Singapore Airlines has recently begun rolling out the “interweb” on a limited part of its long haul fleet. Currently a handful of their A380s are equipped with an OnAir satellite based system. Fortunately, voice calls are not enabled so the cabin will not be full of chatter. This includes Skype as well.
Rates for the service are $12 for 10MB of data and $30 for 26MB. For some reason, even first class passengers will be required to pay if they want to surf.
In addition to the A380’s there are a few A340s that serve between Singapore and the USA that also have internet connectivity installed.
Singapore Airlines stated that the product will ultimately be installed on all of their A340-500s, A380s and Boeing 777 aircraft. A formal rollout is planned in the coming weeks.
