just did some searching on th KE website, flight schedules page, and according to it, the route won't be getting the R and J seats until the last week of March, which is very strange to me since i thinnk YYZ-ICN is KE's second longest 772 route, it would make more sense to put the new seats on the longest routes, and since the iad-icn route have already started to see the new seats, logically yyz should be next. I guess we don't generate enough revenue for them here in Canada.
