although BA used to fly a split load on LGW-MAN-ISB from 44 on the B744 as I recall
And lets not forget the days of the bmi base where there were 3xA332, as well as the BA and AA B767's. Granted they didn't have 7 based Ryanair B737's and well as the KLM/Air France flights which are a B737 and A321 respectively to contend with however....
