Fuel hedging by airlines — how carriers lock in jet fuel prices and what it means for fares
Jet fuel is the single largest cost item for most airlines. The way carriers manage that exposure — through futures, swaps, options, and collars — has made and unmade fortunes, and directly influences the price you pay for a flight.
Why jet fuel volatility matters
Jet kerosene (Jet A-1 in most of the world, Jet A in the US) is a middle-distillate refined product, closely related to diesel but refined to tighter specifications for aviation use. Its price tracks Brent crude with a mark-up reflecting refining costs and the distillate crack spread — see our crack spread glossary entry for the mechanics.
For a major carrier like Delta, United, or Lufthansa, fuel can represent 25–30 % of total operating expenditure. The IATA Jet Fuel Monitor tracks industry-wide fuel costs and efficiency benchmarks. Between 2002 and 2022, the price of jet fuel ranged from under USD 0.20/litre to over USD 1.30/litre — a six-fold swing. An airline that fails to manage this exposure faces quarterly earnings swings that make long-term planning and capital investment nearly impossible.
The IATA June 2024 industry outlook estimated global airline fuel costs at USD 229 billion for 2024 — roughly 25 % of total industry revenues.
Hedging instruments explained
Airlines use several derivative instruments to manage fuel price risk:
| Instrument | How it works | Basis risk | Upside retained? |
|---|---|---|---|
| Crude futures (Brent/WTI) | Buy futures contracts locking in crude price | High (jet ≠ crude) | No — fixed cost |
| Jet fuel swap | Pay fixed price, receive floating market price | Low | No — fixed cost |
| Call option | Pay premium for right to buy at strike price | Low–Medium | Yes — if price falls, don't exercise |
| Collar | Buy call + sell put at lower strike | Low–Medium | Partial — capped at put strike |
| Cap (zero-cost collar) | Structured to have nil net premium | Low–Medium | Partial |
Basis risk is the core challenge with crude futures. Jet fuel can trade at a premium or discount to crude that varies widely — the jet crack spread. In 2022, the jet crack spiked to USD 40–50/bbl above Brent as aviation demand surged post-COVID while refinery configurations were still optimised for pre-pandemic diesel demand. An airline hedged with Brent futures got less protection than expected because the crack widening wasn't covered. IATA's hedging guide addresses this tradeoff in detail.
Most large airlines use S&P Global Platts jet kerosene assessments (APXK for Asia-Pacific, CIF NWE for Europe) or ICE jet fuel swaps for jet-specific hedges that eliminate basis risk. The trade-off is lower liquidity and wider bid-ask spreads compared to Brent futures.
Case studies: winners and losers
Southwest Airlines — the textbook winner turned cautionary tale. Southwest built one of the most celebrated hedging programmes in corporate history during the 2000s oil bull market. At one point over 80 % of its fuel needs were hedged at sub-USD 50/bbl when spot traded above USD 130/bbl — a saving the carrier estimated at USD 3.5 billion over the period. When oil collapsed in 2008–2009, however, Southwest held above-market hedges and lost USD 120 million on mark-to-market positions in 2009. The lesson: perfect hedging protects on the way up and hurts on the way down. Southwest's annual reports document the multi-year programme in detail.
Ryanair — pragmatic low-cost hedging. Ryanair typically hedges 12–18 months forward at 80–90 % of anticipated consumption using a combination of crude swaps and options. CEO Michael O'Leary has been publicly sceptical of complex structures and favours simple fixed-price swaps at competitive strike levels. Ryanair's hedging philosophy is covered in its investor presentations.
AirAsia 2008 — the opposite end. AirAsia entered into aggressive long-dated fuel hedges at elevated 2008 prices just before the financial crisis crushed crude from USD 147/bbl to USD 35/bbl. The resulting mark-to-market losses contributed to a significant financial strain and forced renegotiations with counterparty banks. It remains one of the most cited examples of hedging amplifying rather than reducing risk.
The jet fuel crack spread
The jet fuel crack spread — the premium of jet kerosene over crude — is a separate risk factor airlines must manage beyond crude price. It is driven by:
- Refinery configuration: Most complex refineries optimise yields for diesel and petrol; jet fuel output is a by-product. When jet demand surges and other distillate demand is also strong, the crack widens.
- Seasonal aviation demand: Northern Hemisphere summer travel peaks typically widen jet cracks in Q2–Q3.
- Geopolitical disruption: Loss of Middle Eastern refinery capacity or Russian product exports (as in 2022) tightens distillate supply and widens all distillate cracks including jet.
The US EIA and EC oil bulletins publish weekly jet fuel prices. In 2022 the jet crack averaged USD 35–45/bbl in Europe — roughly three times the 2015–2019 norm — contributing as much to airline cost inflation as the crude price rise itself.

How hedging flows into fares
Airlines pass fuel costs to passengers through two mechanisms: base fare pricing and explicit fuel surcharges. The IATA fuel surcharge framework historically allowed carriers to levy a per-sector charge when jet fuel exceeded threshold prices — a practice now largely abolished in many markets under pressure from competition regulators who noted surcharges often outlasted the fuel spike that triggered them.
When hedging is effective, it smooths the pass-through: a carrier locked in at low rates can hold fares while rivals raise them, capturing market share. When hedging backfires, the carrier faces a cost disadvantage versus unhedged competitors who benefit from falling spot prices. The ultimate beneficiary — or victim — of hedging decisions is the passenger, whose ticket prices reflect not just today's crude, but the airline's forward book established months earlier.

Frequently asked questions
Why do airlines hedge fuel costs?
Jet fuel represents 20–30 % of total operating costs. A sudden 30 % spike in crude can wipe out profitability for unhedged carriers within a quarter. Hedging locks in a known cost, helping airlines price tickets confidently and protect margins.
What instruments do airlines use to hedge fuel?
Mainly crude oil futures (Brent or WTI), jet fuel swaps, call options, and collars. Crude futures are more liquid but introduce basis risk. Jet kerosene swaps eliminate basis risk but have wider bid-ask spreads.
Can hedging backfire?
Yes. When oil prices fall sharply — as in 2014–2016 and 2020 — airlines with high hedge ratios at elevated strike prices are locked into above-market costs while unhedged rivals benefit from cheap spot fuel.
How does airline hedging affect passenger fares?
Effective hedging smooths fuel costs, allowing airlines to price fares consistently. When crude spikes, well-hedged carriers can hold fares while unhedged rivals add surcharges. When crude falls, unhedged airlines can cut fares faster.
What is the jet fuel crack spread?
The difference between jet kerosene price and crude oil. It reflects refinery margins for aviation fuel. In 2022, jet cracks widened to USD 35–50/bbl — roughly three times historical norms — because post-COVID air travel recovery collided with reduced European refinery capacity.
