This fare is available from mid-June then again from September through December. Departures are valid on Mondays through Thursdays, but some routes will have long layovers in Vancouver on the return flights. If you want to avoid the long layovers it is best to book October or November departures.
This fare is easily booked on Priceline.com. Other sites will jump up in price during the booking stage. I was able to find seats departing LAS on Monday, November 12 and returning from HKG on Wednesday, November 21, 2018.
