GENEVA — IATA has announced global passenger traffic results for September, showing that demand has grown 7% compared to the same month in 2015.

This was the strongest year-over-year increase in seven months, with capacity climbing 6.6% and load factor edging up 0.3 percentage points to 81.1%. Growth in domestic traffic slight outpaced growth in international traffic.

“September’s growth in passenger demand was healthy. Importantly, this rebound from August weakness suggests that travel demand is showing its resilience in the aftermath of terror attacks. We must, of course, be ever-alert to the ongoing terror threat. And overall the industry is still vulnerable to being buffeted by rising geopolitical tensions, protectionist political agendas, and weak economic fundamentals. This will still be a good year for the airline industry’s performance, but our profitability will continue to be hard-won,” said Alexandre de Juniac, IATA’s Director General and CEO.

International RPKs climbed 6.9% with airlines in all regions recording growth compared to 2015. Total capacity climbed 7.2%, causing load factor to slide 0.2 percentage points to 80.4%.

North American airlines experienced a 3.3% rise in demand. While the upward trend in international traffic has eased of late, seasonally-adjusted passenger volumes have risen at an annualized rate of 6% since March. Capacity rose 4.2% and load factor fell 0.7 percentage points to 81.5%.
