Seat Availability - J1, D1, I1

Not sure if this belongs here or on ExpertFlyer thread ---

If I see:
J 1 D 1 I 1

Does that mean 1 ticket available, or 3 tickets available (1 J fare, 1 D fare and 1 I fare)?
I think it's the former, but curious. If that's the case, I guess it means that for this particular flight, AA is happy to sell the last seat as an I fare? Whereas for other flights J 1 D 0 I 0 - That would be RM controlling for seats in lower fare classes, right?

At this instant it means one ticket is available. You don't know that AA will terminate J1 if a D or I-bucket ticket is sold, however.

Yep...1 seat left, and as you mentioned AA will sell it at a J, D, or I fare. If it was J1D0I0, then AA would be holding back the last seat for a full fare J ticket.

Interesting. Purely academic, but I guess you're saying that I could buy one I ticket, and it could go to J1 D0 I0, probably meaning AA is willing to oversell J?

Hes not, really. It will likely go to J0 D0 I0. J1 D0 I0 means RM has ceased selling lower fares (which may mean theyve sold the quota of discounted fares RM established forbthat flight, or certain requirements have expired - such as APEX, etc.) But AA RM is arcane and proprietary, so well not know much for certain.

Theres one seat left. J will go to zero regardless of what inventory that seat is sold from. I suppose theres a chance AA could subsequently decide to overbook the flight, but unlikely.

My understanding is that inventory classes can continue to be "available" even if there are no applicable fares such as when it's too close to departure to satisfy advanced purchase requirements for all fares of that class.

Yeah it has nothing to do with the fares that may be available to sell on that flight. Theres a very very very large number of city-pairs a pax could be booking on when looking at that particular segment. Just because there may not be any sub-14 day A/P I fares on JFK-FCO doesnt mean there arent on ORD-FCO, LAX-FCO, SEA-FCO, etc., all of which might include a leg on JFK-FCO. (Of course the airline can alternatively address this through married segment availability).

Also, someone may already have an I fare and be looking to change to that flight, which they can do even if there are no current valid I fares for sale, as long as there is inventory. If its J1 D1 I0 then they have to pay the fare difference to a J or D fare.

Also a lot of airline inventory teams may close out lower classes on full flights regardless of the current fares in the market because of potential fares. There's usually a small to large communication gap between demand/inventory and pricing teams. If another carrier files a lower fare than currently in the market, the pricing analyst may match the fare. If I is open, you might all of a sudden have a selling fare where there wasn't before.

Possible if there is a First Class cabin

Right, but it's most likely the authorization to overbook the J cabin was already factored in when the flight showed as J1. They could certainly re-assess after that goes to J0, depending on actual and expected F bookings, but I wouldn't expect it to be instant as that *probably* requires manual oversight from a revenue management analyst.
