Jet A at a Six-Month High: What It Actually Costs

Jet A hit a six-month high in September. The number worth knowing isn’t the monthly move. It’s that full-service Jet A is up 32.7% since January.

Per iFlightPlanner’s monthly survey of 3,370 FBOs and fuel providers, the national average reached $8.36 a gallon, up 4.9% from August. The Eastern region fared worst, at $8.69 and up 7.0% — the largest monthly increase in the Lower 48. For anyone based between Teterboro and Boston, that is your ramp.

What it costs in practice: by our arithmetic, a midsize jet burning roughly 200 gallons an hour pays about $78 more per flight hour than it did in August. At 300 hours a year, that’s $23,000. Measured from January instead, the same airplane is carrying six figures more in annual fuel.

Two caveats worth stating plainly. Full-service retail is the posted price, not what most operators actually pay — contract fuel and volume programs land well below it. And fuel is one line in an operating budget, not the whole thing.

But it moves faster than the others, and it moves first. Maintenance reserves and crew costs are negotiated annually. Fuel reprices every month, and right now it is repricing in one direction.

The reported driver is the continuing war in Iran and the supply constraint that comes with it. That is not something an owner can plan around, which is the point. It belongs in the category of costs you budget conservatively rather than forecast precisely.

For charter buyers, expect fuel surcharges to follow. For owners weighing utilization, this is the kind of input that quietly changes the math on flying versus chartering out. And for anyone building a 2027 operating budget this quarter, a January baseline is now 33% stale.
