The only problem is that ... nothing is gonna change.
At the big locations, the myth of retailing cash will hold sway and, besides, for the money men it's more fun than aeroplanes.
At small, regional ones, they might try the small is beautiful approach but it will be an uphill job.
Unfortuantely, we have all of the new terminals that we are going to need for the next ten years (forget LHR 6) and the next round of opportunities in this country will be after this (very bad) recession. If someone needed to build a terminal now, they would probably still go for the shopping mall because they think it will bring in money and, to a degree it does. The cash flow is there - what cannot be proved is how much people would like the place if it was not there. You have to prove a negative. Lastly, those who like and dislike shopping, is only the regulars that dislike it? Do the occasional travellers like the shops?
