An American Airlines flight from Washington to Texas landed at Nashville airport, Tennessee, after passengers alerted the crew to the smell of burning sulphur.
Lynne Lowrance, a spokeswoman for Nashville International Airport Authority said all the passengers and their luggage were taken off the plane and searched.
A very unlucky canine team was brought in to sniff the aircraft for explosives.
After questioning by the FBI, a female passenger admitted to lighting matches on board the aircraft to conceal her gas, Ms Lowrance said.
“For a long time she did not admit to striking matches and I think that was just out of embarrassment,” she said.
The unidentified woman was not charged, but “American Airlines did ban her from flying on their airline for a very long time,” Ms Lowrance said.
