Jet fuel cost collapse from US-Iran ceasefire deal is a direct bullish catalyst for U.S. airlines — long DAL

Jet fuel is typically 20-30% of airline operating costs. A near-halving of spot jet fuel prices is an immediate, mechanical margin tailwind for carriers. Delta Air Lines (DAL) is the largest U.S. airline by revenue and has significant unhedged fuel exposure, making it a direct beneficiary. This catalyst is already priced into oil markets and should flow into airline equity re-ratings within days to weeks.

If the US-Iran ceasefire collapses within the 60-day negotiation window, oil prices could spike back sharply, reversing the fuel cost tailwind and triggering a rapid airline selloff.
