Air travel is starting to decrease at the tail of the summer season. CBS News Travel Editor Peter Greenberg reviews the travel conditions that could cause delays for major airline operators.
"Three of the four major air traffic control centers are below their 85% staffing threshold," Greenberg says. "That means even in the best of weather, they have to slow things down because they literally do not have enough controllers to work the number of flights the airline scheduled."
Greenberg comments on the price trends for international travel bookings as compared to domestic travel prices.
