Something similar in concept to a river could be developed. A linear way for the the routing etc (waterway), and an area to indicate the outline of the runway/taxiways (riverbank).

I always map them as closed polygons because:

 * It's more accurate
 * Runways aren't necessarily rectangular, Some have bulbous turning
   circles to come back down the runway, rather than a one way taxi
 * Even grass strips for microlights render very wide in Carto when
   zoomed out.

Please don't let whoever changed the wiki to read 'runaway = Runway of an airfield' ever compile a dictionary

    Well, maybe there is someone who thinks mapping runway as area is
    wrong? I think that both way and area are OK, because the way
    element matches the way we map taxiways. So it is useful when
    others need to guide their plane using osm data(maybe in flight
    simulator softwares). Mapping as area can show the width of the
    runway and thus is more realistic. The best method should be using
    both elements. Just like highway objects. Obviously, the wikipage
    needs some edit or restoration.

Map the runways and taxiways as linear (who knows, someone might want to have a routable model for flight simulators or similar games), and map the negative space (grass infields, etc) as areas?
