I love travelling, but hate the travel &mdash the military-industrial regimen of lining up to check in, lining up to clear security, lining up again to board the flight. And, worst of all, cramming my creaking 6 foot 5 inch frame into a chair meant for pygmies, particularly such pygmies as do not mind hours of physical intimacy with complete strangers. In an alchemy measured in inches &mdash 1.2 inch extra seat width, 7 inches extra seat pitch, 0.5 inches of plastic partition &mdash a business class ticket transforms my grim apprehension of long-haul flights into pleasurable anticipation of a private little bubble floating 10 km above the earth.
