When using Pack, Airport 3D View imagery is saved for offline viewing only for the airports in the route.
To save Airport 3D View imagery for other airports along your route, either view them separately before your flight (from the Airports page, or the Maps page) or add those other airports to the route and Pack, then restore the original route.
Example: Tap an Airport icon on the Maps page, then choose 3D View.

NOTE: The app’s “cache” of the 3D Aerial View imagery holds 20-25 airports worth of data. Once the cache fills up, as you Pack for a route with a new airport (or view a new Airport 3D) the data for airport(s) that have been in the cache the longest will be cleared-out to make room for the new.
There is no way to designate “always available” airports, so we recommend using Pack before a flight with a route that includes ALL the airports for which you would like to have the 3D Aerial View available while in-flight.
