Kerling, why would we get delays? Having retired from the heavy stuff I now fly a medium twin into some of the busy spots in the US , at these places one sees a traffic mix never seen at any of the major Brit or EU airports, so if they can do it, why not you folks? As for N numbers having a few problems, we see a bit of this but its our own fault for having two official lingos in our ATC system, seems to worry them. Having said this, with the run down of the RAF and Britains lack of snow shovels the traffic should be a lot less this winter.
