How to explain, to those too timid to have tried it, the joy of buying a preposterously cheap flight to somewhere you have never heard of, then pitching up there on spec? I have bought 0.01p flights myself, to places as diverse as Leipzig and Montpellier, so I know where Tom Chesshyre is coming from. How Low Can You Go?, his wryly readable account of "doing" Eastern Europe by low-cost airline, prepared to go literally anywhere, however unpronounceable, provided only the fare is 0.01p, is a true hymn to the Easyjet age. Some of the places he visits, like Brno in the Czech Republic, sound comically awful, but then doesn't masochism, a gluttony for punishment, lie at the heart of most good travel writing? The book can't replace conventional travel guides: there is not enough detail on individual cities. But it captures something of the zeitgesit of the Europe of the early 21st century. In ten years, we will all be far too eco-conscious to do this sort of thing. So savour the craziness with Chesshyre while it lasts.
