Fare Class has Inventory - Not Able to Book into?

Common issue
Expert Mode shows ..... T9, L9, K9, G9, N9 but you not able to get united.com or other sites to provide a fare for N or G or .... WHY?

There are three requirements to be able to book a fare class
1) there needs to be a fare rule for that fare class for your O/D.
2) you need to meet all the requirements for the fare rule -- advance purchase, days of the week, min stay, qualified flight numbers, qualified routing (including a possible RT requirement), .....
3) there needs to be inventory in the fare class

So if the cheapest fare rule filed is K, you will not be able to book N or G
Even if a fare rule is filed and there is inventory then you still need to meet the fare rule requirements.

As for searching, if multiple fares qualify, the cheapest will be displayed unless you specifically force a fare class. While the fare hierarchy will generally match the cost, occasionally a high fare class will be cheaper than a lower fare class due to differences in fare flexibility such as refundable, changeability, ....

So there are multiple reasons for why a specific fare class is and not is offered. Confusion on this is one reason UA has been reluctant to make fare class inventory easily available and the reason UA requires one to accept the following terms before providing access to Expert Mode:
This is not a forecasting tool. Availability levels in certain fare classes should not be interpreted as indicating that we will make other fare classes available.

The presence of a particular fare class does not mean that there is a fare associated with it. For example, we may offer availability in a discounted fare class, but that does not necessarily mean we have published a fare that corresponds to it.
How can you see the fare rules?
While booking (on the first "Review trip itin" page) and after booking (on the online view of the reservation) , UA will makes them available -- but this is only if UA will display that particular fare.

Before booking or if unable to get access on UA, there are paid services -- KVS, Expert Flyer. ... can provide access to all published fare rules.

Doesn't work with most airlines, but UA does seem to have a bit more flexibility sometimes
That's not possible on the same PNR. Expert mode doesn't have any bearing, by the way.

The only way to do this, as with other airlines, is to book two separate PNRs. You cannot do it on a single PNR.

Figured as much. Thanks.

Can they do it over the phone? AA used to be able to do it on the phone

as separate ticket, yes

For ancient reasons, an industry standard multiperson ticket, common ticket only has a single entry for ticket details: to, from, routing, fare, fare classes, ... so it is impossible to have different traveler ticket details.Some travel agents will issue a PNR with multiple tickets -- that is no longer the practice of the majors, it can create issues and does not offer the protection of a single ticket.

no, AA, nor any other airline, can or ever was able to do this. The only exception that I can think of is for certain discounts like for child discounts, but even those are booked into the same fare class, with the child charged X% (say 70 or 75%) of whatever the fare is, and those are embedded into the fare rules as part of the tariff when applicable.

In order to be on the same PNR, all fares need to be the same fare class. If AA ‘did’ this, they simply booked you on the same phone call, under two different PNRs.

following up on this UA loaded L fares for this route in the last week.

Trying to book a trip in October for a friend HNL-SFO-DEN (avoiding redeyes). UA is providing options where HNL-SFO is in K but SFO-DEN is in S, the SFO-DEN flight is currently T9 L9 K1. When I attempt to book these separately it gives me the K fare on both segments, however I can't get it to price this way when booking a through ticket. I don't see anything in the fare rules that states S is the cheapest I can take in conjunction with an HNL flight. Any help is greatly appreciated.

Can't say for sure without a date, but it's very likely UA doesn't publish a K fare on that route.

It's a combinability issue of some sort, although I can't quite puzzle out exactly what.

As an example to others, consider 18-Oct-21 and HNL :: UA372 SFO UA1790 :: DEN

This will price substantially lower when splitting the ticket in SFO, as the lower SFO-DEN fares seem unwilling to price in combination with GAX5LKEN on HNL-SFO.

OK, so I think what's happening is this:

The HNL-SFO fare would be combinable with any SFO-DEN fare on UA. However, the cheapest SFO-DEN fares are not combinable with an HNL-SFO fare unless there's a stopover at SFO.

