I know and I'm based in Seattle, well 50 mins from Sea Tac, I have been pricing approx dates all this year for October and every time YVR has been significantly cheaper hence make the two hour trip up the road to Vancouver, but now fares have flipped, some crazy prices out of YVR, so it might be a case when my plans are firmed up we will go with SEA, will be nice to fly in and out of Terminal 5 at LHR
