I'm with Jean. It's a huge problem if you are sensitive. It's always a major source of anxiety for me when getting on a plane--unfortunately, flight attendants are often fond of perfume. It's really hard to relate to people who do not experience this sensitivity, as it is not an allergy in the sense that your throat closes up and you swell, etc., but I have felt as if I'd rather pass out than smell a cologne second longer. It causes burning of the throat and nasal passages, headaches--and makes you wonder what people are putting directly on their skin!
