BMI wants to be in LHR in own right I'd reckon, rather than hanging on Sir Dickie's coat tails - or perhaps have VS do the MAN runs while BMI got the tasty LHR traffic.
Sir Dickie may look that dumb, but he ain't. With BD linked to VS and UA, BA and AA would demand a proper linkage currently denied them due the protests of, among others, BD and VS.
Thus VS+BD full link up is a ways away methinks.
methinks this may also be post 300 - wheeee!
