Air travel is such a strange experience. It´s such an intimate thing, to travel alongside a stranger for so many hours, to eat together, take in a film, snooze side by side. In economy I think that it´s so intimate, that like neighbours on the same landing, most of us consider that it´s better not to take the risk of ever getting to know them. In business class, there´s just enough room - as elbows don´t actually touch - to take that chance.
