How do I search for Star Alliance and One World award space?

Give yourself more award options. Learn how to look for Oneworld and Star Alliance partner award space.

Everyone reading this should know how to search for Singapore Airlines/Silk Air award space. But even among those who know they can redeem their Krisflyer miles for Star Alliance partner flights (and believe me, there’s a shocking number who don’t), few know how to go about searching for availability apart from giving random dates and routes to the CSO over the phone and hoping for the best.

SQ’s website has historically never allowed Krisflyer members to search for partner award space online. I’m not sure whether this is just sheer IT incompetence or a more deliberate move to limit partner redemptions (and therefore reimbursement payments to partner airlines), but whatever the case it leads to a lot of inefficiency when you want to redeem your miles.

Cathay is a bit better in this respect in that you can look for OneWorld award space through its online booking engine, but it’s notoriously buggy and does not display all OneWorld carriers. You’ll have to call in if you want to book MAS/AA space for example.

Given the vagaries of communication over the phone, it helps to call up prepared, knowing what is and isn’t available. Feeding flights and segments to the CSO can save you much hair pulling and it’s so much easier to put together a plan and then call rather than having to make decisions on the phone.

Here’s how I search for award space for Star Alliance and One World. Sorry, no SkyTeam guide.

Star Alliance

United Airlines

Don’t roll your eyes, but one of the worst airlines in the world has one of the easiest to use search engines for Star Alliance award space.

The best thing is that you don’t even need to create a MileagePlus account to use the search engine. Here’s the search box that appears on’s homepage. Just enter your destinations and dates, click “Search for award travel” and search.

Here’s the second thing I like about this engine. Unlike SQ’s annoying website that will only display one day at a time, shows you an award calendar with dates when saver award economy and saver award premium seats (i.e first and business class) is available. This makes searching for alternate dates easy.

You should be looking for “Saver” award space. This is the space that is available to Star Alliance partner carriers. “Standard” awards cost more, and are only available to members of United’s MileagePlus program. Think about it like Cathay’s Standard/Tier 1/Tier 2 awards system, which I explained here.

Don’t get confused by the prices displayed on the prices shown here are what Mileageplus members will be paying to redeem these saver awards. For example, a one way SIN-SFO award in Business Class costs a United Mileageplus member 80,000 miles + S$158.80 in taxes.

The same award would cost a Krisflyer member 97,500 miles + taxes (taxes is always a tricky one to guess because some airlines will pass on fuel surcharges and others don’t. You can confirm this when you talk to the CSO).  Always refer to the Krisflyer partner award chart to know how many miles an award costs.

One limitation (and it’s rather significant): does not display Singapore Airlines award space. Yes, the two airlines had a falling out a few years ago and like a mature adult, United decided to block all SQ award space from its website.

[Update 5 Oct 2017: United now displays SQ award space again]

Why does this matter, you think. Doesn’t SQ block its award space from most Star Alliance partners anyway? Yes and no. SQ blocks long haul F and J partner award space on their A350, A380 and 77W aircraft (basically, the good stuff)*. However, SQ’s regional business class on its A330s and 772s is available for partners to book.

*For the record, Miles and More (Lufthansa) members can book SQ premium cabin awards. But that’s not so relevant to us in Singapore because we can easily book such seats with Krisflyer miles anyway

So imagine I wanted to go from SIN-SFO. Two potential options are:

  • SIN-TPE-SFO (SIN-TPE on SQ and TPE-SFO on EVA) or
  • SIN-ICN-SFO (SIN-ICN on SQ and ICN-SFO on Asiana).

SIN-TPE and SIN-ICN are operated by SQ’s A330s that have the regional business class seat and hence are open for Star Alliance partner redemptions. But because’s website will not show SQ award space, neither option will appear! Therefore, even though it would be possible to get a Krisflyer agent to book such an award, you won’t know it exists by looking at

Which brings me to the other option for Star Alliance award searching:

Air Canda (Aeroplan)

Image result for aeroplan

You do need to create an Aeroplan account to search Star Alliance award space via, but it’s a five minute exercise. Once your account is created, feed your dates and routes into the engine

And get the results:

You’ll note on the top right hand corner the availability calendar

Click on this and you can see award space for other dates as well. Unlike United, it only shows you one week of award availability versus one month, but it’s still better than SQ…

More importantly, Aeroplan is able to see SQ award space and use that to knit together otherwise unavailable itineraries, as you can see in this SIN-ICN-SFO example below that uses SQ and Asiana.

