5. Strong Fragrances
Go easy on the perfume, cologne or strong-smelling deodorant. Odors are intensified in enclosed places; in cabins where passengers are packed like sardines and air is merely re-circulated, your cabin-mates won’t appreciate you for it. Scent is highly subjective. What smells sweet to someone may be nauseating to another. Worse, it could trigger allergic reactions for people with asthma. Better just skip the fragrance. At best, take a shower, and at the very least, wear freshly washed clothes.
