In August 2026, I covered how Starlux Airlines’ COSMILE frequent flyer program finally got into the business of selling miles to consumers. Without any sort of a promotion, it wasn’t exactly some amazing deal, but it was still the best way to unlock first class travel on Starlux Airlines, so it’s something I took advantage of almost immediately .

Well, there’s now an exciting update, as Starlux has launched its first-ever promotion on buying miles, and you can buy these miles for 40% off! This is actually a way to fly Starlux first class at a pretty reasonable cost.

For a little bit of background, Taiwan-based Starlux Airlines launched its COSMILE frequent flyer program back when the airline commenced operations, in 2019. Unless you live in Taiwan or constantly fly with Starlux, you probably shouldn’t care much about the program — the only airline partner is Alaska Airlines, and if you want to redeem on Starlux, you’re generally best off redeeming Alaska Atmos Rewards points .

However, in August 2026, we started to see a new way to earn miles in the COSMILE program, as the airline has started selling miles directly to consumers . To access this, just log into your Starlux account, go to the “COSMILE” section, and then click on “Mileage Purchase.”

Without a promotion, the program is charging a flat four cents per mile, and members can purchase anywhere from 1,000 to 150,000 miles per transaction. 150,000 is also the annual limit on how many miles you can buy. Purchases are processed by points.com, as is common for the points purchase programs of many loyalty programs.

That brings us to the exciting update — between October 15 and November 9, 2026, Starlux is offering a 40% discount on the purchase of miles, and that applies no matter how many miles you purchase. With a 40% discount, you’d pay just 2.4 cents per mile, obviously a huge discount over the standard price.

Long story short, I think the real upside with buying Starlux miles is the ability to redeem for Starlux first class, and this is something I recently took advantage of, even when buying COSMILE miles without a discount.

Starlux Airlines has a quirky first class product — it’s available on all A350s, the pricing is very high, and there’s not even a curtain between first and business class. From the time the airline launched, I tried to find a way to get a deal on the experience.
