The ultimate goal of award travel is redeeming points and miles to pay for flights, saving the cash outlay required to purchase revenue fares. But if you travel regularly, for business or pleasure, a significant portion of the flights will be revenue tickets that earn miles in the airline’s respective frequent flyer program.
Unless you are loyal to one airline, collecting miles in a single program, you could wind up with small balances spread across several frequent flyer programs. Amassing just enough miles to get absolutely no value from any of them! The critical thing to know is that you don't need to credit miles to an airline's frequent flyer program just because you took a flight with them — you can credit your mileage earning to any of their partners!

The problem with having miles spread over multiple programs is it’s hard to accumulate sufficient miles for even economy award tickets, let alone the more aspirational redemptions of flying business or first class. While AwardWallet can help keep track of all your account balances, you can’t combine miles from different programs to pay for an award ticket.
The best way to avoid having miles spread across a multitude of frequent flyer programs is to credit the miles earned from different airlines to a small handful of frequent flyer programs, building a usable balance of miles in each account.
Why Credit Airline Miles to Partner Frequent Flyer Programs?
The Scenario
Let’s say you fly United on a regular basis. You are most likely signed up to the United MileagePlus® frequent flyer program, and your frequent flyer account is added to your booking when you sign into United’s website to complete your reservation, crediting your miles to United. But what happens when you're overseas and flying domestic or international routes that United doesn’t service? Or you catch a fare that’s too good to resist, but it’s on different Star Alliance carrier?
For example, if you catch a revenue flight on Air New Zealand traveling between New Zealand and Australia. Air New Zealand operates a frequent flyer program called Airpoints. You could open an account and credit your miles to Airpoints. But you would be left with a small, unusable balance stuck in a program you can’t transfer points out of, and those points will expire after four years whether there is account activity or not.
The Solution
In this case, crediting those miles to almost any Star Alliance partner will net you a better return than crediting your miles to Air New Zealand. You could credit to United MileagePlus, adding to the balance you already have. Or credit to Singapore Airlines’ KrisFlyer program, a program that counts all four flexible rewards currencies as transfer partners, allowing you to scavenge points from multiple rewards programs to redeem an award. If you collect Membership Rewards, you could credit to ANA Mileage Club, or if you collect Citi ThankYou Rewards, you could credit to Avianca LifeMiles, allowing you to top off your account with ThankYou Points to reach a redemption.
Airline partnerships and alliances let you credit miles from any airline within that partnership to one or more partners whose miles offer the best value. You can focus all your mileage earning capacity on a handful of programs that provide top value. The trick is to select frequent flyer programs that offer excellent redemption value, and, are transfer partners of one or more flexible points programs so you can top off your account using points that are easier to accumulate.
How Do You Credit Miles to a Partner Frequent Flyer Program?
You have several opportunities to credit miles to partner frequent flyer programs when purchasing a revenue ticket. If you’re booking directly through the airline, you can typically add your frequent flyer number during the booking process when you enter the passenger details portion of the reservation. Yes, if you book a ticket with Air New Zealand, when you're going through the check out process you'll be able to enter your United MileagePlus account number.
If for some reason, the system doesn’t accept your number, or there isn’t an option to add your frequent flyer number to the booking, you can call the ticketing airline after the ticket is confirmed and have the frequent flyer number added to the reservation manually.
There are also chances to add the number at the airport when you pass through check-in or at the gate, and if all else fails, you can try and claim the miles retrospectively after you’ve completed the flight.
When Does It Make Sense to Credit Miles to Partner Programs?
Perhaps the hardest part of the equation is working out where to credit your miles. How many miles you receive in the partner program depends on the fare bucket of the ticket you’ve purchased, typically shown in the ‘Flight Details’ section of your confirmation email as ‘Booking Class’ and a single letter, as shown in the picture below.
Our favorite resource when deciding where to credit miles is WhereToCredit.com. Just select your airline and booking class and hit ’Show Me‘ and it displays the portion of miles you’ll receive when crediting to different partner programs. The percentage of miles you receive differs between fare buckets, and some discount fares won’t receive any miles at all on partners, to get the most accurate result you’ll need to know the booking class of the fare.
