Airport size

I have question about airports

Are they fix size or they grow with traffic?

we have

  • small airport

  • regional airports

  • mid-size airports

  • large airports

  • mega airports

if i start on small airport and bring him much more passengers and cargo, will be grow to bigger one or he stay small?

fixed sizes. whar you are probably getting at: pax is hardcoded, so are the available resources ag every airport.

But you can generate transfer passengers, if transfer is possible at the airport.
