Southwest prepared for jet fuel at $3.30 a gallon by passing on cost increases to passengers. Now it is preparing for jet fuel at $3.50 a gallon, CEO Gary Kelly said in an interview. The acquisition of AirTran in 2011, increased the size of Southwest by 20%, and is expected to generate additional revenue synergies of $400 million to $500 million. It also gives Southwest access to Atlanta and increases the number of cities served from 72 to 94. Kelly sees additional opportunities for growth in the lower 48 U.S. states before looking at markets in overseas destinations close to the U.S. Southwest has an order of 100 bigger and more fuel efficient 737-800s from Boeing. Boeing's Max jets are expected to be delivered in 2017. Other opportunities for growth will be expansion from Dallas Love Field to more destinations beginning in 2014.
