Did a search and could find anything on this. Looks like on 2JUL2005 KE will start using B777 on their 2nd flight ICN-JFK-ICN on Sun/Mon/Wed. Other days of the week (except Thu..no op) will be B744.
KE 85 departs ICN 1850 arrive JFK 1930
KE 86 departs JFK 0050 arrive ICN 0420 +1
It'll be nice to finally see something other than the normal B747-400 on a regular basis at JFK.
