In a simpler time, when an airline BK'd we all knew it was pax demand. With cargo, it's difficult to understand what demand is freed up by a player going bankrupt. As a result, I'm requesting that behind each airport base in the BK message there is just a simple (marketshare: 25% pax, 35% cargo) or similar to tell the world not just where they were based, but what they were doing there.
... Or # of aircraft stationed at the airports / bases
