Its prestige plus as of now, but SEA-ICN and IAD-ICN which are operated by 772s have both just got the lie flat seats, i bet i won't take them four months to update all of the 772 routes.

here's the offical KE link if you haven't seen it yet.

When i flew it a few years ago, they gave out amenity kits, but i've heard some reports suggesting that's no longer the case. they flight leaves right after mid night, so no meal before going to bed, but there's "dinner" when you wake up. Crew's very friendly, and IMO pretty good looking. When are you taking the flight, please report back the type of seat you got. I've got a flight next Feb, and i'm dying to know whether i'll get the lie flat seat or not.
