Is it not true that last summer BA had mountains of peoples baggage,that they shipped them by containers to Europe to be sorted ? So, we should not be too surprised that BA struggle to carry pax & bags on the same flight.
Is it also not true that BA are the world leader in "ghost flights", where longhaul aircraft operate, but without pax? What happened to those halcyon days of BOAC ?
Since BA dumped on the regions, most of us north of Watford rely on KLM, Lufty, Emirates etc to get us where we want to go. You're welcome to BA / T5 - its all yours.
