A Spirit Airlines flight from New York to Fort Lauderdale was diverted to South Carolina because of a noxious smell that at least one passenger likened to “dirty socks.”
The incident happened Thursday evening on Spirit Airlines Flight 779, which departed New York LaGuardia around 8:25 p.m. ET. It diverted to Myrtle Beach around 10 p.m. after several passengers felt ill because of a so-far unidentified mystery smell.
The 228 passengers on the Spirit Airbus A321 deplaned upon arrival in Myrtle Beach and were isolated on the ramp as emergency crews responded, NBC New York reports.
Passenger Steven Costello tells WPLG-TV of Miami that some children on the flight vomited and at least one woman fainted.
“Real bad, we didn’t even know what really happened,” Costello adds to the station.
The smell was severe enough that Myrtle Beach Fire Rescue's Hazmat Team responded to inspect the plane.
Lt. Jonathan Evans, spokesman for Myrtle Beach Fire Rescue, tells WBTW-TV of Myrtle Beach as many as 10 passengers complained of medical issues and that some were treated at a local hospital.
“Officials were linking the medical complaints to that unknown substance that some passengers say smelled like ‘dirty socks.’”
CBS Miami talked to another passenger who described the smell more like smoke.
Whatever the smell, which still has not been determined, emergency crews gave an all-clear after investigating the plane.
“After specific monitoring and hazmat crews entering into the fuselage no substances were found,” Myrtle Beach Fire Department Lt. Christian Sliker said to NBC New York. “The plane is all clear.”
Spirit Airlines acknowledged the incident, telling USA TODAY’s Today in the Sky blog “the source of the odor is being investigated.”
“A handful of guests were checked out by medical professionals and have since been cleared to continue their journey,” the carrier added in a statement.
Spirit sent a replacement plane to complete the journey for Flight 779 passengers. That aircraft departed Myrtle Beach around 3:30 a.m. ET on Friday morning before landing in Fort Lauderdale around 5 a.m. ET.
“We apologize for the inconvenience this diversion has caused,” Spirit said. “At Spirit Airlines the safety of our guests and crew is paramount.”

Pall Corporation has the STC on the A320 series for a system that filters VOCs and almost everything-else out of the bleed air near the source, so that more than just the recirc air is filtered. It basically-eliminates the smelly socks problem. It also solves many other issues relating to stuff in the cabin air environment. Word is that G4 is installing it fleetwide on its A320 series.

On the WCML rail service in the UK, prior the to Pendolino stock being introduced, the old Mk.3 carriage stock had a similar odour when braking. I'm no engineer, but the postings above regarding bleed air would make sense. I used to travel regularly between London & Macclesfield in the 1980s and the first time smelling that was quite alarming to say the least.

It's been a long time since railways used gas turbines for propulsion and I don't think any ever used them for auxiliary power, so there is no chance that any odour encountered as a passenger in a BR Mk. 3 car related to "bleed air". However, those cars were fitted with air-conditioning from new so the closest you'd come would be defects in that system that might have allowed lubricants or refrigerant to enter the conditioned-air circulators.
Similarly, carriages are sometimes fitted with diesel generators to supply lighting, door-operation, and climate-control power where the locomotive cannot and no separate power van is available. This is not the case with Mk. 3s, but I recall a few occasions of exhaust products permeating the saloon when travelling on V/Line's MTH-type carriages where the generators were not part of the original design of the vehicle.
Since you specifically report it occurring during braking though, I'm inclined to say it's nothing more than the brake pads themselves heating as they're applied to the wheel. This is very noticeable when UIC-II LL-type composite brake blocks are used and even more so when they're new, compared to cast-iron types used beforehand. Yet-newer types still exhibit this behaviour, but to a lesser extent.
