Despite the rhetoric of globalisation, it is impossible to buy an airline ticket online in the United States with a credit card issued abroad. When I needed a ticket from Boston to Washington last year, and after numerous unsuccessful arguments with airline websites and 1800 numbers, I dropped into the local Harvard travel agency. There was a welcome familiarity in discovering that it was a branch of STA, one of more than 400 branches operated around the world by the Australian-based company.
