PHOENIX (AP) US Airways denied Wednesday that crew members used racial slurs against actor Brandon T. Jackson, who was kicked off a flight because of unruly behavior.

The 29-year-old Jackson had been drinking on the New York City-to-Phoenix flight Monday and became upset when flight attendants stopped serving him alcohol.

The "Tropic Thunder" actor sent out 21 tweets about the experience and says a flight attendant "called me the N-word."

Police escorted Jackson out of the terminal at Sky Harbor International Airport. Officers said they determined that no crime had been committed, so they let Jackson go.

"We've spoken with the crew members involved, and they deny any use of the N-word or racist slurs with Mr. Jackson," said US Airways spokesman Andrew Christie, adding that the actor "was disruptive, and our crew made the right decision to stop serving him alcohol."

A call for comment to Creative Artists Agency and ML Management, who represent Jackson, wasn't immediately returned Wednesday.
