Hey...don't appologise Cyrano....I accept largely what you are saying.....
Phileas, I was pontificating,were this to be an Easten Airways route instead of a charter, (in very broad terms) the sorts of costs and revenues the airline would face.
The load factor bit ?....well ...To me, Eastern are a niche player...quietly keeping out of the way of the big boys and charging high fares......hence they only have to fill their planes half full.
