Air France-KLM and Deutsche Lufthansa AG promised a reversal of fortunes for 2025 after a year marked by travel disruptions, delivery delays and weak demand, igniting shares of both airlines as investors look to shake off disappointing returns.

German airline giant Lufthansa said Thursday its 2024 profits dived during a turbulent year marked by strikes, rising costs and delays in aircraft deliveries, but vowed a turnaround plan will boost earnings this year.

Air France-KLM lags behind peers in the lucrative North Atlantic market, allocating just 29% of its long-haul capacity to transatlantic routes compared to Lufthansa and IAG’s 46-47%. Given the strength of this market, Bernstein suggests a higher presence would be more favorable.

Air France-KLM , on the back of promising fourth quarter results, is hoping for even more of a tailwind this year from an unlikely source: American TV shows such as 'Emily in Paris' that have boosted the allure of the French capital.

The airline group said the 39% drop in adjusted earnings for 2024, despite higher revenue, reflected the impact of strikes and a significant increase in costs in Germany.

Deutsche Lufthansa AG expects 2025 earnings to be significantly higher than last year, driven by high demand for travel and an expansion in capacity as new aircraft join its fleet.
