background-geolocation (1).log Dots in the above image are the tracked locations and after some time during the flight the tracking stops

[suhairhassan]

We are utilizing the paid version of the Flutter background, coupled with the Firebase plugin, to capture data. The tracking functions work well for other modes of transportation. Thank you for the package.

What was the altitude of this flight? Small aircraft or commercial jet?

[suhairhassan]

Usual passenger airplane. The flight was Airbus A320neo. Tracking at the usual altitude for flights 30k - 40k feet not possible?

[christocracy]

40k feet not possible?

In my experience, no. It's not possible.

Low altitude flights of small aircraft seem to track fine.
