I managed to grab a pair from the local Apple Store last week. Thanks iStockNow! So far I'm really enjoying them (though they are not perfect). I posted a review here:
AirPods, new owner views, problems and questions
The long flight on a 787 is this summer, but we do have a brief flight to LA in two weeks on a 737, so I'll see how that goes. I do get a partial seal in my ears with the AirPods, so there is some external noise reduction. Not like isolating earbuds, but more than zero.
Zero reduction as far as I am concerned, just like the EarPods. You listening in a quiet environment or with the volume turned up?
