On redeye international flights with exorbitant WiFi fees I'll admit to scanning for MAC addresses, get the top talkers, then come back later when ones been idle for like 15 minutes, presuming the person is asleep and change my mac to take the address and get online.

I just did it for fun, ok fine.

How do you determine who the top talkers are?

The wi-fi on planes is not encrypted.

Even if it was, you’d still see the top talkers

By setting the WiFi card into monitor mode, and using by e.g. Kismet for data collection.

I did it with tshark but yes this is a pretty easy problem to solve.

I think I even made a script in lua to do it automatically
