Singapore Airlines’ first-half net profit fell 43.9% as jet fuel costs surged 90%, outweighing higher revenue from strong passenger and cargo demand.

Singapore Airlines reported a sharp decline in earnings for the first half of its financial year, as a steep rise in jet fuel prices more than offset gains from strong travel and freight demand.

In results released Wednesday, the carrier said net profit for the April-to-September period fell 43.9% from the same period a year earlier, landing at 134 million Singapore dollars (about $104 million). The profit drop came despite solid momentum in passenger traffic and higher revenue, underscoring how quickly fuel inflation can erode margins in the aviation sector.

The airline pointed to a surge in fuel spending as the primary drag on performance. Fuel expenses jumped 90% over the period, a scale of increase large enough to outweigh the benefits from robust passenger activity and cargo operations. Singapore Airlines operates from its main hub at Changi Airport, where it has been managing increased demand as global travel continues to recover, but the cost side of the equation has proved decisive this half-year.

The update highlights the financial pressure airlines face when energy prices rise rapidly. Even with fuller planes and healthy cargo volumes, jet fuel can be one of the industry’s largest and most volatile cost items, leaving airlines exposed when prices spike.

Why it matters

The results show how sensitive airline profitability remains to fuel costs, even during periods of strong demand for flights and cargo. Investors and travelers could see continued focus on cost controls and pricing strategies as airlines try to protect margins. The next key watchpoint will be whether fuel prices ease or remain elevated, shaping the carrier’s earnings outlook in coming quarters.
