Reader’s Question: Can I Transfer Miles from One Airline to Another?

Editorial Disclosure: Opinions, reviews, analyses & recommendations are the author’s alone, and have not been reviewed, endorsed or approved by any of these entities.

I enjoy hearing from readers about their upcoming travel plans and fielding miles and points questions, including this question I was recently emailed.

It’s a pretty frequently asked question in my Facebook Group too so I decided to dedicate a post to it.

“Can I transfer miles from one airline to another?”

Unfortunately, airline miles cannot be transferred from one airline to another. 

For example, your Air Canada miles cannot be transferred to your United MileagePlus Frequent Flyer account.

However, all hope is not lost! 

Airline alliances and airline partnerships allow the miles from one airline to be used to book flights on another airline. But the miles aren’t transferred to do so.

The airlines must be in the same alliance or have a partnership in order for you to take advantage of this.

In the above example, Air Canada and United are both members of the Star Alliance so miles in one program can be used to book flights on the other airline.

The Star Alliance is just 1 of the 3 major airline alliances.

However, another airline, British Airways, is a member of the OneWorld Alliance and its Avios cannot be used to book flights on United, a Star Alliance member. They aren’t in the same alliance.

To make the most of your airline miles, knowing and understanding airline alliances is key.

There are 3 major alliances, Star Alliance, OneWorld, and SkyTeam.

Not only can you use your frequent flyer miles from one airline to book with a fellow alliance member, but you can also have your paid flights flown with one carrier credited to your account with another airline…as long as they’re within the same airline alliance.

For example, if you fly Air France/KLM, you can have the miles earned credited to your Delta SkyMiles account because Delta and Air France/KLM are both SkyTeam Alliance members.

“Where can I search and book partner award flights?”

The search engines on particular airlines’ websites often show their own flights, along with flights operated by partners.

For example, on United’s website, it’s possible to see flights listed that are actually flown by partners like Swiss or Thai Airways.

American Airlines shows award space for alliance members like British Airways, Iberia, and Qatar.

When booking my flights to Thailand, I searched on and redeemed United miles to book my award ticket but flew Thai Airways for a couple of the flight segments.

For our trip to Prague and Budapest, we searched on and redeemed American Airlines miles, yet we flew on partner airlines Finnair and Air Berlin (which no longer exists).

Here’s the points and miles golden rule to remember.

The amount of miles needed to book an award flight is determined by whichever airline miles you’re paying with, not the alliance member or partner airline you happen to be flying on.

For the above European flights, the number of miles for our award tickets to Prague was determined by checking the American Airlines off-peak award chart because we were paying with American Airlines miles.

If you have Delta SkyMiles and search for an award flight to Europe, you’ll pay Delta prices.

Unfortunately, if you compare pricing on a Delta partner like Air France and they have the same flight priced cheaper, your Delta SkyMiles cannot be transferred to Air France in order to take advantage of better pricing.

Delta miles are always Delta miles.

Things get a bit trickier when you have to search on one airline’s website to book with another or when you want to take advantage of a non-alliance partnership.

British Airways and Aer Lingus are partners, although not members of the same alliance. Aer Lingus is also a non-alliance partner with United.

To take advantage of an off-peak sweet spot to Ireland for 26k Avios round trip in economy, you’d have to:

  1. Search for Aer Lingus flights on United’s website.
  2. Call British Airways to book the award flight.
  3. Fly on Aer Lingus to Ireland.

United’s pricing doesn’t matter because you’re paying with Avios and taking advantage of a sweet spot.

British Airways doesn’t fly to Dublin from the east coast of the U.S. but their partner Aer Lingus does. A win-win for folks wanting to visit Ireland!

You’re probably wondering how it’s possible to remember which airline is in which alliance and which airlines are partners with one another.

It’s certainly A LOT of information and I definitely don’t have it all memorized. You don’t need to know it by heart either.

All you need is to understand airline alliances and partnerships. Then, do your homework while travel planning and researching flights to help you use the alliances and partnerships to your advantage!

Learning little by little and doing practice award bookings make the whole redemption process that much easier. Not to mention which airlines belong to which alliance!

Chase Credit Card Array

This is why flexible, transferable points earned on travel rewards credit cards are so valuable!

Chase Ultimate Rewards, American Express Membership Rewards, Citi ThankYou Points, and the Marriott Bonvoy Program all have airline transfer partners that can be used to book flights on a wide range of airlines around the globe.

Remember, you pay the price of the airline whose currency you have. If you can transfer flexible points to an airline with cheaper pricing, you maximize the value of your points and miles.

