What's the 777 that you got? If it's the 2-2-2 config, that is still direct aisle access Prestige Suites, same seating (though less roomy) than on 747-8i. If it's the 2-3-2 config with the older Prestige Sleeper (https://www.koreanair.com/us/en/in-f...r-291/prestige), that's a product that's not really competitive anymore.. but the middle seats usually go empty, so unless it's a packed flight it's still OK, just obviously no real privacy.
