Asiana Miles to Korean Air SKYPASS – Conversion Rates, Uses and Deadlines (2026)

After the merger on 17 December 2026, your Asiana miles can be kept separately as “former Asiana miles” for 10 years, or converted to Korean Air SKYPASS miles whenever you like. The conversion rate is 1:1 for flown miles and 1:0.82 for partner miles such as credit card points. (As of 19 October 2026)

I first wrote this when the final merger plan came out on 15 September, and have since added the later announcements and deadlines.

The final merger plan in short

The final plan for merging Asiana and Korean Air miles was announced on 15 September. Asiana was a full-service carrier for a long time, so plenty of people have Asiana miles of their own or family miles to use up.

Existing Asiana miles are kept separately as “former Asiana miles” for 10 years, and you can convert them to SKYPASS whenever you want. After 10 years they are converted automatically.
Former Asiana miles can be used 1:1 for Korean Air award tickets, whether you earned them flying or through partners. For Korean Air first class, premium class (not prestige) and SkyTeam awards, you have to convert first.
The conversion rate is 1:1 for miles earned flying Asiana or Star Alliance, and 1:0.82 for partner miles such as credit cards.
Asiana elite tiers are matched automatically to Korean Air tiers and keep their current validity. Diamond and term-based Diamond Plus are matched to a new Korean Air tier, Morning Calm Select.
Asiana mileage credit cards are no longer issued, but existing cards work until they expire. Card issuers will announce how cards earn miles after the merger.
Total yearly award redemptions (award seat supply) will rise step by step from 2025 levels, to at least 21% higher from 2030.

Being able to use Asiana miles 1:1 regardless of how you earned them sounds fair, but that only applies to Korean Air award tickets. Korean Air and former Asiana members will now be competing for the same limited award seats, so popular routes may get even harder to book.

Using former Asiana miles as they are

Former Asiana miles kept separately (source: Korean Air)

From 17 December all new miles go to SKYPASS. Asiana miles earned before then are managed separately as former Asiana miles for 10 years, with their original expiry dates.

You can use them for:

Economy and prestige award tickets on every route Korean Air flies
Upgrades from economy to prestige
Cash & Miles (from 100 miles, up to 40% of the fare)

You cannot use them for:

Korean Air first class or premium class
SkyTeam or partner airline award tickets
Combining them with SKYPASS miles on a single award ticket

Miles closest to expiry are deducted first, and you can’t choose between flown and partner miles. Family pooling and transfers follow your family registered with Korean Air. But if you convert your own miles to SKYPASS, your family can no longer use your Asiana miles.

Awards are priced on the Asiana chart (one way, off-peak / peak):

Region	Economy
Domestic (Korea)	5,000 / 7,500 miles
Northeast Asia	15,000 / 22,500 miles
Southeast Asia	20,000 / 30,000 miles
Americas, Europe, Oceania	35,000 / 52,500 miles

Prestige to the Americas or Europe is 62,500 / 93,750 miles, and an economy-to-prestige upgrade on those routes is 40,000 / 60,000 miles.

Converting to SKYPASS

Conversion rates (source: Korean Air)

Rate: miles flown on Asiana or Star Alliance 1:1, partner miles such as cards 1:0.82 (rounded up). For example, 10,000 partner miles become 8,200 miles.
You can only convert all of them at once, and you can’t undo it.
Apply on the Korean Air website from 17 December; it is processed within 5 business days.
Miles earned before 30 September 2008 have no expiry date, and they stay that way after conversion.
The Asiana website shows how many of your miles are flown and how many are partner miles.
When you convert, your flight activity on both airlines is combined and your tier is reassessed (it can only go up).

There is no official advice on whether converting is better. Korean press coverage suggests converting if most of your miles are flown, to get the tier reassessment, and keeping them as they are if most came from credit cards, since those lose 18% in conversion, and using them for economy or prestige awards.

Asiana elite tier matching

Asiana tier	Korean Air tier
Platinum	Million Miler
Diamond Plus (lifetime)	Morning Calm Premium
Diamond Plus (term-based), Diamond	Morning Calm Select (new)
Gold	Morning Calm

Your current tier validity is kept, and if you already have a Korean Air tier, you get the higher of the two.
The new Morning Calm Select tier gets SkyTeam Elite Plus benefits.
If you meet the requalification criteria for a term-based Asiana tier before the merger, it is extended by 24 months.

Will there be more award seats?

When Korea’s Fair Trade Commission approved the merger plan on 14 September, it attached conditions that apply for 10 years:

Award ticket travel must be at least the two airlines’ combined 2024 level, and at least the 2023 level for the Americas, Europe and Oceania.
Total yearly mileage redemption must be at least 106% of 2025 in 2027–2028, 112% in 2029 and 121% in 2030–2036.
Peak-season award seat supply is reported to an oversight committee.

Even if the total goes up, it remains to be seen whether people will notice the difference on busy routes in peak season.

Leaving Star Alliance and upcoming deadlines

Asiana leaves Star Alliance at 23:59 on 16 December. Star Alliance elite benefits also end with flights on 16 December.

Deadlines for Star Alliance partner award tickets depend on the airline:

Airline	Ticketing and travel deadline
Lufthansa, SWISS, Air New Zealand, Austrian, Brussels Airlines	31 October
LOT Polish Airlines	5 November
Air India, Ethiopian Airlines, EgyptAir	30 November
United, Singapore Airlines, ANA, EVA Air and others	16 December
Turkish Airlines, Avianca and two others	Ticketing by 16 December, travel by 16 December 2027

Other dates to note:

31 October, 23:00: last day to claim missing miles for Star Alliance flights up to 15 October
1 November, 22:00: last day to opt out of booking transfer (from 17 December Asiana flights get Korean Air flight numbers, and bookings are transferred between 2 November and 3 December)
2 November 09:00 – 16 December 18:00: retroactive credit for Star Alliance flights from 16 October onwards
2 November – 16 December: you can book Korean Air flights departing after 17 December with Asiana miles through Asiana’s channels
16 December: last day to refuse the transfer of your personal data. If you refuse, your Asiana Club membership is closed and your miles are lost, so be careful.

Asiana co-branded credit cards (Korea)

Asiana mileage credit cards are no longer issued, and existing cards work until they expire.
Hana Card and Lotte Card say their cards will earn Korean Air miles from 17 December, but haven’t announced earning rates yet.
Shinhan, Samsung, KB Kookmin and other issuers haven’t confirmed anything. Korean Air says each card issuer will announce its own terms.

Frequently asked questions

What is the Asiana to Korean Air mileage conversion rate?

Miles earned flying Asiana or Star Alliance convert 1:1, and partner miles such as credit card miles convert at 1:0.82. You can convert on the Korean Air website from 17 December.

Will my Asiana miles disappear if I don’t convert them?

No. They are kept separately as former Asiana miles for 10 years with their current expiry dates, then converted automatically. But if you refuse the personal data transfer by 16 December, your membership is closed and the miles are lost.

Can I fly Korean Air first class with Asiana miles?

Not as they are. Former Asiana miles only work for Korean Air economy, prestige and upgrades. For first class, premium class or SkyTeam awards, convert them to SKYPASS first.
