Question --
It appears that the KVSTool is returning flights that cannot be booked. I understand that any mistakes are due to the source system, but can you verify whether or not this is correct?
The relevant thread is here:

As you can see, I've found availability on EI for five business class seats DUB-BOS. The BA agent I've spoken to can see them in his system, but cannot book them because EI seats aren't bookable more than 330 days in advance.
Is this hard limit true? If it is, perhaps you could enforce a "reality filter" on results from the source, where if it returns something that you know isn't true then you don't return it to the user...
