
- Singapore Airlines belongs to Star Alliance, one of the three big global airline alliances. Cathay Pacific, by contrast, is in the oneworld alliance — which is part of why KrisFlyer and Asia Miles behave differently.
