As for the J seats, this will be 6 fewer than the already shrunken E03 config. Does the route struggle across Y as well or is it just the J cabin?
2-3-2 vs 2-4-2 means eco-flat will be too short
that low yield route struggles and with introduction of SEA, it loses SEA connection traffic. Some may even choose to go through SEA to get better seats

Note that this is not the first time YVR goes SS6 though.
