Trying to book a CW ex-EU fare on BA.com but it seems to be giving a much higher pricing than the ITA sight indicates.

Details are,

1/12/07, FRA->LHR->SEA
6/12/07, SFO->LHR->ATH

ITA prices this at ~£2K, ba.com prices it at £6.7K, expert flyer only shows J/D available so am I correct in assuming the ITA sight has got it wrong?

Cheers,
Baps.
