Sure. I'd like to see a fleet of super planes, massive flying wings that carry thousands and have malls and lounges and whatnot. Powered by fusion reactors or power beamed down by orbiting solar satellites, these behemoth would never land.
Docking collars in aerodynamically stable areas would receive small commuter planes from airports within range of the behemoths path. Planes would climb, match paths, intercept some type of ILS, and hold themselves in position, maybe with the aid of some collar. Passengers would debark, any passengers heading to whatever airport the feeder was going to next would board, and then the plane would leave, making room for the next one closing in on the giant.
Once onboard, passengers would either go to cattle style seating or purchase inflight entertainments of different types, stuff like that.
Maybe these planes are modular. Big flying wings that link up to provide larger structures in air so that, when needed, any segment might detach and land at some large airport set up to receive it. Bigger segments (such as those that have malls and other revenue structures, or reactors) might land at places like Palmdale with easy approaches and big, long runways.
Some day in the future, I'll meet y'all at 40,000 feet at the big bubble glass sundeck atop the Grand Pacifica somewhere between Japan and Seattle. We'll meet by the fountain.
