This thread refers specifically to Blackpool Airport and its 'decision' to ban an authorised long term operator to operate from that Airport.
Seems the correct place to run the discussion.
But most posts aren't discussing BLK (e.g. #37 immediatley after yours). As an aside, many airfields ban banner towing because of the difficulty in integrating into other traffic (mine does), it may be that case is the straw that broke the camels back and they finally decided it was more trouble than it was worth?
