BUFFALO, N.Y. (AP) - Delta Airlines says it has pulled a flight attendant from a Buffalo, N.Y.-to-Atlanta flight because a security screener thought he was acting erratically and might not be fit to fly.
    
Delta tells local media in Buffalo that the Transportation Security Administration reported the potential problem after the crew was screened before Flight 1266's scheduled departure at 6:15 a.m. Wednesday.
    
The airline didn't detail the actions that worried the screener but said there was no security threat.

Passengers hadn't yet boarded the plane. It left three hours late with a replacement for the attendant.
    
The episode comes just more than a week after a JetBlue Airways captain's frightening behavior on a New York-to-Las Vegas flight forced an emergency landing in Texas.

He has been charged with interfering with a flight crew.
