It’s also the airport layout information, including doors. From most US airports, you specify your pickup point by door (Arrival E6, for example), and I think some of that information lives in the app, along with the snap points that are rendered on the map (or even just the logic). There’s usually also a specific UX when requesting the ride where it asks you to select your airline to guess which terminal and egress to set as the pick up point.

Why would airport layout data not be handled the same way as city layouts? Maybe effectively automatically caching airports to make up for potential bandwidth issues?

And for the specific UX, sure but isn't that just a single feature for airports in general, and the app can pull the up to date airlines/terminals data for the specific airport when needed?
