A Swiss tech firm OnAir will be setting up service to allow airline passengers to use their cell phones and access the Internet on laptops during flights.

China’s Shenzhen Airlines will set up the service by mid-2009 and hope to have a demo aircraft available for the Beijing Olympics next year.

Shenzhen Airlines President Li Kun said: "We are very proud to be the first airline in China to provide passengers with the ability to communicate during flights."

OnAir has already signed deals with various European and Asian airlines that want to carry the technology, the firm said.

So what are we waiting for?
