Yes but only seasonal barely once a week. SEA for example has once daily with both DL & AS to MCO year round, so if SEA can have that service, AC can make YVR-MCO viable daily too. The issue is that there is leakage to SEA from Vancouver because AC doesn't provide the service that DL and AS do from SEA. I'm not asking a secondary US city from YVR, Orlando is a global tourist destination and you got flights even from DXB that are viable so international traffic is up there.
This is why I'm confused as to why AC doesn't add a YVR-MCO or YVR-FLL flight, you don't have asia pax but australia/new zealand pax too that can easily connect. YVR has secondary asian cities that SFO or LAX doesn't have and it would be nice to have a MCO option out of YVR too. I get those living in Vancouver can drive down to SEA to catch a direct MCO or FLL flight but YVR has so much potential for connections pax and AC doesn't use the airport to the fullest. Heck even YYC has direct flights to MCO thanks to WS, it's just sad that it's so difficult to get to MCO or Florida out of YVR.
WS does fly from YVR-MCO now. But the market isn't huge. The leisure market from YVR is far more geared towards California, Las Vegas, Mexico and Hawaii, while Florida is more popular with Easterners. The connection traffic YVR can provide that is drawing passengers away from LAX and SFO is more geared towards places like JFK, EWR and ORD. And that's where they can pull business class connecting pax.
I believe it's year-round once weekly according to the WS website. Which fits with 7 day holiday packages.
If there was a market, I'm sure it would be served already. But MCO is a lower yield AC Rouge destination and AC has almost completely removed Rouge services from YVR. Even Sunwing and Air Transat don't fly to Florida from Vancouver. And Florida isn't needed for Latin American connections either, YVR uses LAX or MEX instead.
Yes, Orlando is a big holiday destination for Americans and Europeans but I am not fully convinced it's a major leisure destination for people from Vancouver. And I'm not convinced there is enough Asian or Australian travellers going to MCO via YVR that would merit AC adding this service. But maybe I'm wrong, and maybe there are stats for how many YVR-MCO connections are searched for.