Here's the end-on-end combination section for SFO-DEN on a K fare. I've bolded relevant passages.

UA doesn't appear to publish 4th Level Economy Unrestricted fares between HNL and SFO, and, if they did, a K fare wouldn't be 4th level -- it'd be 7th or 8th level. So, the first rule doesn't help, and you proceed. The rule and tariff conditions for the other block match, but it's requiring a stopover. That's why you can get two K fares if you have a long enough layover, but it upgrades to K/S for convenient connections.

I won't bore you with the L or T fares -- suffice it to say that I spot checked a few of them, and they all have the same restriction, as does SAA3OWEN, a cheaper S fare.

Here are the rules for SAA1AKEN, which combines successfully:

The K fare for HNL-SFO is in tariff DFR, and they've removed the stopover requirement. Therefore, this S fare is combinable with the HNL-SFO K fare, and that's why this combination will price while the others won't.

Incidentally, Kacee is correct that there isn't a (one-way) K fare published on HNL-DEN. Excluding 60-day advanced purchase fares, which aren't useful for October travel, the cheapest through fare is a V, which is why it's coming up with these broken fares in the first place.

OP: You can try multi-city search, but since this is a combinability issue, not an inventory issue, it's unlikely you can evade this rule. You could purchase separate tickets, but understand that a flight delay out of HNL could make it very expensive to get to DEN -- you might end up needing to pay the walk-up fare.

jsloan , you should go work at the Rate Desk. (!)

Wouldn't it be possible to have a four-hour (or longer) "stopover" on a single ticket, and then hang out at the United Club?

😊 Thanks for the compliment. Fortunately, I enjoy my day job too much to want to do that.

Probably -- although UA wrote in a "no stopover occurs if you take the next flight within 18 hours of arrival," it doesn't appear that their pricing engine noticed -- it's allowing the combination as long as the transfer is longer than four hours. The problem is going to be scheduling -- OP wanted to avoid red-eyes, and it's not possible to get the four-hour layover without either a redeye or an overnight stay in California.

Someone with status could book the long layover and attempt a same-day change, although K inventory hub-to-hub doesn't seem like something that would be plentiful.

UA doesn't appear to publish 4th Level Economy Unrestricted fares between HNL and SFO, and, if they did, a K fare wouldn't be 4th level -- it'd be 7th or 8th level. So, the first rule doesn't help, and you proceed. The rule and tariff conditions for the other block match, but it's requiring a stopover. That's why you can get two K fares if you have a long enough layover, but it upgrades to K/S for convenient connections.

I won't bore you with the L or T fares -- suffice it to say that I spot checked a few of them, and they all have the same restriction, as does SAA3OWEN, a cheaper S fare.

Here are the rules for SAA1AKEN, which combines successfully:

          OAK-SJC  ONT-SNA  SFO-SJC
The K fare for HNL-SFO is in tariff DFR, and they've removed the stopover requirement. Therefore, this S fare is combinable with the HNL-SFO K fare, and that's why this combination will price while the others won't.

Incidentally, Kacee is correct that there isn't a (one-way) K fare published on HNL-DEN. Excluding 60-day advanced purchase fares, which aren't useful for October travel, the cheapest through fare is a V, which is why it's coming up with these broken fares in the first place.

OP: You can try multi-city search, but since this is a combinability issue, not an inventory issue, it's unlikely you can evade this rule. You could purchase separate tickets, but understand that a flight delay out of HNL could make it very expensive to get to DEN -- you might end up needing to pay the walk-up fare.
Thanks for the help, I knew I was missing something when I was reading the fare rules.

We did try to price it as a multi-city but it still kept the same price as the through fare. I could maybe try Multi-City with the SFO-DEN flight the following day (creating a stopover) then changing the second leg to the day before, that could work but for like $60 I am going to say it isn't worth it and they don't want separate tickets

Cheapest fare on sale = L, but available fare bucket has K3, what would be the rationale for this?
