Curiously, although the runway is clearly unusable, there is no NOTAM or comment on the ATIS- lots of folk requesting the usual landing runway and wondering why not.
Looks to me like the runway closure has been NOTAMed since 1418Z on June 6 (23:18 local ICN time on Monday night):
A0856/16 - RWY 15R ALS U/S DUE TO MAINT. 06 JUN 18:14 2016 UNTIL 13 JUN 15:00 2016. CREATED:

It's probably buried in the several pages of unusable VOR sectors and decommissioned NDB's. And a lot of printouts are in an even more cryptic format like this:
A0854/16 NOTAMN
Q) RKRR/QMRLC/IV/NBO/A/000/999/3727N12626E005
A) RKSI B) 1606061418 C) 1609061417
E) RWY 15R/33L CLSD DUE TO ACFT ACCIDENT
The runway closure really should be flagged in the paperwork but we all know that sometimes it isn't. And, a closed major runway should always be noted in the ATIS in my opinion.
This 'I've got a secret' stuff needs to stop but it is traditional and that's the way we've always done it etc...
And of course, if you miss the NOTAM somehow, we all know who's fault it is...
If that was a Korean carrier the boys and girls would be in custody by now
It's been a while but I've worked with former colleagues of the Canadian captain of the Korean Air A300 that ran off the runway at Cheju (now Jeju) in 1994. He had to be smuggled out of the country to avoid a possible prison term.
