I'm flying to Okinawa next week for work, and I'm thinking of flying Korean (via KIX). I thought about paying the difference on my full Y fare to First Class, just to try the F lounge at ICN. I was wondering if anybody could fill me in on the product.

Lounge is good I read. Up in the air do they serve Dom in First for short-haul? Anybody had any experience with F on this short flight?
Not too worried about seats, as it's only an hour-and-a-half long....
Kamsa-hamnida!
