I understand the mechanic's intent, but we may need a mod that allows an encampment to be upgraded with a building inside for planes, rather than a whole new District.
Now that we've seen more of this game, we know with a certainty that getting cities super, super big will be tough, and, for example a 20 population city only gets 6 districts (with the caveat that a Civ's Unique District doesn't count against the limit, I don't think, and maybe a few other curveballs). It's a major blow to "something" in your biggest cities if you have devote an entire district just to build a handful of plans. That's a sacrifice of something very important.
If you look at the core districts that you're going to want in your big cities, you have: Campus, Encampment, Commercial Hub, Industrial Zone, Entertainment, Theater Square, Aqueduct, Neighborhood, and depending on strategy, holy Site.
That's 8 core districts, and potentially 9. You're telling me you want your biggest cities to forego something critical just to Store planes, let alone build them? I don't believe it. Unless planes are crazy OP, I'm not building planes unless an encampment improvement is sufficient to allow me to. You only get to store them in the city with an Aerodome, and unless they can reach 10+ tiles, that's basically just a turtle mechanism if you're defending against a swarm.
I think that's going to need a change.
Edit: I should add (as I also do below), that the Airstrip improvement that can be made outside your borders changes my opinion a little bit (Thanks to SilverDawn). I still think Population growth will be a problem to get sufficient so that you won't miss a district you're giving up to build aerodome, but at least airstrip placement beyond borders looks like it could solve the storage problem. So, I add that caveat.
