The two busiest airports in the U.S., Atlanta's Hartsfield-Jackson International and Chicago's O'Hare International, are preparing for the potential effects that sequestration may bring, including possible runway closures. Sean Kennedy of Airlines for America said about sequestration, "Our focus remains in telling Congress, telling the administration that an industry that is moving 2 million passengers a day and 50,000 tons of cargo should not be treated like a political football," Kennedy said. The sequester is scheduled to take effect Friday.
