Southwest announced that they have started testing wireless Internet access on their jets with plans to expand the test next month. This will allow flyers to log in on their laptop or smartphone.
Thankfully, there is no move afoot to have cellular technology work on-board which would allow phone conversations from wireless devices. Can you imagine the guy who gets on board, talking too loudly into his device, carrying on that conversation while IN flight? My hypothesis would be that incidents of airline passenger "incidents" would go up exponentially.
Internet access = good; wireless voice calling access = please...don't do it!
