Connectivity at airports is not the best - if you’re on an expensive data plan those extra MBs cost a pretty penny which might put off the customer.
You need to think about the larger picture.
You need to think about the larger picture.
Thinking of my experience with Uber at airports, it's generally stuff like "pickups from this terminal are only available at the west exit" (show on map - so needs coordinates and message text), or "There is a £10 airport pickup fee for all private hire vehicles here which will be added to your bill", or whatever along those lines.
But perhaps your point still stands even if it's KBs rather than MBs.
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?
A quick summary like "extra fee for airport pickup: X, pickup location restricted to: Y, etc." should be pretty comparable.
