Are rising aviation fuel prices changing whether you plan to fly this season?
U.S. aviation fuel prices rose for the fourth consecutive month in October 2026, according to fuel price data collected by iFlightPlanner from 3,367 FBOs and fuel service providers nationwide. Jet A Full Service reached a national average of $8.66, up $0.30 from September, while 100LL Full Service reached $7.85.
Why it matters
Rising aviation fuel costs directly raise operating expenses for pilots, flight schools and aircraft owners who rely on Jet A and 100LL. The steady climb follows a brief dip in June and reflects sustained pressure on fuel supply and pricing across the country.
The October survey of 3,367 U.S. fuel providers recorded a Jet A Full Service average of $8.66, up 3.6% from September and 35.1% since February. The source does not explain what is driving the increases or whether they will continue.

Macro View
The October increases continue an upward pattern documented in iFlightPlanner's national survey series, which recorded the start of a six-month price rise in May 2026. Jet A has climbed 35.1% since February, a pace that places aviation fuel costs well above their early-2026 levels.
Pilots, flight schools and aircraft owners face higher per-gallon costs for Jet A and 100LL, with Full Service prices at $8.66 and $7.85 respectively. Choosing Self Service 100LL at $6.82 can reduce fuel spending by roughly 13% compared with Full Service.
The takeaway
Comparing Full Service and Self Service prices before fueling can meaningfully reduce aviation fuel costs during periods of rising prices.
