Seasonally adjusted demand rose 0.4 per cent month to month in May, the 13th consecutive month of growth.
April saw demand increase 11.3 per cent against pre-Covid crisis levels, with air cargo outperforming global goods for the fifth consecutive month.
North American carriers contributed 4.6 points to the 9.4 per cent growth rate in May, while airlines in all other regions except Latin America also supposed growth.
Capacity is 9.7 per cent below May 2019 levels due to ongoing airline grounding issues. Seasonally adjusted capacity increased 0.8 per cent month-on-month in May, the fourth consecutive month of improvement.
'As economies unlock, we can expect a shift in consumption from goods to services. This could slow growth for cargo in general, but improved competitiveness compared to sea shipping should continue to make air cargo a bright spot for airlines while passenger demand struggles with continued border closures and travel restrictions,' said IATA director general Willie Walsh.
