If BA ever needed reminding that having all your eggs in one basket was a dangerous policy then surely this summer's chaos that costed BA £100 million is surely that lesson. It is interesting to note that whilst LHR, LGW & STN all suffered, most regional airports were able to 'manage' the disruption without the mass flight cancellations.
BAs withdrawl from the regions seems to have missed this point.
Good luck to everyone at BAcon!
