On December 27, SWA464 was climbing out of KLAS enroute to KPDX when the crew encountered what they called a "flight control anomaly". They asked ATC to stop the climb at 15000 feet while they ran some checklists. They were given delaying vectors while the flight crew sorted things out. After consulting with their company, they ultimately decided to return to KLAS and landed safely a short time later on runway 26L.
