Trying to search for Incheon-Las Vegas flights at the end of June.

Realised that Economy seats are showing up, but while searching for Business and First seats on operating days, KE005 does not show up as an option. On further investigation, it happens on various dates at the end of June and early July.

Interestingly, on the days when KE005 (ICN/LAS) are not an option, KE006 (returning LAS/ICN) is operating.

I don't think it's an issue of Business or First being sold out as it is an issue on multiple dates (sometimes for all 5 days the week).

I think when they uploaded the seat plans for 77W with the Kosmo 2.0 (replacing the Kosmo Suites) into the system, the website has trouble accessing the inventory.

Have written to KoreanAir, hope they fix it soon.
