Diversion policy
Whilst I don't agree with all of the posts with regards to the No Diversion policy, I did have a quick thought, taking into account MANFOD's comments with regards to inbound delays.
If Ops at Manchester are taking weather into consideration then maybe the No Diversion NOTAM would ensure that no 'fuel shortage' calls were made by inbound diversions, thus causing additional delays to our own traffic.
I will now go back to more important thoughts.
