When flight attendants urged the man, who was carrying a religious book, to take his seat, he ignored them, Brafman said. Two friends, who were seated, tried to tell the attendants that the man couldn't stop until his prayers were over in about 2 minutes, he said.
"He doesn't respond to them, but his friends explain that once you start praying you can't stop," said Brafman, who was seated three rows away.
When the man finally stopped praying, he explained that he couldn't interrupt his religious ritual and wasn't trying to be rude. But the attendants summoned a guard to remove him, said Brafman, a writer who had been visiting New York to talk to publishers.
The plane, Flight 9 to San Francisco, took off without the man. It landed at its destination as scheduled, Brafman said by telephone from his home there.
Robin Urbanski, a spokeswoman for United Airlines, a subsidiary of UAL Corp. with headquarters in Chicago, confirmed the man was taken off the plane and put on another flight Thursday morning.
U rbanksi said flights cannot depart if all passengers are not in their seats, which risks a delay, and it is important that passengers listen to the instructions of the flight crew.
The Port Authority of New York and New Jersey, which runs area airports, and the Transportation Safety Administration, which handles airport security, said Thursday they weren't involved in the incident.
