Feb. 19 (Bloomberg) -- Air France-KLM Group is considering deferring one or two of the Airbus SAS A380 superjumbo jets it has on order as a recession weakens demand for air travel, said Pierre Vellay, the airline’s director of fleet development.

“It’s a very serious crisis,” Vellay told reporters today in Everett, Washington, where he was picking up Boeing Co.’s first 777 freighter model.

Air France-KLM, Europe’s biggest airline, is also deferring two of the five 777 freighters it has on order. The Paris-based company pushed back deliveries of two it had planned to get this year until sometime between 2010 and 2012, “according to the speed of the recovery” of the industry, Vellay said in an interview.
