Outward is easy via YVR...You get Through Baggage Check/Transfer with just a few minutes at the Immigration for ID check and then Fastrack through secret corridors [Taking Option 1] to Departures. Details here:

However on the Return MEX is better as no Baggage Collection and Transfer, Immigration and Customs. However much depends on where the OP lives.
PS. New BA Club World Business Class upgraded seats etc. to be announced next week.
