"So why hasn't the FAA required children under two to travel in restraint devices? The answer is it has to do with cost—the cost you would have to pay the airline for a seat to contain that device.
In August 2005, the FAA issued a public statement on why it would not mandate safety seats: "Analyses showed that, if forced to purchase an extra airline ticket, families might choose to drive, a statistically more dangerous way to travel. The risk for fatalities and injuries to families is significantly greater on the roads than in airplanes, according to the FAA. [In 2004] nearly 43,000 people died on America's highways as compared to 13 on commercial flights. 'Statistics show that families are safer traveling in the sky than on the road,' said FAA Administrator Marion Blakey."
