Executive Summary
United Airlines had closed the second quarter of 2026 with operating revenue up 16% year over year to $17.7 billion, absorbing an 84% jump in fuel expense while still raising full-year guidance.
The airline is mid-way through the largest widebody intake in its history, with 20 Boeing 787s arriving in 2026 alone, alongside more than 100 new narrowbody jets.
A record 10-city international expansion for 2027 leans on the new Airbus A321XLR to reach secondary European cities no other U.S. carrier serves nonstop.
Chicago O’Hare and Newark, United’s two largest gateways, both operated under federally mandated flight caps in 2026, a structural constraint that shouldn’t be treated as a mere temporary hiccup.
CEO Scott Kirby’s public pursuit of a merger with American Airlines ended in rejection, leaving organic growth and the JetBlue “Blue Sky” tie-up as United’s main paths to added scale.

Official Sources & Data
United Airlines’ first half of 2026 highlighted two key things.
Premium demand, international expansion and a loyal customer base can offset a fuel shock large enough to erase half a billion dollars in a single quarter. At the same time, the airline’s two home hubs, O’Hare and Newark, ran into hard capacity ceilings set by federal regulators rather than by United’s own ambitions.
Those two forces, pricing power on one side and infrastructure limits on the other, will define how United enters 2027.
Let’s analyze everything in detail.

United operates the largest mainline fleet of any airline in the world, a distinction built through the “United Next” retrofit and growth program launched during the pandemic.
Unlike most of its U.S. peers, United kept its widebody fleet largely intact through 2020 and 2021, a decision that let it move faster than rivals once international travel came back.
United Airlines Revenue & Financial Analysis
Second-Quarter and First-Half 2026 Results
Total operating revenue reached $17.7 billion, a 16 percent increase year over year, with total revenue per available seat mile (TRASM) up 12.1 percent, the strongest unit-revenue growth United has posted since early 2023.
Diluted earnings per share landed at $2.46, with adjusted diluted EPS of $1.99, beating the consensus analyst estimate and landing near the top end of the airline’s own guidance range.
Pre-tax earnings were $1.0 billion, a 5.8 percent margin, while adjusted pre-tax earnings came to $843 million, a 4.8 percent adjusted margin.
Q2 2026 REVENUE BY SEGMENT (YEAR OVER YEAR)
Domestic passenger revenue: +20.3%
Premium cabin revenue: +16.4%
Basic Economy revenue: +11%
Loyalty revenue: +11%
Cargo revenue: +23%
Contracted business revenue: +27%
The cost side moved just as fast.
Fuel expense jumped 84 percent, an $2.3 billion increase driven by a Middle East-linked spike in crude oil that began earlier in the year.
United recovered roughly half of that increase through fares and surcharges in the second quarter and told investors it expects to recover 80 to 90 percent of the increase in the third quarter and all of it by the fourth quarter.
The first quarter set up this dynamic.
Revenue of $14.6 billion, up 10.6 percent year over year, beat estimates, but a $340 million fuel cost increase tied to the outbreak of conflict in the Middle East forced United to cut its full-year adjusted EPS guidance from $12 to $14 down to $7 to $11 and trim planned capacity for the rest of the year by roughly five points.
Trailing Full-Year Trajectory and Guidance
United closed full-year 2025 with record revenue of $59.1 billion, up 3.5 percent, adjusted net income of $3.5 billion, and adjusted diluted EPS of $10.62.
The airline carried an average of more than 496,000 passengers a day while flying the largest mainline schedule in its history, and closed the year with the lowest cancellation rate per seat among major U.S. network carriers.
That fourth quarter also carried a scar most airlines would rather forget.
A 43-day federal government shutdown in October and November 2025 forced thousands of flight cancellations industry-wide, and United’s decision to issue full refunds to affected customers, even on flights that operated, cost the airline roughly $250 million in pre-tax earnings.
FULL-YEAR ADJUSTED EPS GUIDANCE, 2026
January 2026 guidance: $12.00 – $14.00
Cut after Q1 (fuel shock): $7.00 – $11.00
Raised after Q2: $9.00 – $11.00
Q3 2026 guidance: $2.50 – $3.50
For the third quarter of 2026, United guided to adjusted EPS of $2.50 to $3.50, based on a jet fuel price assumption of roughly $3.69 a gallon.
Since the start of July, fuel price moves alone had already added $1.12 to the low end of that per-share range, a reminder of how quickly assumptions built into airline guidance can shift.
Every one-dollar move in the price of a barrel of jet fuel changes United’s projected annual fuel expense by approximately $116 million.
