If I were a suspicious and cynical chap, I would think that BAA was doing little to prevent the switch in services from LGW to LHR. After all they are having to dispose of LGW so why leave it with a traffic base that could / would challenge its main earner (i.e. LHR)?
Don't get me wrong, I know that the likes of DL, US and CO have long covetted the prospect of operating out of Heathrow, but it would seem that slots are being found for them at one of the most slot constrained airport in Europe? Amazing what can be done when the corporate body puts it's mind to it
