United's record Q3 revenue gain met a $1.85bn fuel bill
United's Q3 revenue rose $2.65bn, while its fuel bill rose $1.85bn. For Q4 it budgets $4.80 a gallon, 45 cents above the Street's $4.35.
United Airlines posted the biggest revenue quarter in its history, but higher fuel took about 70% of the increase.
Fuel is driving the near-term earnings risk. United's Q4 guide assumes $4.80 a gallon, 45 cents above the Street. It also expects revenue growth above 20% and slower growth in unit costs excluding fuel.
United's earnings release, filed with the SEC on 20 October in an 8-K, shows revenue up 17.4%. Revenue rose $2.65bn to $17.9bn.
Fuel took 69.7% of that gain. Aircraft fuel expense rose $1.85bn to $4.84bn.
Volume did not drive the fuel bill. United burned 1,243m gallons, only 0.8% more than a year ago. Extra flying explains almost none of the increase.
Price explains almost all of it. United paid $3.90 a gallon against $2.43, up 60.3%.
Price alone accounts for about $1.83bn of the $1.85bn rise.
Fares rose faster than the costs United controls. Revenue per available seat mile, the airline measure of unit revenue, rose 15.9%, while unit cost excluding fuel rose 7.8%. Capacity grew only 1.3%.
The adjusted pretax margin was still a thin 6.2%. Adjusted earnings per share were $2.54.
Earnings landed within United's guidance despite a 62% rise in fuel expense. The price rise accounted for 60 of those points.
Higher fares cover most of the fuel increase, although not all of it. On the 21 October call, CFO Michael Leskinen said United recaptured 72% of the extra fuel cost through higher ticket prices in Q3.
That figure measures something different from fuel's 69.7% share of the revenue gain. Revenue rose 1.43 times the fuel increase, yet Leskinen said most revenue was already on the books when fuel jumped.
United expects a similar recapture in Q4. Leskinen said that is below the 100% it had planned for because jet fuel spiked late in Q3 and keeps rising.
United still expects to recover the rest with a lag. Chief commercial officer Andrew Nocella said United aims to "recapture 100% of the price of oil in 2027". CEO Scott Kirby said United plans for fuel "to remain elevated for all of 2027" and expects industry capacity to accelerate.
That sets a hard bar for next year. Kirby said United's goal of double-digit pretax margins in 2027 probably needs at least one of three things: fuel falls, industry capacity falls, or airlines keep trading load factor for yield, meaning fewer full seats at higher fares.
Q4 is the nearer test. In its Investor Update, United guides adjusted earnings of $0.50 to $1.50 a share. The $4.80 comes from the Gulf Coast jet forward curve on 16 October.
Against Q3's $3.90, that is 90 cents more a gallon, or about $1.1bn on Q3 gallons. United gives no Q4 volume, so this is arithmetic only.
Analysts assume less fuel cost than United. Consensus carries about $4.35 a gallon, 45 cents below United's figure. United calls that gap worth about $1.00 a share, the width of its guide range.
United's sensitivity is about 2.5 cents a share for each one-cent move in fuel, for the quarter.
The guide is mostly a fuel bet, and United has sized it. At the $1.00 midpoint, earnings would be 61% below Q3's $2.54.
Analysts expect more than United guides. Reuters reports that LSEG analysts average $1.76, so the midpoint is 43% below expectations.
The 16 October curve can fall as fast as it rose. If it falls to the $4.35 analysts assume, United says about a dollar of earnings returns.
United also expects revenue to keep outrunning costs. It expects Q4 unit revenue growth to accelerate from Q3 and unit-cost growth excluding fuel to step down. Total revenue is expected to set another record, growing more than 20%.
Demand is the strong part of the story. Compared with a year earlier, premium revenue rose 17%, Basic Economy 16% and loyalty 17%.
Cargo and contracted business grew fastest. Cargo revenue rose 23% and contracted business revenue 26%. United also carried a record 49.5m customers in the quarter.
United is not alone in the squeeze. Reuters reports that Alaska Air Group guided to a Q4 adjusted loss of $2 to $2.50 a share. Analysts expected a $1.04 loss.
Alaska's margin shows the damage. Its adjusted pretax margin fell to 1.1% in Q3 from 4.6% a year earlier. Delta cut its annual earnings forecast by nearly a quarter earlier this month after projecting a $6bn rise in its fuel bill.
Fuel spending is rising faster than fares across the industry. Reuters cites government data showing US airlines spent $42.9bn on fuel in the first eight months of 2026, up $13.2bn. Labor Department data show US air fares up nearly 23% year on year in the seven months to September. Fuel has risen faster.
Capacity restraint is the industry's other lever. Deutsche Bank warns, in Reuters, that further fare increases could weaken demand and force airlines to slow flight growth. Delta CEO Ed Bastian warned that airlines may need to restrain flight growth next year to sustain higher fares. United's guide points the other way for now, with unit revenue growth set to accelerate.
United is still growing capacity slowly, although close-in cuts raised its costs. Capacity rose 1.3% in Q3, and Leskinen said United incurred "the impact of close in capacity reductions". Neither exhibit gives a Q4 or 2027 capacity figure.
Chicago limits further growth. Nocella said United is capped at 600 daily flights there, likely well into 2028.
The balance sheet gives United time. Available liquidity ended the quarter at $17.7bn. Total debt, finance leases and other financial liabilities were $26.4bn.
Adjusted net debt is 2.4 times trailing EBITDAR. It was $20.5bn, which includes operating leases and pensions and subtracts cash. EBITDAR is earnings before interest, tax, depreciation, amortisation and rent.
United enlarged its revolving credit facility on 16 October. Available liquidity under it rose from $3bn to $5bn. Its stated goal is an investment-grade rating.
United's Q4 report will settle the fuel bet, although its investor page lists no date. Last year's Q4 call was on 21 January.
If fuel stays near $4.80 a gallon, adjusted earnings land near the $1.00 midpoint, 61% below Q3. If it falls to the $4.35 analysts assume, United's own sensitivity implies earnings near $2.00, by simple addition. The same report will show whether United flew fewer seats than the market expects in 2027.
