Several airplane companies, including Boeing, have started making test runs on successfully sending e-mail from the air. So far the tests have worked. The next hurdle to cross is what kinds of packages to offer and how much money to invest in the prospect.
In-flight packages proposed by at least ten companies are currently being considered. One company, Inflightonline, has announced it has developed content partners that can help a passenger make various reservations ranging from dinner to limousine service all on-line from the sky.
One of the final obstacles to overcome is the financial feasibility of in-flight e-mail. Not only do airlines not want to throw a lot of money at a project that won't fly, they also want to insure that it is something that makes financial sense for passengers as well as the airline companies.
