You find the single flight logs tapping on My.Parrot on the start screen, then choose "My Flights". On the right side is a list of your flight (logs). You can tap on the [^] symbol to download the log (JSON file) by sending it to you with your E-mail client.
If there is a green cloud left of a flight entry, this log is also stored on the Parrot server.
Normally every smartphone has a Flight Mode for travelling with airplane, where you have to switch it on.
If not:: turn OFF WIFI, Bluetooth and 3G/4G.
