Following a three year absence, wireless internet service is now returning to air flight service, allowing passenger to surf the web, check their email, and log-on to their corporate network during their flight.  Boeing at one time had a very expensive, multibillion dollar plan to equip planes with a satellite based system, but the idea was shelved. 

However, several small internet companies have now developed less expensive systems that are working well.  Air Tran Airways will install WiFi in 136 of it planes by the end of July.  Delta Airlines and American Airlines, America’s largest airlines, will introduce the new system over the next year.
