Singapore Airlines is investing $50 million to enable in-flight Internet and mobile data services for its customers via a partnership with connectivity provider OnAir. The technology will be progressively rolled out across all of Singapore Airlines' long-haul Airbus A380-800, A340-500 and Boeing 777-300ER aircrafts over the next two years. Following a recent soft launch on a limited number of aircraft, In-Flight Connectivity is today available on 14 aircrafts in the fleet--including all five Airbus A340-500s, which are deployed on the world's longest non-stop flights, between Singapore and both Newark and Los Angeles. Promotional price plans, which will last until Nov. 30, are $25 for 30 MB of data and $10 for 10 MB. A joint promotion with SingTel enables SingTel Mobile subscribers to enjoy discounted roaming rates of up to 40 percent for in-flight text messaging and GPRS data services, as well as up to 20 percent for incoming and outgoing voice calls.
