You may know the sensation. When you get off a plane in a foreign country,
first of all you notice that the air smells different. It is heavy, humid,
permeated with tropical fragrances; dry and crisp from mountain winds;
moist and salty from a nearby sea, or thick and pungent with fumes from
low-quality petrol. Inside the airport another combination of smells
welcomes you - scents of foreign air fresheners in toilets, linoleums or
paints, perfume with heavier or lighter notes depending on what people
prefer in that country.
