This. It's why the Europe Latitude price comparison isn't fair, as the 'market' ones listed by the OP were likely for a r/t. Price it one way, and it's a completely different story.
As for high-flex/low-flex, the big difference is availability. YYC-SFO within a week rarely has low flex, so a high-flex pass gives good pricing compared to what would actually be bought.
I bought a Southwestern 20x Latitude pass 10 days ago after the price for two people to attend a meeting with me in SFO on short notice was $3500. Makes the remaining 16 flights pretty darn cheap.
