The plane was parked in the bay when someone spotted smoke at around 7 am. Jet said it arranged another aircraft to operate its flight to Managalore from Bengaluru due to a "technical snag."
"There were fumes due to heating up of the brakes. As a result, all passengers were deplaned and shifted to another aircraft," the source said.
Due to the incident, the flight was delayed by an hour and 20 minutes, the source said. "Jet Airways flight 9W 713 from Bangalore to Mangalore of December 27 was delayed due to a technical snag, while (the aircraft was) parked at bay," a Jet Airways spokeperson said in a statement.
Another aircraft was arranged and the flight departed with 71 'guests' on board, the statement said.