For example, transfer American Express Membership Rewards to Aeroplan or Avianca to book Star Alliance award flights for cheaper than United might charge.

Or how about transferring Chase Ultimate Rewards to Singapore Airlines to go to Hawaii in business class on a United flight?

Whichever way you choose to use your transferable credit card points, be certain you see the award space you want before transferring them because they can’t be transferred back. 

And, only transfer the number of points you need to book the award flight. Flexible points are more valuable when they’re flexible and not stuck in an airline program.

Bottom Line

So, even though you can’t transfer miles from one airline to another, there are still many ways to get the most out of your points and miles with the help of airline alliances, airline partnerships, and flexible point currencies.!

How have you used Airline Alliances and partnerships to your advantage?

  1. This was really informative! I need to learn more about airline miles and earning points! It seems like such a great way to save money for frequent travelers! My boyfriend lives in Europe, while I’m in the U.S., so we do lots of flying!

    1. Jackie Sills-Dellegrazie

      Thanks! Since you’re in the U.S., Kaylene, you have access to a lot of travel rewards options. Look into credit cards like the Chase Sapphire Preferred and make use of dining programs and shopping portals to earn miles and points for everyday purchase!

    1. Jackie Sills-Dellegrazie

      Awesome, Vedante! Thai Airways is so luxurious and the Star Alliance has many partners to use your points on! Enjoy your free flights! 🙂

  2. Great information, thanks for sharing. I love taking advantage of being part of the One World Alliance – we’re here in Australia so rack up Qantas points mainly, and it’s really lovely that we can use our points for so many other affiliated airlines. Looks like the Sky Alliance has quite a few more members though so I’m thinking it might be worth seeing if I can sign up for a few different mile accoutns and expanding my reach.

    Thanks for the tips!

      It’s always good to diversify your miles and points earnings, Meg. This way you have options and are protected if one airline decides to devalue its loyalty program. I love Star Alliance, particularly because United Airlines allows a stopover on award tickets, which is extremely valuable. It gives a free one-way. 🙂

    1. Jackie Sills-Dellegrazie

      Great, Holly! I would look at bank credit cards that offer transferable points to a variety of airline and hotel partners, like the Chase Sapphire or even the Starwood American Express. 🙂

  3. This is a great resource and perfect timing, as I soon will be booking flights for my family and me to Europe this summer. I’m not necessarily looking to book using miles but it will be good to know with which alliance I will be earning miles when we book. I need to get the kids signed up for miles, too, so they can earn their own!

    1. Jackie Sills-Dellegrazie

      Excellent, Francesca! So smart to get the kiddos earning miles too! Every little bit helps! Thanks for reading!

  4. HI Jackie, can you help with a question I have please? I have a SkyTeam membership with China Airlines and I also have a frequent flyer membership with China Eastern. I am at Gold membership with China Eastern Airlines. Can I apply my China Eastern miles towards a free ticket or ticket upgrade with China Airlines.?
    Thanks for your guidance

    1. Jackie Sills-Dellegrazie

      Thanks for reading, Kevin. Yes, both airlines are SkyTeam and your China Eastern miles can be used to book an award with China Airlines. You will follow the redemption rules and award charts of China Eastern since that’s who’s miles you’re using. Hope that helps! 🙂

    Hi Jackie. Can I transfer my point from Capital one (VENTURE)card to American airlines (AAdvantage)card?

    1. Jackie Sills-Dellegrazie

      Thanks for reading, Romulo. Unfortunately, Capital One points don’t transfer to American Airline and can’t be combined with points from another card.

  6. Hello Jackie, great website. I was wondering if it is possible and how to book Singapore Airlines with my United Airlines Miles. They are both Star Alliance members but the only option that comes up for a RT flight to Singapore (on UA website) is ANA airlines.

    1. Jackie Sills-Dellegrazie

      Thanks for reading, Leigh. I would play around with the dates. You should be able to search on United’s website for flights operated by Singapore. Perhaps there’s no availability for your dates or route. Good luck!

  7. Hi Leigh,

    Can I transfer United Airlines miles to my Aer Lingus account AerClub Avios account? Knowing this would be a great help.



    1. Jackie Sills-Dellegrazie

      Thanks for reading, Josh. No, unfortunately, you can’t transfer United Airlines miles to Aer Lingus. If you’re trying to book a trip to Ireland with Avios, check on United for availability operated by Aer Lingus. Then, call British Airways to book with your Avios. Good luck!
