You forgot to mention that occasionally you may see a date as available for your route and class through the 3-day scroll, but once you click on the specific date, no options are presented.
Cathay’s system is horrible.
I think I usually see 5 days on top of the screen to tap on, usually without availability and required number of points in calendar itself, like this screenshot. I don't think I've ever seen '3 day scroll', however I've occasionally seen 5 day calendar with either 'not available ' or 'from xxx miles'. In my experience, they've been accurate, when it says there's availability, I can proceed to check out.
When I search minor city pairs like YVR or SEA to PNH, it's a lot more problematic. Google shows CX sells (and presumably flies) HKG to PNH 3-5 days a week for next 2 months, but whatever the date I choose, I get a series of errors. First with this 'processing' for 30 secs:

Then it shows this message by itself for about 10 secs:

Then finally this. This whole cycle takes at least 2 min, so if I were to diligently check everyday for a month, it takes at least an hour.
