There's been a lot of talk recently about allowing people to use their cell phones while on an airplane. Technologies are changing so those cell phones apparently won't interfere with a pilot's ability to fly the plane. Regardless, Delta is saying "no" to in–flight calls.
The airline's CEO says it will not allow cell phone calls or internet based voice communication aboard Delta flights, even if the FAA says it's OK.
Last week, Southwest Airlines' CEO said customers on Southwest don't want phone calls during flights and if customers don't want it than Southwest doesn't want it.
Federal regulators are still deciding if the ban on in–flight phone calls will soon be lifted.
