By SCOTT MAYEROWITZNEW YORK (AP) a¿¿ The Federal Communications Commission might be ready to permit cellphone calls in flight. But what about the airlines? Old concerns about electronics being a danger to airplane navigation have been debunked. And airlines could make some extra cash charging passengers to call a loved one from 35,000 feet. But that extra money might not be worth the backlash from fliers who view overly chatty neighbors as another inconvenience to go along with smaller seats and stuffed overhead bins. "Common courtesy goes out the window when people step in that metal tube," says James Patrick II, a frequent flier from Newnan, Ga. "You think the debates and fistfights over reclining the seat back was bad. Wait until guys start slugging it out over someone talking too loud on the phone." That's one of the reasons the country's largest flight attendant union has come out against allowing calls in flight. The FCC is proposing to lift an existing ban, and airlines would have to decide whether to let passengers make calls. The ban would remain in effect during takeoff and landing. Delta Air Lines is the only major airline to explicitly state that voice calls won't be allowed on its flights, even if the FCC allows it. Delta says years of feedback from customers show "the overwhelming sentiment" is to continue prohibiting calls. Other airlines aren't as firm. United Airlines says that if the FCC changes its rules, "we will study it along with feedback from customers and crews." American Airlines has offered a similar approach. So has JetBlue, which says it would "welcome the opportunity to explore" voice calls but "would prioritize making the cabin comfortable and welcoming for all." Confused yet? Well, to complicate matters even more, the airlines actually don't need to wait for the FCC. Yes, the government would need to remove the restriction for you to make normal calls in flight. But there are already plenty of ways to make calls legally over airline Wi-Fi networks, while keeping your phone in "airplane mode." The airlines just choose to block such calls.
