alt Hacker News> These incidents are literally called "fume events"
Your first FAA link says that these 'fume events' are rare: "The report found that the rate of cabin air quality events is less than 33 events per million aircraft departures." This is about one event every 30,000 flights.

If you think of the last 10 flights you were on, how many had the gym sock smell? That's the real occurence rate. I'd say in my experience across all airlines its around 7/10 flights I can detect via smell a fume event.

That sounds awful; it means 3+ times a day a whole plane of a passengers is getting sprayed with this stuff.
I have a pretty sensitive sense of smell, and I regularly smell oil/smoke/hydrocarbon smell after they're starting the engines. It also sticks on your clothes after the plane ride, and I'm quite sure it's not just stinky seat smell.
