The second thing we learnt was that many in the industry are getting angry about the claim, often made by lobbyists, that Britain's airports are full.
"We're not," said one airport executive. "Gatwick has loads of space at the moment, so too do Luton and Stansted and they've just opened a new terminal at Southend. Saying 'Britain is full' all the time is putting off new airlines from coming here."
I do wonder who this so-called executive is?
There is less than 2m pax of space at LTN. Full of bottlenecks such as a short runway, unusual apron setup, no full length taxiway all in pretty cramped surroundings as airports go.
STN has some space; in the short term they have been haemorraging airlines, but in the long term this space is set to be taken up - they've been looking for a second runway of course.
LGW is the busiest single runway airport in the world; not an airport I've travelled through or studied extensively, but 34 million on one runway seems pretty busy! How much excess capacity is there?
