As mentioned in the KVS Tool User Guide (
http://Help.KVSTool.com/#Methods), [ITA: Awards-Upgrades/X1] cannot show flights, which are zeroed-out in the Economy cabin (e.g. Y0).
UA 932/24 Dec is Y0.
UA 974/24 Dec is Y9, but all possible return flights (26 Dec) are Y0.
What else am I not understanding. I missed that note in the help section. That is good to know.
I understand UA932 not displaying because of Y0.
However, I do not understand UA974 not displaying since it is Y9. What does a return have to do with it?
Also, I have noticed quite a few flights where there is major NC availabilty but it does not show up on KVS because it is Y0. Seems like UA might be making a point.
