You should look up fares before making guesses like this..... plus the Z fares YOW-YVR carry adv-pur of anywhere from 14-30 days. The walk up C fare is $2235 ow. The LMU program is very successful
I always note down the all-in price of Z at the time of my booking.
If LMU + what I’ve paid work out to ≥15% cheaper than the all-in price of Z fare at the time of my booking, I’ll consider it to be a good deal.
