KE's initial plan - done by 2008 - was screwed up by 380's delay. Now they say it will be done by 2009, but only 772ER and 744 will be upgraded. They won't work on 332 and 333 even though some of those are used for long haul. Nor 773 non-ER although it is used for medium-long haul, and usually overnight (BKK,SIN-ICN). Now I can find that new config 772 will run on

June 07: SFO (772, old config on Sunday)
Jul, Aug 07: LAS (SFO will be run by old config 747 at this time)
Sep~ 07: both SFO and LAS

No idea about Canadian routes, sorry.
