Both are affluent metros with large Asian populations, but SEA has more corporate customers (not much of a benefit right now). SEA has a larger population and higher GDP per capita than Vancouver. A fair number of puts and takes, but I'm not sure why SEA grow significantly for DL, even if it doesn't quite become the TPAC megahub that is UA's SFO
The two are not comparable. Which other West Coast hub would AC use to Asia? YVR is the only option. The US West Coast has several other options including LAX/SFO which are far better departures points for Asia. DL got the booby prize of SEA because SFO was already taken by UA and the LAX market has way more competition.
