I get that I am beating a dead horse here but the fuel provided for both the A and the B is 19,932lbs. That is what the A version would have had available. The B would have had a little over 33,500 available at max fuel as it had larger tanks to provide those trans-atlantic flights....and it did still need to make a stop or two on the west return flights from Europe. If you wish to make those flights across the atlanitc make sure you make yourself available to reset the fuel load manager mid flight (not the most realistic manner but the best you can do at this point).
