Air travel in the United States is expected to more than double in the next 20 years, according to the Federal Aviation Administration's annual forecast released on Tuesday.
It also predicts U.S. airlines will carry 1 billion passengers a year by 2021, a milestone that will come two years earlier than previously thought. (To put that number into perspective, about 712 million passengers flew on domestic carriers in 2010.)
