But do they build their own, or buy them from someone like Boeing?  If
the
latter, then you have to assume that either a) planes don't need to be
specialized for each planet's atmosphere/gravity/weather/whatnot, or b)
that if they do have to be specialized, there's a large enough market
for
incentive.

I wouldn't think they'd build airports.  Maybe VTOL or STOL craft
operating
as "air taxi" service.	(In a similar way, I don't see a need to build a
hugely expensive road net like the US highway system.  I would expect
"hovercraft trails" would be graded, perhaps, but not paved.  Grass
might
grow there, but passing vehicles would clip anything growing too high.)
Obviously with grav vehicles, there's no distinction between air and
ground
transport, and no need for roads or airports, just  traffic control
protocol and network.
