I'm trying to book tickets from SNA/LAX- KIX

In November. KVS shows F9. etc... 9's all across on every fare.

But when I use KVS and show fares it only pulls up V as 740 dollars....Is there anyway I can force S or T booking class to show up

I'm doing this as part of a mileage run to plan on getting 1P (with the hopes of the double EQM poping up)
