J9 indicates the availability with respect to the fare bucket. Ranging from 0 to 9 (does not go any higher), so there are at least 9 tickets available at the J fare bucket, highest in the class cabin - full fare without any discount.

I've always wondered why they don't list the actual number ... instead of "9" as the max. Legacy software?

Its a pretty fundamental limit, though; a party of nine can buy one PNR via the website or a travel agent; you can use nine upgrade certificates to upgrade them; a Platinum or higher can guest everyone into E+, etc. Party of 10? You have to call group sales, premier benefits dont apply, upgrades are difficult / impossible to use, etc.
Its all tied to the same basic design principle.

Has this functionality been temporarily removed? I can't see the buckets on the web or my phone. I re-verified I have expert mode enabled, even disabled and reneabled it, but it's not working. Can someone else comment?
EDIT: It works if I search cash fares; it does not for award searches. I swear it used to work when I was doing award searches.

It's been several years since it worked on award searches. Originally it worked on all searches, then it was broken for a while, and then they brought it back on cash searches only.

Anyone else having married segment issues when the flight starts with a 1-cabin plane?
Case in point, if I search from my home airport, which the flights invariably begin on a CRJ to ORD, and I select EWR as my final destination, the fare buckets look like this:
First segment on the 1-cabin Devil's Chariot: Available fare classes:Y0YN0B0M0E0U0H0HN0Q0V0W0S0T0L0K0G0N9XN0X9
Connecting to ORD-EWR: Available fare classes:J0JN0C0D0Z0ZN0P0PN0PZ0IN0I0Y0YN0B0M0E0U0H0 HN0Q0V0W0S0T0L0K0G0N9XN0X9
Searching each flight individually:
First segment: Available fare classes: Y9YN9B9M9E9U9H9HN9Q9V9W9S9T9L9K9G9N9XN9X9
Connecting to ORD-EWR: Available fare classes: J9JN9C9D9Z8ZN8P5PN0PZ0IN0I0Y9YN9B9M9E9U9H9HN9Q9V9W 9S9T9L9K9G9N9XN9X9
It's not actually a married segment issue, I don't think, because when searching together, despite most fare buckets showing -0-, all 4 options (Basic, Regular Economy, Flexible Economy and First/Business) show various booking classes when clicking through (N, G, E and P, for the 4 options, respectively). Also, if I search between 2 airports where connecting as well, but on 2-class aircraft the whole way, this doesn't happen. Something's happening that united.com doesn't like when it's a 1-cabin starting flight. Also, on the return flight home, 2-cabin then connecting to a 1-cabin, it displays correctly as well.
Kind of annoying when looking for a cursory upgrade chance to see nothing when it comes to expert mode.

The advice has always been to look for upgrade space on segments individually from point to point - UA will price the itinerary correctly, but at least you know if you can run the upgrade request after ticketing and clear.

...Yet more egregious is that when it's a 1-cabin flight followed by a 2-cabin flight, it's showing darn near zeros for ALL cabins, and as I said above, including zeros for the multitude of fares it actually offers you (N for basic, W/V/S for economy, a higher one for unrestriceted, and a first fare, whether it be a P, Z, C, J, etc).

Mixed cabin used to bypass married segment control, which could be very useful if there were suppression rules for through inventory. A good example was SFO-EWR-DCA would suppress J space if EWR-DCA was two-cabin but if taking an E45 it would use broken inventory (sadly, flying nonstop from IAD in a recliner was usually the better choice anyway).

Sounds like an issue with Expert Mode rather than inventory then?
