My daughter and I are through passport control. We’ll be boarding soon. She’s choosing souvenirs in Duty Free, mementos of England for Russian relatives. I always feel so at home in airport lounges, when you’re neither here nor there, where everyone is stateless. It used to be easy to spot the Russians in the lounge: either under- or overdressed. You’d never notice now, it’s hard to tell whether passengers are going home or departing.
