Protected connections from Harbour Air to AC are something I've been hoping for for some time. Once HA redemptions become available, hopefully AC considers the floatplane terminal and YVR to be co-terminals. Certainly a lot easier to get between them than JFK/EWR/LGA.

If redemption costs aren't insane, I can see my company buying Aeroplan points in order to book itineraries with both Harbour Air and AC on them, as presumably these will remain unavailable with cash bookings.
