Sounds good, but then I am guessing that SFO is San Fran, YVR is Vancouver and ANC is Anchorage. Check the same thing for a number of different dates for spring and summer this year and next to see what you see, including a day earlier and day later. You will then know how it is.
I went ahead and booked it. It was difficult to assess how "good" a fare it was because all the good fares for this year are already sold out. I was hoping to hear from others who had flown to Vancouver this year.
