After a promising start that went through a big hiccup with Connexion, in-flight Internet/connectivity is back. A recent study by In-Stat sees a global market in 2009 of some 800 "enabled" planes rising to 6,250 by 2013. In-Stat's Daryl Schoolar, the analyst who wrote this report, estimates between 20 to 33% of passengers will use this service - a remarkable number. This means he sees revenue of $49m in 2009 growing to $2.2bn by 2013. This revenue growth is sure to make airline manager very happy.
