The world’s airlines lost more than $3 billion in the first quarter of 2009, the International Air Transport Association (IATA) said on Tuesday, maintaining its estimate for full-year losses of $9 billion. In its latest snapshot on the industry, the Geneva-based lobby said weak travel demand and lower freight volumes in the global recession had bled revenues for major carriers, in “a significant deterioration from last year”.

“This deterioration was before the recent rise in fuel prices,” IATA said,warning the 30% increase in oil and jet fuel prices since early May would squeeze airline cash flows further in coming months. Both oil and jet fuel prices have raised almost $20 a barrel in the past two months, and are now 75%higher than their low point at the end of 2008, the Financial Monitor report said.

“Airlines have not yet felt the full impact of this oil price rise,” it said. But it said it was not changing its previous2009 loss forecast of $9 billion, which follows revised 2008 losses of $10.4billion. On Tuesday, US crude traded around $72 per barrel.

IATA, which represents more than 200 airlines,also said carriers trying to fly fewer flights to save costs during thedownturn have not managed to cut capacity in line with shrinking air transportdemand. Leading airlines have been seeking mergers and acquisitions to helpbuild scale and shield them against continued market weakness until the globaleconomy recovers.

Delta Air Lines swallowed rival Northwest Airlines last year to create theworld’s largest airline, and European carriers have also consolidated withDeutsche Lufthansa agreeing to buy Austrian Airlines and Air France-KLMscooping up Alitalia. British Airways is also in merger talks with Iberia, andSingapore Airlines has said it is eyeing acquisitions in China and India.
