Star Alliance will open a new lounge at Seoul Incheon Airport in late 2026, taking over the former Asiana Business Lounge as Asiana exits the alliance.
There is something sad about Asiana going away. Was a cool local airline. Had quite a lot of fun flying their A380 to LAX couple years ago.
Don't worry, even though they said they might retire their a380s soon, they're probably sticking around for a few more years while Korean waits for the 777X. They might not even repaint the exteriors or reconfigure the interiors, so you can just pretend it's like flying Asiana still. (However, I'd prefer the Korean ones because Asiana's were far more dense; Asiana 495 vs. Korean 407.)
I recall SQ has its own SilverKris lounge in Terminal 1, which is probably better, anyway; but, it's small and its schedule is limited to SQ flight times (reminiscent of SQ at MNL T3 as well). For the United folks (EWR-ICN did just start), would you pick SQ, or this old Asiana/'new' Star Alliance lounge?
The food in those lounges can only get better. I have not been to West one, but i was in the East and Central one. And its atrocious to see an airline that is based in a region with such amazing food, lay an egg in what it offer at its lounges.
