Re: This is what I have come to expect from BA - keeping up their Bad Attitude nickname!
I have noticed a trend for one or two of the lavatories to be out of order during flights on several airlines. I suspect it is cost cutting by reducing cleaning costs and, more importantly, turn round times. The "out of order" lavatories are clean and can be used on the return flight.
I don't fly often enough to make a study and come to a significant conclusion. Anyone know if I am correct?
