We booked our flights last week from Seattle, direct on Alaska for March 4-14, and it was $1300 CDN for 3 of us. About the same as we paid 2 years ago, actually. The flight from Vancouver would have been $2500, and it was just going down to Seattle to connect to the flight we actually ended up choosing.
The price difference is amazing...even when you factor in the cost of hotel in Seattle (if needed) and parking, it's still worthwhile.
I haven't seen much cheaper than we got for March, but we also want non-stop.
Now car rentals are another story...the rates seem to have gone waaaay up since our last trip!
