Well, Korean Air's Prestige class is nothing fancy like lie flat seats... but is a decent product. You get a typical J seat with 50" of legroom and a classic PTV (no AVOD) is available... Meals are their strengths... very nice presentations -- course by course... the lounge at Seoul is amazing.
Compared to EK
's business class, I think KE
is not too bad... EK
has the fancier business class seats on the Airbus A340-500s, but still no flat seats... and I think KE
's F/As are a bit more consistent and friendlier than EK
is good, but the F/As really vary from flight to flight... sometimes friendly, but sometimes downright rude... KE
is more consistent...)
Enjoy your KE
flights... more miles sound like a better deal in this case...
