American Airlines spokeswoman Andrea Huguely says Flight 3505 carried 47 passengers and three crewmembers. She says the captain reported "smoky haze" in the cockpit.
Sutton says an in-flight emergency was declared, but the smoke dissipated shortly before the plane landed in Killeen. Those on board deplaned as normal.
Huguely says the Embraer 145 has been taken out of service for an inspection.
