The only constant in the world of points and miles is change. And just after overhauling and rebranding its loyalty program, Alaska Airlines is making more updates to its roster of partner airlines. It’ll drop one partnership entirely and scale back another.
Here’s what you need to know about how this affects redeeming Atmos Rewards points, earning them on eligible flights, and when the updates take effect.

Alaska Airlines Ending One Loyalty Partnership, Reducing Another
Part of the allure of the Atmos Rewards program (formerly Mileage Plan) is its roster of partner airlines. On most of these carriers, you can both earn and redeem points — often for fantastic value. But unfortunately, two of those partnerships with Singapore Airlines and LATAM are changing.
The details and timeline differ for each carrier, so we’ll cover what’s happening one by one.
Singapore Airlines
Let’s start with the not-as-bad news. Alaska Airlines’ partnership with Singapore Airlines is being scaled back.
Most importantly, starting October 1, 2025, you’ll no longer be able to redeem Atmos Rewards for award flights operated by Singapore Airlines. If you booked an award flight before these changes were announced for travel after October 1, the airline will still honor it.
The earning side of the partnership is changing, too. If you booked a ticket on Singapore Airlines and credited it to Atmos Rewards before August 31, 2025 (for any travel dates already ticketed), or if you book on or after September 1, 2025 for travel through December 31, 2025, you’ll still earn points at the current rates.

However, if you book a paid ticket on or after September 1, 2025 for travel on or after January 1, 2026 and credit it to Alaska, you won’t earn any points unless you buy the ticket on AlaskaAir.com and then submit a post-flight points credit request.
Booking through AlaskaAir.com can sometimes be more expensive than other channels or even via Singapore Airlines itself, so weigh any points you might earn against the fare difference.
Here's the link to submit this form.

LATAM
Now for the bad news. Alaska Airlines is ending its relationship with LATAM entirely, and the timeline is similar to what’s happening with Singapore Airlines.
Starting October 1, 2025, you’ll no longer be able to redeem points for awards operated by LATAM. That means now’s the time to grab one of those cheap business class awards to South America while they’re still available.
On the earning side, you’ll still get points at the current rates if you booked a ticket before August 31, 2025, for any date already ticketed. You’ll also earn points for travel booked between September 1 and September 30, 2025, as long as the trip is completed by December 31, 2025.
But if you book a LATAM flight on or after October 1, 2025, and try to credit it to Alaska Airlines Atmos Rewards, you won’t earn anything. You'll want to consider another program to credit your flights to.

Bottom Line
Like many other aspects of its loyalty program, Alaska Airlines’ roster of partners is changing, too. For those who care most about earning and redeeming Atmos Rewards points on partner flights, be advised: earning rates on two airlines being pared back or scrapped entirely, and redemptions on both Singapore Airlines and LATAM will end on October 1, 2025. These changes aren't great, to put it bluntly.
So, now’s the time to book awards on these carriers through Alaska Airlines Atmos Rewards before the window closes.
