I'm a Diamond user. I am having problems searching for IB availability ex-MAD using the tool.

The BA web site (and AA.com reservations) show availability on a leg MAD-TLV in Y. The KVS tool returns the applicable flight, but lists them as CS+ with no entry for Y (not even YS-).

I've found this to be true on a number of other IB and BA flights, where the tool doesn't even indicate Y availability.

Is this a known bug? What can I do to fix it?

Thanks!
