1. AC does not oversell J.
2. C/I availability are subsets of J availability.

Are "I" and "C" separate subsets of "J" - with "I" and "C" being independent of each other. I would guess that "I" is always lower than, or equal to, "C"?

I have yet to see a case where I > C, but I have no idea if this is a rule.

Yes. "C" and "I" are in the lower bracket (often discounted) fares for business class whereas J is a full-fared business.

It is my belief (although someone will need to confirm) that you could see something like:

J9C9I6

...but where you cannot actually buy a C ticket.

Also, Rejuvenated, I'm not sure if this is what you meant, but you cannot actually buy an I class fare, they are only used for upgrades.

Sorry for not being clear, I meant in general for many airlines. CX for example treats "I" as the lowest possible booking class for business class (often in promos). For award business, "U" is their designated booking class.

Their are some things in life that just cannot be worked out or fully understood. How airlines calculate fare buckets could possibly be one of those things.

My understanding is that the J/C/I availability is controlled by the route controller, who uses historic data for that particular route, on that day, at that time of day, what are the connectors, how many people people on the connectors, delays of other flights etc. We could discuss this ad nauseum and still not come close to what the formula is and their is no magic formula IMO.

I am flying to LHR in April. For the week I need to go, all the flights ex YVR show zero availability in all economy fare classes, and 9 in JCI. I'm trying to figure out what is going on in LHR or finishing in YVR around that time.

No worries.

But even I is not always business class related... even at AC, pre-the C -> I change, I was part of the dreaded RINGPET Tango fare classes.

Exactly! Only the airlines themselves have the exact numbers in reference to seat availabilities.

So that means they don't sell more tickets in business class than there are seats? This implies that there will almost always be empty seats in business class as there will always be some no-shows. Correct?

Correct on your first point, not correct on your second.

If there are remaining unsold seats when checkin closes, they will begin to fill them up with any people who waitlisted for an upgrade when they checked in, on some routes filling the cabin.
