The Federal Aviation Authority has onpebed an enquiry and promised a full investigation.
Passenger, Jim Bishop, speaking to Fox 2 News Detroit claimed that he had been kept on board for two and a half hours and information was sparse at first.
He said: "It was ten minutes of silence. Nobody said anything. Finally it came over the radio that there had been an accident and we should stay calm. A steward walked past and I asked him - he said he'd been in the job for 35 years and this had never happened before. He didn't know what to do."
As the temperature was below freezing, the Southwest plane was being de-iced when the collision happened.
Southwest Airlines said the damaged plane would now be out of service for maintenance. It had been due to fly to Dallas, the airliner said, and 95 passengers would be moved to other flights.
American Airlines apologised to customers for the inconvenience and said the 150 passengers who were on board - also due to fly to Dallas - were being put on other flights.
