The International Air Transport Association (IATA) reports that premium traffic growth slowed to just 3.8% in September compared to a year earlier.
The increase is down 4.6 percentage points from the 8.4% premium traffic growth in August, according to the industry body. The slowdown is attributed to continuing weak demand in Europe and across the north Atlantic.
Emerging markets, especially those with solid economic growth, drove premium traffic in September, says IATA. Strong markets include those between Africa and the Middle East, which was up 12.4% versus September 2011, and between the Middle East and east Asia, which was up 11%.
IATA says that the world trade, which is a "good proxy for business travel", has slowed in recent months and the outlook for the coming months is "not promising".
