My favorite instances of transit chatterboxes have occurred in Italy. Pedestrians and those on trains, on their phone and very "vocal" with their hand gestures. It made for amusing people watching.<p>Personally, I don't care either way about voice calls on flights at this point. Aside from when my wife and I are traveling and trying to converse, I am usually fully checked out with my in ear monitors and music/video, so I rarely hear much -- I have to remove the IEM to interact w/ airline staff for things like drinks, food, etc.
