American Airlines faced a big stink aboard one of its flights – but the airline insisted Monday that claims of a gassy passenger are a bunch of hot air.

The Sunday afternoon flight from Charlotte, NC, landed at Raleigh-Durham International Airport, where airport officials initially said a passenger “passed gas,” WNCN reported.

The station reported Sunday that the passengers were removed after experiencing nausea and headaches from the noxious fumes.

But airline and airport officials blew off reports of severe flatulence Monday, telling The Post that the plane was not evacuated during a “medical call” after a mechanical issue aboard.

“We did have an aircraft from Charlotte to RDU this afternoon, that landed at 2:19 p.m. ET, and arrived the gate at 2:21 p.m. ET, that is currently out of service for an actual mechanical issue – and odor in the cabin. But it is not due to ‘passed gas’ as mentioned,” airline spokesman Ross Feinstein said.

Airport spokesman Andrew Sawyer said the “medical call about persons affected by an odor came in after passengers deplaned normally.”

The airport’s mixed messages prompted several media outlets to report that the plane had been forced to land in Raleigh – though it was the intended destination – and to be evacuated.

But had the incident been prompted by wind breakage, it would not have been the first.

In January 2016, a passenger passed a note to a flight attendant suggesting an announcement inquiring about the health of a fellow traveler, The Telegraph reported.

“I don’t know if you can make an announcement, but if you can you should say that whoever is farting in the area of rows 10 to 12 should definitely see a doctor because they might have ass cancer,” the note said.
