Whilst the report is produced by Ferrovialand cannot be impartial, it I don't don't that the conclusion is correct.
Fortunately, everyone can stop worrying if LHR is going to lose out since the battle is already lost. The time to allow the third runway was 20 years ago. The big europe hubs, the middle eastern hubs and carriers, have all take the lead. It may only just be showing up in the figures but the war is over.
A pity, because it could have been different.
