It would be nice if BA could get its own way at its home base like AF do at CDG or LH at FRA.
Strange, I could have sworn that LHR (& all that is therein)belonged to BAA as part of Ferrovial & BA paid
rent for the second rate shopping centre with adjacent aircraft parking slots called T5. I might be wrong, but that suggests to me that BA are only tenants of T5, & its the owner really has the final say.
Then again, I suppose that if BA actually owned their own "home base" there would be more emphasis on getting passengers onto and off aircraft in a timely and stress free manner, rather than hassling passengers through aggravatingly claustrophobic transit security before soaking their wallets for spurious, expensive and innecessary purchases........
