Marq aviator tracking of commercial flight as passenger, experiences

Based on my previous experiences of trying to track flights as a passenger using Garmin GPS watches, even holding my wrist next to the window, I'd say you're not going to have much joy. I don't think there's anything specific to the Aviator model that makes it any different in this context.

YMMV.

It "works", when you sit next to window and holding watches, best taken off from hand, at window...not much fun...
