Your phone's GPS tracks the flight. Anyone with the link can watch. Works in airplane mode: the path is saved on the phone and uploads as soon as there is any connection.
Your location is only uploaded while sharing, visible to people with your link, and deleted after 7 days. Privacy
Do this before switching to airplane mode, while you still have internet.

Keep it tracking
Keep this page open and the screen on (it asks the phone to stay awake). Plug in if you can.
Airplane mode is fine: GPS keeps working. A window seat gives the best fix.
Uploads resume by themselves on in-flight Wi-Fi or after landing.
