Virgin Atlantic passengers will be able to call and text while in the air.
The service, which will allow passengers to make and receive phone calls, and send and receive text messages while in the air, will be available initially on Virgin’s new Airbus A330 flying from London to New York.
Virgin’s Boeing 747 planes, which are currently going through a £50 million refurbishment, will also have the feature. By the end of 2012, nearly 20 aircraft will provide the service.
The A330 is undergoing a £100 million investment by Virgin, including a redesigned upper class (first class) cabin.
The new mobile phone system will be available throughout the aircraft in all cabins and is targeted at business travellers. The service is not permitted during take-off or landing, and American laws mean that it has to be turned off around 250 miles from US airspace.
Virgin Atlantic's chief operating officer Steve Griffiths said: "We have listened to what customers want and connectivity in the air is always on the wish list."
