Smedley tweeted earlier today that he would be flying to San Diego, later adding that his flight had been rerouted to Phoenix, seemingly due to concerns about "security and our cargo." Smedley's tweets match the flight pattern of AA Flight 362, shown in the above image from Flight Aware as well as AA's online records.
Update: The FBI has released a statement to Game Informer. It's not much of a statement, but it shows the authorities are at least aware of the situation. "Today AA Flight 362 traveling from Dallas to San Diego was diverted to Phoenix Sky Harbor Airport. The flight landed without incident. Passengers were safely removed from the plane," the Bureau writes. "The investigation is still ongoing."
