For what it’s worth, as I didn’t understand it coming from a different airline where our allowances and pay was all paid together...VS yr 1 £4250 a month net but you wont use your net pay towards allowances like my previous airlines. Usually around $800 a month in allowances (assuming 3 trips a month on 787. Tax free.) which are loaded onto your virgin card for each trip as you depart. I usually, unintentionally, save about a quarter of that. No idea how BA works.
