The Asia-Pacific region has overtaken North America as the world's largest air travel market with 647 million passengers in 2009, according to the International Air Transport Association.

By contrast, 638 million people flew on commercial flights in North America last year, IATA announced at an aviation business conference on the eve of the Singapore Airshow featuring the world's leading aviation industry players.

Within Asia, China has eclipsed Japan over the past decade as the region's largest domestic market, with 1,400 aircraft compared with Japan's 540 and 5.7 million weekly seats against 2.6 million in Japan.

The Singapore Airshow is taking place after a harrowing year in the global aviation industry, which lost an estimated €11 billion last year as a result of the financial meltdown that began in the US.

IATA director general Giovanni Bisignani told the conference that the Asia-Pacific market would continue to grow rapidly with an estimated 217 million additional air passengers a year in the region by 2013.

"While we see dynamism and diversity within the region, the aspect of Asia-Pacific that excites me most is its potential," said Mr Bisignani.

"More than a quarter of the 2.2 billion people who flew last year, or 647 million people, flew within Asia-Pacific markets.

"It has eclipsed travel within North America as the traditional leader in traffic numbers."

IATA represents some 230 carriers that account for more than 90 per cent of scheduled air traffic, but does not include many of the budget airlines credited with a boom in short and medium-haul travel in recent years.

Its members in Europe, the Asia-Pacific region, and North America recorded year-on-year declines in passenger demand of five to 5.6 per cent last year, according to an IATA report. But Asian airlines staged a strong recovery in December, when demand grew eight per cent from a year ago, nearly twice the global average, the IATA report said.
