In-Game Demand Data update this year

Hey everyone,

I was just a bit curious about which airports are likely to see major changes in demand later on this year and when they do change, how is the demand of each airport going to be calculated? Is it through total passengers in the last year or so? Will it be like 20 million passengers for an 8 bar airport and roughly 35 million for a 9 bar?

Looking forward to changes!

Billy
