Air France-KLM unveiled a wider first-quarter operating loss as increased passenger traffic failed to compensate for weak international trade and record fuel costs, reported Reuters.

Operating losses grew to US$785.32 million from $529.98 million a year ago on revenues which grew six percent to $7.42 billion. Net losses were flat at $483.96 million.

The Franco-Dutch group warned of wider operating losses in the first half, but maintained its objectives for the full year as a restructuring plan starts to bear fruit in the second half.

Analysts on average expected a first-quarter operating loss of $736.45 million on sales of $7.27 billion and a net loss of $537.87 million, according to Thomson Reuters I/B/E/S data.
