Steady on chaps
My reading of the situation is that NATS are doing forward planning in case air travel over the UK grows as some forecasts suggest.
Now what else would you expect (and require) a professional organisation charged with handling air traffic do? Sit on their hands?
NATS has no more control over the amount of air traffic than I do, they are just lumbered with handling how ever much market forces cause.
I would expect correspondents on this forum to appreciate that.
