No, right now the big constraint on air travel is runways. You need 3,5, or 7 miles between planes depending on size, and that works out to one flight every minute or two per non-conflicting runway. Seattle just completed a third parallel runway, that gives them three simultaneous ops in good weather, and two in bad. Atlanta has 5 or 6 now.
