Thanks MrSimonR - I'll check back after a while, and hope S7 is live on the BA site again!
KVS - I've downloaded/registered the KVStool now. It looks like a great product. I tried running an IKT - DME award search for 1st October (using Awards/BA-OneWorld because I'm BAEC Gold) but it shows up as "No Award Availability/Route Too Complex". Which I guess would agree with what MrSimonR is saying about the BA-to-S7 integration being broken currently...
