Korean Air Is Absorbing Asiana on December 17 — What Happens to Your Miles?

Korean Air Is Absorbing Asiana on December 17 — What Happens to Your Miles?

It's been dragging on for years, and this week it finally got real. On August 12, Korean Air's board and Asiana's shareholders both signed off on the merger, with completion locked in for December 17, 2026.

If you're sitting on Asiana Club miles — or you've been eyeing Asiana as a Star Alliance award option — there's a date you need to circle and a question nobody can answer yet. Let's separate those two things carefully, because a lot of coverage is blurring them.

What actually got approved

At Asiana's extraordinary shareholders' meeting, 81.86% of shares were represented and 99.3% voted in favor. That's not a close vote. That's a formality clearing its last hurdle. So the merger is happening. Asiana stops existing as a separate airline and becomes part of Korean Air on December 17.

The date that matters more: December 16

Asiana leaves Star Alliance on December 16, 2026 — one day before it folds into Korean Air.

Quick explainer if "alliance" is new to you: an airline alliance is a group of airlines that agree to honor each other's miles and status. There are three big ones — Star Alliance, Oneworld, and SkyTeam. Being in the same alliance is why you can use, say, United miles to book a flight on a completely different airline.

Asiana has been in Star Alliance. Korean Air is in SkyTeam. When Asiana switches teams, every Star Alliance program that could previously book Asiana flights — United MileagePlus, Air Canada Aeroplan, Turkish Miles&Smiles, ANA Mileage Club and the rest — loses that ability. So if booking Asiana with Star Alliance miles is part of your plan, December 16 is your wall. Not a soft deadline. A wall.

The part nobody can tell you yet

Now the honest bit, and I'd rather be honest than confident. We do not know how Asiana Club miles will convert into Korean Air SkyPass. No final ratio has been published. Korea's Fair Trade Commission previously rejected a proposed mileage conversion plan and sent it back for revisions, and as of now there's no confirmed replacement.

You will see people online stating a specific conversion rate with great confidence. Be skeptical. Until the airlines publish terms, anyone quoting a number is guessing. What I'd expect, based on how mergers usually go: conversion will happen, it probably won't be strictly 1:1 in your favor, and there will be a defined window with instructions. What I wouldn't do is make expensive decisions today based on a rumored ratio.

What this means for you

If you have Asiana Club miles: don't panic, and don't dump them into something bad just to "use them up." Merged programs generally do honor member balances — that's the norm, not a favor. But if you have a redemption you actually want and the seats exist, using miles before a merger is rarely the wrong call. Certainty has value.

If you were planning to book Asiana with Star Alliance miles: this is your genuine deadline. Flights need to be booked while Asiana is still a Star Alliance partner, and existing bookings for travel after the switch are exactly the kind of thing that gets messy. If it's on your list, move it up.

If you have Korean Air SkyPass miles: mostly good news, long-term. A bigger Korean Air means a bigger route network to spend miles on. SkyPass has historically been a somewhat awkward program to use from the US, and consolidation doesn't automatically fix that — but more routes is more options.

If none of this applies to you: file it away as a useful lesson. This is what alliance risk looks like in practice. Miles parked in a single airline program are exposed to decisions you don't control — mergers, alliance switches, devaluations. It's a solid argument for keeping most of your balance in flexible bank points and only transferring when you're ready to book.

Is this good or bad?

Our honest read: mildly bad for award travelers in the short run, genuinely uncertain long-term. Losing Asiana from Star Alliance removes a useful option — Asiana had a solid business class product and reasonable partner availability out of the US. Consolidation also means one fewer competitor on Korea routes, and less competition has never once made award seats easier to find.

The counterargument is real, though: two struggling carriers merging into one healthier one is better than one of them failing. A stronger Korean Air with a bigger network could end up more useful than a weaker Asiana was. We just won't know for a year or two. Either way, December 16 is the date. Everything else is speculation until the airlines publish terms.

Merger terms and mileage conversion policies have not been finalized. Confirm details directly with Korean Air and Asiana before making decisions about your miles.
