I’m going to talk about a dilemma I rarely face–where to credit the miles earned by flying a paid ticket. I rarely face this dilemma because I rarely buy tickets; I almost always fly for free (plus tax) with miles.

If I’m flying a paid ticket, it’s probably a mistake fare–$238 roundtrip to Peru or $170 roundtrip to Central America–or just generally too cheap of a flight to make using miles a good deal–$36 oneway to Vegas is better than 4,500 Avios and $1,100 roundtrip to East Africa is better than 80,000 United miles.

Some people fly more paid fares, often because someone else is doing the paying. And on most paid fares, there is a decision to be made: where do I credit the miles earned from flying this itinerary?

Flying earns two types of miles, redeemable miles and status miles.

Redeemable miles are the fun kind that you use to book dream awards like a flying bed to Australia. You earn them by flying paid fares, signing up for credit cards, and a ton of other ways.

Status miles cannot be redeemed for anything. They are simply a counter that airlines use to determine whether you qualify for status. Different airlines call status miles different things. United calls them Premier Miles; others call them Elite Qualifying Miles or Medallion Qualifying Miles. Status miles are mainly earned by flying paid fares (although some credit cards offer some status miles.) Certain expensive fares earn bonuses; certain cheap fares only earn a fraction of the miles actually flown.

Every time you fly a member of one of the three alliances, you have the option to credit the miles earned to any of the alliance partners. And even when you fly an airline that isn’t part of an alliance, you sometimes have the option to credit your miles to one of several programs. How should you choose where to credit your miles?

The first step is knowing all your options. Each airline maintains a page on its website with all its airline partners listed on which you can earn miles. Generally the page can be found by clicking “earn miles” then “airline partners” or something similar inside the airline’s loyalty program section. United’s page looks like this:

Each airline logo is a link that takes you to the information on earning miles on that airline. Remember how I said certain fares earn a bonus and certain only earn a fraction of the miles flown? Clicking on an airline will give all those details. For instance, here is TACA’s page:







This chart shows how many United miles–both redeemable, labeled “base,” and status, labeled “premier qualifying”–you would earn from paid TACA fares in each possible fare class. Since I never buy paid business class, my eyes head straight to the bottom of the chart. As you can see, certain fare classes only earn 50% of the flown miles as redeemable miles and status miles. When you purchase a ticket, somewhere its fare class should be listed. If not, you can call the airline to ask.

The mistake fare I booked to Lima for later this year was fare class U, so for the 8,504 miles of flying, I could earn 4,252 redeemable miles and 4,252 status miles from United. Since TACA is now in the Star Alliance, I could also credit the miles to US Airways. How many miles would I get there?







I would earn the  same 4,252 redeemable and status miles from US Airways. In most cases, the miles earned  are the same on US Airways and United, but not always, so it’s always worth it to check.

Once you’ve checked the airline’s accrual charts, you should make a decision based on where you will get the most value from status miles and redeemable miles. You have to pick one airline on which to accrue both the status miles and the redeemable miles for your trip, so pick the airline that offers the best combination of value.

Redeemable Miles– If status is far from your mind because you mainly fly short, one-carryon-bag-no-checked-bag domestic flights and international premium cabins, like I do, then you should mainly focus on where you want to earn redeemable miles. If you have specific future redemptions in mind, choose to earn miles in the program you will use for the redemption. If you don’t have a specific future redemption in mind, choose the airline whose miles you value the most in general.

Status Miles- Status miles get more valuable the more you earn on one airline generally. 25,000 status miles earned on United is better than 12,500 on United and 12,500 on American, for instance, because the latter earns no status while the former earns United Premier Silver.

50,000 on one airline is also better than 25,000 on two airlines because one mid-tier status is generally reckoned to be much more valuable than two low-tier statuses.

Pick at the beginning of the year which airline’s status you would most like, and try to funnel your travel to that airline and its partners. And when flying its partners, credit the miles to the account of the airline whose status you want.

An example I gave a few weeks ago was my earning United Silver status this year. I saw that I was flying 25,000 miles on Star Alliance members on two itineraries this year, so I decided to credit all the miles to United because I value United status more highly than US Air status.

A lot of times people contact me to book an award for them and when they list their mileage balances, they have a random few thousand in a Singapore or Lufthansa account. That should basically never happen. Credit your miles to an account where you might earn status, or at least to an account where you will get enough miles eventually to redeem them for an award.


Carefully strategize where to accrue miles from paid flights. Consider where you want the redeemable miles, and where you want the status miles, then choose the program that gives you the best combination of value from those two types of miles earned from paid flights.

In general, you should try to credit all paid flying to one airline or, at most, one airline per alliance. If you do that, you’ll maximize status benefits, and you’ll ensure that your redeemable miles aren’t orphaned in worthless accounts.
