American airline operator Delta Air Lines will not allow passengers to make voice calls on its flights.

The news comes as the US government is leaning towards loosening rules on in-flight mobile use, which could see airlines set up their own policies on mobile use.

CEO of Delta, Richard Anderson, told employees in a memo that the airline will not mobile calls or internet-based voice communication on any Delta flights.

"Our customer research and direct feedback tell us that our frequent flyers believe voice calls in the cabin would be a disruption to the travel experience," Anderson said.

"A "clear majority" of customers in a 2012 survey last year said the ability to make voice calls would make their experience worse, not better."

Recently, the Federal Aviation Administration lifted its ban on using personal electronic devices such as tablets and ereaders below 10,000 feet, saying they don’t interfere with cockpit instruments.
