The Pack feature only stores satellite imagery for airports specifically listed on the route, so only those airports benefit from Airport 3D View while offline. But there are two ways, described below, to enable Airport 3D View for additional airports: either pack additional airports from the FPL editor or view additional airports before flight.
Option 1: Pack Additional Airports from the FPL Editor
This method involves creating a route to be listed as a recent route, then creating a new route made up of only additional airports, packing, restoring the original route, and then packing for the original route. It ensures that ForeFlight stores satellite imagery for all the additional airports in its offline cache, but only presents the intended route of flight.
STEP 1. On the Maps view, construct the intended route of flight in the FPL editor. When done, the flight will be listed in the recent routes list (found when pressing the button that has a star and clock).

STEP 2. Clear the route from the FPL editor by selecting the Clear button.
STEP 3. Use the FPL Editor to add airports you want to see in Airport 3D View during the flight.

STEP 4. Select the Pack button (looks like a suitcase) in the FPL editor to store Airport 3D View imagery on your device for offline viewing.
Packing with Additional Airports
STEP 5. Tap the Recents button (has a star and clock) to restore the original route for use in flight.

STEP 6. Select the Pack button (looks like a suitcase) in the FPL editor to store Airport 3D View imagery on your device for offline viewing.
Option 2: View Additional Airports Before Flight
This method involves Packing the intended route of flight and then looking at the Airport 3D View for each additional airport just before flying. Doing so causes ForeFlight to store those recently viewed airports in its app cache.
NOTE: While ForeFlight stores the data for up to 20–25 airports in its cache, there is no way to designate “always available” airports in the app memory. Once the cache fills up, the app will delete data starting with the oldest first. ForeFlight recommends using the previous method of Packing a route that includes ALL of the airports for which Airport 3D View is needed.
