So... It's advertised that the flight plans can be transferred to Foreflight... But how is it done??
Click the Email link under the route and send it to the device that has ForeFlight installed. Then click the Foreflight link in the email.
In addition to the links in the Nav Log email, you can now also use the AOPA GO Mobile app to send the route to one of the supported EFBs. Open the Flight Planning section of the app, select a saved route, open the Nav Log and you will see a button at the bottom of the screen to send the route to an EFB. The EFB must be installed on the same device as AOPA GO (iOS only).
