Air France-KLM today warned of a “high level” of geopolitical uncertainty and fuel prices.

However, the European airline giant reported resilient trading for April after posting increased losses of €143 million in the three months to March against €99 million in the same period last year.

Passenger numbers increased by 5.2% in the quarter to almost 21 million with revenue up by 1.9% to €5.7 billion.

“The operating result was notably impacted by currency effects, which had a negative impact of €72 million,” the airline said.

“The global context remains highly uncertain regarding the geopolitical environment in which we operate and regarding the fuel prices.

“The forward bookings indicate a resilient start to the second quarter.

“To improve its competitiveness, the group plans to act on all levels by pursuing and amplifying the initiatives already under way in terms of unit cost reduction.”
