Air cost drivers
Fuel references and the surcharge mechanics that sit on top of them: a monthly jet fuel history, a live weekly jet fuel reading, and a crude reference carried for direction only. This is an air product: no index decomposition, and no spot anywhere.
Jet fuel
Jet fuel explains the direction of the fuel component of an air rate; it does not price a lane, and it is never subtracted from a published index here because no published air index separates fuel.
US Gulf Coast kerosene-type jet fuel, weekly, FOB, USD/gal
Twelve most recent weekly readings, published by the US Energy Information Administration and refreshed once a day at most. The label above is the label this product uses for the series.
Brent crude, daily, USD/bbl, crude reference — not jet fuel
Brent is a crude reference in dollars per barrel, a different unit from jet fuel in dollars per gallon, so it is never drawn on the same axis. It is carried as context for the direction of the fuel component, not as an input to any rate.

Air surcharge mechanics
Fuel is a weekly pass-through. Carriers reset the fuel surcharge on a weekly or fortnightly cycle against a published fuel reference, so a fuel move reaches an air rate in days rather than at the next contract review. A fixed all-in air rate agreed for twelve months is, in practice, a base rate plus a floating component the carrier revises without reopening the contract.
Security is fixed per kilogram. The security charge does not move with fuel and does not scale with distance: it is a flat per-kg amount applied at origin handling. On short, cheap lanes it is a visible share of the all-in rate; on long-haul it is close to noise. Comparing two carriers on base rate alone therefore flatters whoever loads more into security.
No published air index separates fuel. Every air corridor index in this product is all-in, and no ex-fuel twin is published for any of them. There is no ex-fuel air series to decompose against, so this page does not attempt a fuel share: any such number would be modelled, and it is not published here rather than shown with a false provenance.
