A flight from Los Angeles to Orlando was diverted to Dallas Sunday afternoon due to "a security concern," a Delta Air Lines spokesman said.
Spokesman Morgan Durrant did not give specifics about the nature of the concern on Flight 1061, saying the company would defer to authorities on providing further details. He says passengers exited the Boeing 737-900, which was being examined by authorities.
The flight is expected to land at Orlando International Airport around 10:30 p.m.
Two planes have been evacuated on arrival at Seattle-Tacoma International Airport due to what a spokesman called a "security concern."
Airport spokesman Perry Cooper says a JetBlue flight from Long Beach, California, and a regional SkyWest jet from Phoenix were the planes involved. The flights arrived late Sunday afternoon.
Cooper said that out of an abundance of caution, passengers were bused to their gates from the airport's third runway. He said the matter was under investigation and he did not have further details.
The evacuations come a day after bomb threats targeted two jets bound for Atlanta, prompting F-16 fighter jets to escort the planes. Saturday's threats targeted Southwest Airlines Flight 2492, which arrived at Atlanta from Milwaukee; and Delta Air Lines Flight 1156, which arrived from Portland, Oregon.
It was unclear if any of threats were connected.
