Is Airline ETF in a Tough Spot as Fuel Costs Threaten Q3 Profits?

Delta Air Lines (DAL) slashed its 2026 adjusted earnings forecast by nearly 25%, citing a surge in jet fuel prices tied to the Iran war. The carrier expects annual fuel costs to run $6 billion above 2025 levels.

The cut lands despite record revenue and strong travel demand. Demand is not the problem; input costs are. Fuel is absorbing the top-line strength and compressing profitability, and the squeeze extends across the sector rather than sitting with one carrier.

That puts the broader group on notice ahead of Q3 earnings. Other major carriers are set to report, with results expected to be mixed. Interpretation: if DAL, which posted record revenue, still needs a roughly 25% guidance reduction, peers with thinner margin cushions face similar pressure. UAL, AAL, LUV, ALK and JBLU all sit in the reporting window the article flags.

The article also notes airlines may need to restrain capacity growth in 2027 to protect margins. That is a forward-looking read, not guidance from any single carrier, but it signals the industry could trade growth for pricing discipline. For JETS, the airline ETF, the setup carries the same fuel-cost overhang that hit DAL.
