WTP to CW from LHR - LAS on BA275 on 28/12 was being offered at an eye-wateringly expensive £1135 at both NCL and LHR. Even the staff thought this was ludicrous. The flight was relatively empty which may explain the high pricing. Suffice to say that I didn't partake and so our daughter was in WTP while we enjoyed the UD having already UUA at the time of booking