SIN-ICN-SFO via SQ and OZ. Hey, I didn’t say the connections would be the best…

Once you’ve identified the dates you want, take down the flight numbers and timings. Then call up Krisflyer membership services and feed them the dates, flight number and flight timing. 99% of the time, they’ll be able to see the same things you see on the Aeroplan website. Trust me, you’ll be making their lives a lot easier. They’ll inform you the taxes applicable and issue the ticket over the phone. Congrats, you just booked an SQ partner award!

I know other people prefer using ANA’s search engine to look for Star Alliance award space, and it’s also possible (though less reliable) to use Lifemiles too. I’m not going to cover those here because I think Aeroplan should suffice for most regular users, but you can have a read on the ANA engine here.


So that covers Star Alliance redemptions, but you’re letting yourself down if you stop there. In Singapore you can also easily earn Asiamiles, and those Asiamiles can be used to redeem OneWorld award flights.

British Airways

Image result for british airways avios

You need to create an Avios account to search OneWorld space via Again, it’s a fast and painless process.

Once you plug in your dates and routes, you should be able to see results on different Oneworld carriers- see the example of flying QR to HEL and AY back.


I’m less of a fan of BA’s way of showing award availability over a range of dates- they only show 7 days and you need to click on an individual date to see what’s available.

On the plus side, you’ll see all relevant OW carriers here- including Malaysia Airlines. That should open up quite a few more routing possibilities for someone departing from SIN (in that it makes a lot more sense to fly SIN-KUL-SYD with MAS than SIN-HKG-SYD with CX)


Image result for qantas frequent flyer

Once you’ve created a Qantas account, you’ll be able to search for award space. Be sure to click the “Use points- Classic Flight Rewards only” button or you may not be able to enter certain cities.

Qantas has a much better availability calendar than BA. You can see, for a whole month, which days have economy/premium economy/business/first class partner awards with just a single click!

Here I’m looking for award space on Singapore to Rome. One important thing to note is that Qantas also partners with EK, which may result in some false positives for Oneworld award space (that is, Qantas shows availability but you won’t be able to use your Asia Miles to book EK space)

One limitation of the Qantas engine, as TPG points out, is that you’re not able to search for all Oneworld routes.

You can easily tell if the Qantas engine will work for your itinerary. If you input the airport codes of your desired itinerary, have the Classic Flight Reward option selected and you still can’t see your destination city as an option, Qantas does not have the capability to show you award seats. You need to use to look for award seats on that itinerary.

The same rules for Krisflyer apply here- once you know what dates and flights you want, give Asiamiles membership services a call to lock in your itinerary.


I understand booking partner award flights may seem daunting for some people, but it’s worth spending a couple of hours playing around with each of the award engines above to familiarize yourself with how they work, and (more importantly) how they don’t work. Armed with this knowledge, you’ll have much smoother calls with the CSOs when the time comes to book.

To US east coast it’s the number of KF miles you’ve written. To the west coast it’s 88K


Depends on YQ being charged though. What I find annoying is given the popularity of KF and AsiaMiles, I cannot (based on 5min of searching) get a definitive answer on which airlines charge YQ or similar on KF and AsiaMiles redemptions. It gets a bit crazy trying to talk about KF v partner redemptions by only looking at points, when clearly the total cost needs to factor in the variable carrier surcharges in addition to the points (I assume everyone charges the same tax, that should not change). Maybe a new topic to look at? My own experience: for KF,… Read more »


got it … sorry, misread!


Did test to find availability flight to ADD, it seems United engine exclude Ethiopian Air while Aeroplan include it .


Hi Aaron… what’s wrong with using AsiaMiles website to check availability? I manage to see available routes for Qantas, BA, Qatar, etc for several random searches


Can’t seem to register a “free” Avios account via the online portal at unless you already have a pre-existing Avios membership number (see the URL’s display).

So doesn’t look like those without an Avios membership number can use the online acct to do a OneWorld search at…….or am i missing something? 🙂


What does CSO mean?

Hi, i have a Marco Polo account and have been accumulating Asiamiles. Do you mean that if i register for an Avios account, i can use it to search for flights and redeem One World carries using Asiamiles? Is my understanding correct?
