Korean Air Skypass - How to tell which version of 777-300 on a particular route?

KE seems to have an old 777-300 and a newer version.
How do we tell which version is on a particular route?

Thanks!

Have you tried looking it up on Koreanair.com, "Onboard", "Flight Schedule with New Aircraft"?

I looked up the flight on that flight schedule tool but the flight doesnt show up.
Does that mean it's an old aircraft?

It's flight 641 from ICN to SIN in September.

What's the exact date? EF shows KE641 in mid-September as a 773 with J inventory (instead of C), which should indicate that it's the Prestige Sleeper seats.

Im looking at Sep 10 from ICN to SIN for KE641.
There is an earlier flight which is the 777-200 with nice seats.

The later evening flight(KE 641) has a better schedule but seems like an old plane.

Thanks!

KE's older 777-300's are all fitted with new seats now. the newer 777-300's i think u are referring to the 777-300ER

Would KE 641 then have the full lie flat Prestige seats or would it still have the slanted version?

Thanks
