Air traffic in Lisbon has grown consistently since ANA Aeroportos de Portugal was privatised four years ago, and last year 50% of Portuguese passengers used the city’s Humberto Delgado Airport. Renato Serra Fonseca chronicles one of Europe’s recent major successes.
LISBON

History
Lisbon Airport had originally been built in the suburb of Alverca do Ribatejo on the banks of the River Tagus. But its location, bounded by the waterway, had limitations, and as traffic began to increase rapidly in the 1930s the government decided to replace it.
Two new facilities were completed towards the end of the decade – the Cabo Ruivo Seaplane Base some 2 miles (3km) east of the city and a landplane airport 4 miles (7km) to the northeast. One of their first major tests was to have been the Portuguese World Expo in 1940, but World War Two brought an abrupt end to the plans.
