In a company-wide memo sent to 80,000 Delta employees this morning, CEO Richard Anderson put his foot down on the issue of in-flight passenger calls. His definitive statement, "Delta will not allow cellular calls or internet-based voice communications onboard Delta or Delta Connection flights," will apply regardless of updated regulations from the FCC. That agency is considering lifting the ban on in-flight calls come 2014, but the Department of Transportation may follow up with its own ruling to maintain the phone-free environment many of us have come to enjoy at 30,000 feet.

Meanwhile, powerful in-flight internet services, like JetBlue's recently launched Fly-Fi, take communications a step further, enabling VoIP and video chat services with performance that makes using these tools more than a novelty. Delta, for its part, will support non-voice cell services pending FCC and FAA approval: "if the FCC lifts its ban on cellular use in flight, Delta will move quickly to enable customers to use text, email and other silent data transmission services gate to gate."
