Japan Airlines (JAL) has just partnered with Citi, allowing 1:1 transfers and offering a limited-time 30% transfer bonus on top.

Citi ThankYou Adds JAL as a 1:1 transfer partner

JAL sure is getting around these days. After long hiding in the shadows of the transferrable points currencies (we’re not counting the not-available Barclays Arrival Plus), JAL started making moves. JAL Mileage Bank joined the programs offered by Bilt, Capital One, and Rove. But while there was a little lull since the last inclusion, it seems JAL wasn’t done.

Citi ThankYou now has the ability to transfer points over to JAL Mileage Bank at a 1:1 ratio if you have one of the following cards:

• Citi Strata Elite
• Citi Strata Premier
• Citi Prestige (no longer available)
• AT&T Access More (no longer available)

Other cards, like the regular Citi Strata, transfer at a weaker 1:0.7 ratio.

What makes Citi ThankYou so intriguing as an option is the ability to earn lots of bonus points if you have the right cards. Cards like the Citi Strata Elite, Citi Custom Cash (no longer directly available), and AT&T Access More (no longer available) allow you to load up on the points.

JAL has some nice sweet spots

The JAL Mileage Bank program has some sweet spots to know:

• Excellent business class pricing on JAL’s own flights
• Good-to-great pricing on JAL first class flights
• Great pricing on Emirates business class flights
• The program is the king of free stopovers

But before you start moving over all your points to JAL, keep in mind that there is a hard expiration policy. JAL miles will expire after three years with no way to extend them. Don’t transfer without a redemption firmly in mind.

Enjoy a limited-time transfer bonus

Now through Saturday, October 24, 2026, you can get a bonus 30% for transfers you make from Citi ThankYou to JAL Mileage Bank. This bonus improves the transfer rate from 1:1 to 1:1.3 on the four cards listed above. Other cards will improve from 1:0.7 to 1:0.91.

In some ways, this bonus from Citi ThankYou is taking the air out of the Capital One transfer bonus that overlaps. Capital One’s normal transfer rate is 2:1.5 and also offers a 30% bonus that gets it oh-so-close to a 1:1 ratio (2:1.95). That bonus lasts only until September 30, but really just gets it in line with the normal transfer bonus from other programs.

Thus, unless you’re flush with Capital One miles, don’t bother transferring points over to JAL.

Sure seems like the program is ripe for a devaluation

You don’t rapidly expand transfer partners like this and expect to have the same award levels indefinitely. A rapid influx of points increases the supply of points, but the problem is the number of flights doesn’t change. Thus, there are more people with points fighting over the same scarce seats. People complain to the airline about being unable to use awards–or rather, they “complain” by disengaging with the program–and the airline responds by upping the award rates. That thereby makes it harder to purchase a seat with points and availability naturally opens up again.

That’s the same cycle that all loyalty programs go through. How fast and frequent a program goes through this cycle depends on how fast new points are minted. In other words, now that JAL continues to pair with more transferrable currencies, move up your mental timeline for when a devaluation hits. I’m not going to place a wager on when exactly it will happen, but it sure seems inevitable.

It’s another reason to place caution on not going overboard with this transfer bonus. There’s no guarantee the value you expect to get will be there when you are ready to redeem.

With that in mind, are you excited about the Citi and JAL partnership?
