Easy fix
Add a feature where the tracker can be disabled for a specific amount of time by the owner. You check in your bag and show that you've disabled it until after the plane lands. End of argument.
The might technically be interference from the CPU clock and the Bluetooth IF tuner stage. If it has a 32Khz clock while it sleeps it wouldn't be any different from everyone's wristwatch. Considering how long a tracker runs on a battery, 400 of them put together doesn't likely amount to much.
The simpler answer is that the trackers are difficult to find before stealing luggage. They'd be even harder to find if they were temporarily sleeping.
