Excellent piece in The Times the other day pushing for big user price hikes at LHR as a means of reducing demand and getting the airport back to working within its capacity... worth a read, but unlikley to find favour at BA.
This must be the most cobard way of dealing with problems, what you do is plan ahead , imagine if I started a new route between LHR and DXB on a A321 configured in full charter seating, and then once I notice that we won't we making it there with all the pax that bought a ticket I decide to only take those that pay more. Imagine this happens for over 10 years....
