Passengers and crew members on a Thursday afternoon flight to Chicago all got priority privileges to disembark — onto the tarmac — after smoke was reported in plane’s cabin.

Flight 3470 was headed to O’Hare International Airport from Columbus, Ohio when the smoke was reported, according to a spokeswoman for American Airlines.

Emergency crews responded to the plane about 3:50 p.m., but no fire was found, according to the Chicago Fire Department.

Four crew members and 64 passengers were then bused to the terminal, the airline said.

The plane, a CRJ700 series, was towed for further investigation, authorities said. No injuries were reported.
