Last I heard, at last ACDL and LBC were talking again.
Expect the 'Master Plan' to be well contained within the current perimeter of the airport. Fancy ideas of new runways were fantasy!
Ferrovial are busting a gut to refinance their BAA purchase debt in a worldwide economy that now detests large investment. ACDL, also Spanish, must invest lots of money to enhance Luton, but as I have said before, they have to ensure the concession period allows them to recoup the capital investment which means re-negotiating the deal length with LBC.
LBC cannot extend the 'deal' without puting it back out to tender. Hopefully the impasse has moved on?
