Wonder if anyone can advise on KVS accuracy issues, particularly with BA? I am looking to take a T-class (WT+) ticket LHR-TLV this Mon or Tues morning. KVS shows W9 E7 T6 on Mon, and W9 E9 T7 on Tues. But ba.com and every other search engine I tried are pricing up only W-class tickets.

There is no 7-day advance purchase rule on a T-class ticket that I know of. KVS POS is US but I also tried via BA's US site. Any other ideas as to how KVS can be so wrong and where I might be able to make the booking at the "right" price?
