why?

I didn’t realise I had to get your permission!?!?

Seriously though, it was just to get a rough idea of how good a route was doing – no guarantee of profitability of the service, but still useful to know. In a similar vein, I spent almost the whole of summer 1994 going to MAN twice a week for 8 hours plus, and worked out back then that something had to happen with regard to a nrew runway and/or expanding the peak period as I was coming up with anything up to 50 movements an hour up to 10am on a runway capacity limit of 42 per hour.
