Lufthansa marked its 100th anniversary this month with a major ceremony in Frankfurt, a new conference and visitor center and a positive message about the future growth of European aviation. Less than a week later, the airline group announced it would remove 20,000 short-haul flights from its summer schedule through October.
Besides Lufthansa, airlines are feeling the pressure from recent global events. The industry is facing a wider problem than just balancing high summer travel demand with rising costs.
As airlines trim schedules and raise baggage fees, the deeper question is harder to avoid: how much unnecessary flying was built into the system in the first place? And amid rising costs, who thinks of sustainability?
Lufthansa’s 100th Birthday Overshadowed By Flight Cuts And Legal Pressure
Lufthansa Group began April with its 100th-anniversary celebrations. A week after marking this milestone in Frankfurt with a new conference and visitor center, the airline group announced on April 21 that it would remove 20,000 short-haul flights from its summer schedule through October.
The company framed the move as an optimization rather than a retreat, since Lufthansa estimates they will save more than 40,000 metric tons of jet fuel.
Two days after this announcement, on April 23, a ruling from the Court of Justice of the European Union (CJEU) added legal pressure to Lufthansa’s already difficult week.
Lufthansa’s appeal was dismissed in this long-running case, upholding an earlier ruling that annulled the European Commission’s approval of Germany’s €6 billion state aid to the airline after the COVID-19 era.
KLM Shows The Pressure Is Spreading Beyond Lufthansa
KLM also announced in an official statement on April 16 that it would operate 80 fewer return flights to and from Amsterdam Schiphol over the coming month. This cancellation affects only 1% of its European flights during that period.
The Dutch carrier said in the official statement that the affected routes were “currently no longer financially viable to operate” due to rising kerosene costs, while stressing that there was no kerosene shortage.
An update to the official statement on April 21 confirmed that flights to and from Dubai would remain canceled through June 14, while Riyadh and Dammam were added to the list of suspended routes.
U.S. Airlines Were Quick To Pass The Higher Fuel Costs To Travelers
The pressure is also visible beyond Europe. American Airlines lowered its 2026 profit forecast due to higher jet fuel prices, which could increase costs by over $4 billion this year.
In its Q1 2026 financial results, published on April 23, the airline now expects its full-year adjusted earnings per share to range from a 40-cent loss to a $1.10 profit, down from its earlier forecast of $1.70 to $2.70 profit.
U.S. airlines are already passing cost pressure directly to travelers. One month after the Strait of Hormuz effectively closed, United became the first U.S. airline to announce on April 3 that baggage fees would increase by $10 for both first and second checked bags and by $50 for the third checked bag.
Since then, American, Delta, Southwest, Alaska, and Hawaiian have all raised checked-bag fees, with the last announced changes taking effect on April 10.
Amid Rising Costs, Who Thinks Of Sustainability?
When fuel prices rise this sharply, sustainability can quickly become the first topic to disappear from conversations. Airlines move into survival mode: cutting weaker routes, consolidating flights, raising fees and protecting margins.
Lufthansa’s official announcement mentions that “Passengers will therefore continue to have access to the global route network, particularly long-haul connections. However, due to the increase in jet fuel prices, this will be achieved significantly more efficiently than before.”
That raises an obvious question: if fewer flights are now considered more efficient, why was the system built ineffectively in the first place? That is why sustainability becomes more complicated than “fly less” or “use cleaner fuel.”
Fuel tankering, where planes carry extra fuel from cheaper origins to avoid buying expensive fuel at their destination, could be one way for airlines to avoid increased costs. While it may make financial sense, it does not make sense from a sustainability perspective.
EUROCONTROL estimated that fuel tankering could save airlines €265 million a year, but would also burn 286,000 additional metric tons of fuel and create 901,000 metric tons of unnecessary CO2 emissions annually in ECAC airspace.
Could Sustainable Aviation Fuel Be The Savior?
International Air Transport Association expects Sustainable Aviation Fuel (SAF) production to reach 2.4 million metric tons in 2026, covering only 0.8% of total jet fuel consumption. At current prices, the SAF premium would add another $4.5 billion to the industry’s annual fuel costs.
In the U.S., SAF production is growing, but it is still far too small to materially change aviation’s dependence on petroleum jet fuel in the near future. American Airlines called its 2.9 million gallons usage in 2024 “an insignificant volume” compared with what it needs to reach its goal of replacing 10% of jet fuel with SAF by 2030.
If airlines can cut thousands of flights and still preserve most of their networks, were all those flights necessary in the first place? And if SAF still covers only a small share of jet fuel demand, how long can aviation keep presenting it as the main answer to a climate problem that is already here?
