And smartphones are the most commonly used gadgets.
The Airline Passenger Experience Association (APEX) and the Consumer Electronics Association (CEA) have surveyed American airline passengers to find 69 per cent of them have used personal electronic devices (PED) – such as a smartphone or tablet – during flights.
But while companies like AeroMobile are working to provide airlines with a secure mobile network that enables calls and communications while in the air, airlines still request that devices remain switched off until told otherwise.
That said, 30 per cent of passengers have accidentally left their gadgets off during the journey, and 61 per cent of that number said the device was a smartphone.
Comparatively, 59 per cent of passengers say they always turn their devices completely off when requested, 21 per cent switch devices to 'airplane mode,' and five per cent say they sometimes turn their devices completely off.
Meanwhile, four in ten passengers would like to use their devices during all phases of flight, including take-off and landing.
With 28 per cent, smartphones are the most commonly used devices during flights, followed by laptops on 25 per cent, tablets on 23 per cent, MP3 players on 23 per cent and e-readers on 13 per cent.
Doug Johnson, VP of technology policy at CEA, said: "Airline passengers have come to rely on their smartphones, tablets and e-Readers as essential travel companions. Understanding the attitudes and behaviours of passengers that are using electronic devices while traveling will help the FAA make informed decisions."
