So, just out of curiosity, does anyone here know if it is possible for an airline to own, outright, an airport? I imagine that would cause some trouble with anti-monopoly laws, but I'm not sure.

I was just musing over the economics of such an operation - if we assume that most airports make money, and the economics of an airport could generally be improved if everything was streamlined to one airline's operations (a la T5), wouldn't that make some sort of financial sense?

Oh, and then the airline couldn't shift responsibility for closed runways to the 3rd party owners