Another factor to account for is whether the program you credit to partners with flexible rewards programs. Transferable points provide ultimate flexibility and allow you to top off accounts when aiming for a specific redemption. If the program you credit towards has more than one big transfer partner, it will be easier to reach your goal than if you’re required to earn the miles within that frequent flyer program’s ecosystem.
The other circumstance which warrants crediting miles to partner programs is if you’re chasing status. Crediting miles to your preferred frequent flyer program allows you to leverage flights on partner airlines to achieve elite status with your chosen airline. We’ve detailed fast tracks to elite status with Star Alliance using this method, where you can reach Star Alliance Gold by crediting flights to Egypt Air.
Final Thoughts
Crediting airline miles to the right frequent flyer partner has a significant impact on the number of usable miles you bank. Like most things in award travel, it’s best to have a plan and know in advance to which airlines you want to credit miles.
By targeting programs with flexible partners, you can transfer points from everyday spend combos like the Chase Sapphire Preferred® Card paired with the Chase Freedom Unlimited®, or The Platinum Card® from American Express paired with Amex EveryDay® Credit Card, to top off your accounts and land that big award travel redemption.

Wheretocredit is a great reference site to use.
Now this is a good website to know about! I’m always looking at the best place to credit miles. I even use another site about the shopping portals that I got from you guys. It’s awesome and an easy way for me to see the best place to get miles credited. Now I have another tool in my arsenal. Thank you! Plus, it looks like it stays up to date on changes with partners too, since I see the Alaska and American changes on there under the notes.
Thanks. I like that website.
Partner mileage earning is a great benefit. Makes earning easier.
Wheretocredit is a great site for quick reference before pulling the trigger on those super error fares!
I love that website. It’s so incredibly helpful at determining mileage credit. I always try to credit to my preferred program but hate it when a flight is listed as 0% accrual rate.
I actually just did this for the first time. Credited an AA flight to AS to save for my Australia trip!
Thanks for the post!
Don’t make the same mistake I did… transferred amex MR to ANA to get on a BC waitlist only to have ANA not give me the award tickets even though there are 20+ seats available.
The seats went out empty?
I guess you’re stuck with the miles now?
What I do is to save my boarding passes till I’m sure the miles are credited. But, like the article advises, I always try to enter my frequent flier # while booking. For example, I entered my Delta # while booking Alitalia flights, and that worked for me.
This is one of my favorite resources. On our big overseas trips, we usually book with miles for the long haul, but pay cash for the short flights during the trip as we explore a region. This site has been very helpful when flying on regional airlines in a region we may never visit again so we don’t feel like we “wasted” the miles.
Recently I’ve used Wheretocredit, to find the best option(s) for crediting revenue flights we’ve booked on some relatively obscure regional carriers, and some less obscure foreign carriers, with great success. It’s really a terrific resource.
Really helpful tips, particularly the Wheretocredit.com site. I’ll be referencing that in the future!
Some great tips, thanks!
If you are not loyal to one airline, it is often best to keep one account from each major alliance. Alaska Airlines also have a wide variety of partners.
I always use wheretocredit to check which program to use.
great info. just discovered this site, thanks
great advice
thanks for the info
Thanks for the info. This is getting really complicated to optimise
Very important to consolidate miles. The first place I check is wheretocredit
I’m just learning more about flexible programs and their obvious benefits… wow, a whole new world of point programs and things to consider. Life was so much simpler before, but my points are not nearly so useful and usable being locked into one program. I just wish i could remember all the details covered in these article blogs.
I knew about the where-to-credit-Page..but i don’t get how it works…Like, having a LH-Flight in N – it says 125% – but 125% of what?
125% of miles flown.
Thank goodness for airline alliances and partnerships!
thanks for the info
Thanks for the tip. I guess that I have just been letting earned miles just expire on these one off airlines that I have flown in the past. I will look into WhereToCredit.com going forward.
As have many of us. 🙁 Good to know of a way to plan ahead and avoid the one off complete losses.
Very useful article! I am likely going to book a flight in the next few days and I’m chasing status on American Airlines. The suggestion of wheretocredit.com will really help me out. Thanks!
If you are chasing status on one airline, that really helps make it easier to decide where to credit, as you send everything you can towards that airline.
Thanks for the useful information on where to credit miles. I never knew about this website.
Thanks for “WhereToCredit.com”. I’m going to bookmark that resource.
