How AirAsia described the right hedge — and never used it
Confirmed revenue, not forecast flying — a structural answer to airline fuel hedging's biggest flaw.

Every airline that hedges fuel faces the same structural problem. The hedge is sized against expected consumption — forecast flying, forecast passengers, forecast fuel burn. But demand is not a constant. It collapses in crises, softens in recessions, and shifts with geopolitics. When it does, the hedge remains.
A conventional calendar hedge locks in fuel prices months or years in advance, based on a schedule that may never fully materialise. If flights are cancelled, the airline still owns the hedge. It has protected a cost it will not incur, against revenue it will not receive. In a demand shock, this is not risk management. It is a second loss.
The booking curve hedge is a structural response to this problem. It does not ask how much fuel the airline expects to burn. It asks how many seats have actually been sold. The hedge follows the revenue — not the forecast.
The hedge follows the revenue — not the forecast.
The booking curve hedge is a dynamic hedging architecture in which fuel hedge tranches are added incrementally as seats are sold — not as a fixed block set months in advance. The hedge grows with confirmed passenger revenue, not with the flight schedule.
In practice, it works like this:
T-90 Days: 15% of seats sold. Hedge 15% of expected fuel burn for that flight.
T-60 Days: 40% of seats sold. Add an incremental tranche — hedge now covers 40%.
T-30 Days: 75% of seats sold. Add next tranche. Hedge at 75%.
Departure: 95% of seats sold. Final hedge position: approximately 70–75% of actual fuel burn.
The result is a hedge that mirrors the booking curve itself. As revenue certainty increases, so does fuel cost certainty. The two move together — which is precisely the alignment that conventional hedging fails to achieve.
Each tranche is typically short-dated — weeks or a few months out — which also reduces basis risk. Rather than using crude oil futures as a proxy for jet fuel costs a year from now, the airline can use jet fuel-linked instruments closer to the actual delivery date.
Set against a conventional calendar hedge, the booking curve approach offers three structural advantages. None of them are trivial.
Hedge shrinks with demand. If flights are cancelled, fewer tranches are added. Exposure is contained.
Short-dated tranches. Closer to delivery. Better price discovery.
Can use jet fuel-linked instruments near delivery. Lower basis risk.
Hedge size tracks confirmed revenue. Logical symmetry.
Hedge is fixed. Cancelled flights leave the airline holding protection against costs it will not incur.
Long-dated positions. Months or years out. Higher uncertainty, wider spreads.
Often uses crude oil proxies. Jet fuel spread can diverge significantly.
Hedge size tracks the schedule. Revenue may not follow.
The COVID-19 pandemic made this distinction viscerally clear. Airlines with large conventional hedge books found themselves locked into fuel positions as their fleets were grounded. The hedge, designed to protect them, became a source of additional loss. A booking curve structure would have unwound naturally as bookings collapsed.
No hedging structure is without cost. The booking curve hedge accepts a specific trade-off in exchange for its structural elegance.
These are real costs. The booking curve hedge is not universally superior — it is situationally superior. In a world of stable or falling oil prices and volatile demand, it outperforms. In a world of rapidly rising oil prices and stable demand, a conventional long-dated hedge may do better.
