The Port Authority of New York and New Jersey said in a statement that Blair, 54, was taken into custody when the plane was parked at the gate. Blair and one of the flight attendants were taken to a hospital for evaluation. The FBI is investigating.
A representative for Blair told several media outlets that a medical emergency led to the alleged conduct. A message left with her publicist was not immediately answered, and Delta did not immediately respond to a request for comment.
Blair is known for major roles in films including "Cruel Intentions," "Legally Blonde" and "Hellboy." In recent years she has become a disability rights advocate. She was diagnosed with multiple sclerosis in 2018, and in 2023 she joined President Joe Biden at the White House to celebrate the anniversary of the Americans with Disabilities Act.
