Read MoreHide Full Article

Key Takeaways

  • Rising jet fuel prices are pushing airlines to raise ticket prices and add steep fuel surcharges.
  • Airlines like LUV, DAL, UAL and ALK saw a year-over-year jump in fuel expenses in second-quarter 2026.
  • The increase in expenses on the labor front represents another challenge for airlines.

Airfares are climbing globally as soaring jet fuel prices—backed by geopolitical conflicts and refinery constraints—compel airline companies to raise ticket costs and add steep fuel surcharges. Domestic and international ticket prices have jumped significantly, with fall airfares up year over year. International carriers are also actively raising fuel surcharges for their upcoming bookings. According to a travelpulse article, airfares in the United States rose 23.4% year over year in August 2026.

Let’s delve deeper to see how rising jet fuel prices have weighed on the airline companies.

The ongoing tensions between the United States and Iran have resulted in a sharp rise in oil prices, a key input cost for airlines. The ongoing uncertainty over talks between them has added to the uncertain scenario. Stocks in the Zacks Transportation - Airline industry have been badly hit by this turbulent scenario. This upward movement in oil prices is naturally hurting the bottom line of airlines because fuel expenses represent a key input cost for airlines. Currently, oil prices are hovering around $100 a barrel. Crude prices have moved sharply on headlines tied to the Strait of Hormuz, a critical shipping route. With most U.S. carriers having abandoned fuel hedging strategies, they have been left fully exposed to price spikes due to oil supply disruption.

For example, during second-quarter 2026, Southwest Airlines Co. (LUV - Free Report) witnessed an $889 million increase in fuel expense on a year-over-year basis, and this fuel expense weighed on adjusted earnings per share by $1.17. Total operating expenses increased 16.1% year over year, with aircraft fuel and related taxes surging 67%, representing the largest cost headwind during the quarter. Fuel cost per gallon increased 69% to $3.92.

Alaska Air Group, Inc. (ALK - Free Report) had to bear second-quarter 2026 total operating expenses surging 24% year over year. Aircraft fuel expense increased 86% year over year to $1.31 billion as economic fuel cost rose to $4.43 per gallon from $2.39. The increase added approximately $600 million of fuel expense during the quarter.

United Airlines Holdings, Inc. (UAL - Free Report) witnessed operating expenses rise 19.2% year over year in the second quarter, outpacing revenue growth. Aircraft fuel expense surged 84.1% year over year to $5.11 billion as the average fuel price increased 79.4% to $4.19 per gallon. Fuel consumption rose 2.7%.

Delta Air Lines’ (DAL - Free Report) adjusted operating expenses increased 20% year over year in the second quarter. Adjusted fuel expense jumped 77% year over year to $4.41 billion as the adjusted average fuel price climbed 75% to $3.93 per gallon.

Other Headwinds Bothering the Airline Industry

Apart from fuel price hike concerns, the increase in expenses on the labor front represents another challenge for airlines. For example, at American Airlines, salaries and related costs have increased 8.2% year over year in the first half of 2026. With U.S. airlines grappling with labor shortages, the bargaining power of various labor groups has naturally increased. As a result, we have seen pay-hike deals being inked in the space. This is resulting in a spike in labor costs, limiting bottom-line growth in turn.  

To Conclude

Oil prices could remain volatile as the market weighs supply disruptions against the possibility of softer demand and eventual geopolitical easing. This uncertain backdrop strengthens the case for looking beyond companies whose fortunes depend mainly on the daily movement in crude prices.

Despite headwinds like high inflation, elevated fuel and labor costs, the industry has been benefiting from buoyant air travel demand, both on the domestic and international fronts. Upbeat passenger volumes have always been acting as a tailwind. Higher bookings contribute to the airlines’ top-line performance. Stocks in the Zacks Airline industry have shown resilience, particularly among companies focusing on growth strategies and operational efficiency.
