The world’s airports reported continued strong passenger traffic gains in Jul-2011. ACI Director General Angela Gittens said it was "encouraging to see passenger growth continue at a rapid clip, as it has for the past year”. And she remains cautiously optimistic about the outlook for the remainder of 2011, despite a downturn in the freight market and economic concerns in Europe and North America. Worldwide passenger traffic rose 5.0% year-on-year in Jul-2011, following growth of 4.8% in Jun-2011. Growth was propelled by strong international demand across all regions, with the exception of Africa, which felt the impact of civil unrest in several major North African markets.
