Mary Kirby, a senior editor at Flight International, is about to publish a story in Airline Business about the breakthrough that is occurring among the airlines that are adding in-flight communications - a long awaited breakthrough after the collapse of Boeing's Connexion.

There are two main approaches - satellite and cell technologies. Those airlines that announced their choices are off to a start. But two huge airlines are keenly being watched - Lufthansa and Southwest. Their approach will likely determine how others react. However, as Mary points out, 2008 looks to become the breakthrough year for in-flight passenger communciations.
