My experience of BA is that we don't do base training on our longhaul aircraft as the pilots that join us directly to fly them have already met the "minimum hours in a similar class of aircraft" requirement.
All our sims are ZFT, however we do recruit pilots onto the shorthaul fleets (Airbus, B737 and B757) that are required to go off and do the base training to meet CAA requirements.
The only recent exception was Concorde which was not a ZFT sim and thus required circuits and bumps to complete the type rating. Try paying that fuel bill.....
