If all BA pax who where fed up with T5 and BA in general started flying with bmi, Virgin ...
It is definitely happening. A colleague here in Dubai (a Gold Exec Club Card holder) was due to fly Biz class tomorrow with BA to T5, but decided not to take the risk of bags not arriving in good time (!).
Just spend an age on a VERY busy Virgin Atlantic site to book Premium Economy with them instead. Strangely, this Gold Card holder is also vowing never to fly with BA again. I doubt whether that statement will hold true, but it is definitely true that (from Dubai at least) Emirates and Virgin are most definitely scoring big, thanks to BA's own goal.
