Airlines Raise Airfares and Fees Amid Rising Fuel Costs

Airline executives face renewed pressure from U.S. Lawmakers to reduce passenger fares if jet fuel prices decline, following a period of sustained increases in airfare, fuel surcharges, and baggage fees driven by higher crude oil costs since the escalation of tensions in the Middle East began in late February 2024.

The call comes as major U.S. Carriers including Delta Air Lines, United Airlines Holdings, American Airlines Group, Southwest Airlines, Alaska Air Group, and JetBlue Airways have collectively raised ticket prices and added or increased ancillary charges over the past year to offset rising fuel expenses, which represent one of the largest operating costs for airlines.

According to data from the U.S. Energy Information Administration, the average price of jet fuel rose from approximately $2.15 per gallon in January 2024 to over $3.00 per gallon by October 2024, reflecting broader increases in Brent crude oil prices that surpassed $90 per barrel during periods of heightened geopolitical tension following the outbreak of conflict involving Iran-backed groups in late February.

In response, airlines implemented a combination of base fare increases and higher fuel surcharges — fees explicitly tied to jet fuel costs — while also adjusting baggage fees, seat selection charges, and change or cancellation fees to maintain profitability amid volatile energy markets.

Delta Air Lines CEO Ed Bastian acknowledged in a February 2025 earnings call that the carrier had adjusted its pricing strategy to reflect “the persistent elevation in fuel costs,” noting that fuel expenses accounted for nearly 28% of Delta’s total operating expenses in the fourth quarter of 2024, up from 24% a year earlier.

Similarly, United Airlines reported in its first-quarter 2025 financial results that fuel costs increased by 18% year-over-year, prompting the airline to maintain higher fare levels across domestic and international routes despite softer demand in certain leisure travel segments.

American Airlines Group cited fuel volatility as a key factor in its decision to keep base fares elevated through the first half of 2025, even as it introduced limited-time promotional discounts in select markets to stimulate demand.

On April 15, 2025, Representative Peter Welch (D-VT) sent letters to the CEOs of six major U.S. Airlines urging them to pass along any future decreases in jet fuel prices to consumers through lower ticket prices or reduced surcharges, citing concerns that passengers may not benefit from potential cost savings if airlines retain pricing gains achieved during periods of high fuel costs.

Welch’s correspondence emphasized transparency in pricing, asking carriers to disclose how fuel price fluctuations influence fare structures and whether reductions in crude oil costs would trigger proportional decreases in consumer-facing charges.

Industry analysts note that while airlines typically adjust fares in response to fuel cost changes, the relationship is not always immediate or symmetrical due to hedging strategies, competitive pricing dynamics, and the need to recover revenue lost during periods of lower demand.

Many U.S. Carriers employed fuel hedging contracts in 2023 and 2024 that locked in prices below market peaks, providing some insulation from the full impact of rising crude values. However, as those hedges rolled off in early 2025, airlines became more exposed to spot market prices, reinforcing the rationale for sustained fare increases.

Southwest Airlines, which historically maintains a more conservative hedging approach, reported in its March 2025 investor update that unhedged fuel consumption represented approximately 40% of its total usage in the first quarter, making it more sensitive to real-time price fluctuations than some peers.

Despite the pressure from lawmakers, airline representatives have generally declined to commit to automatic fare reductions tied to fuel price drops, instead emphasizing that pricing decisions reflect a range of factors including labor costs, airport fees, aircraft maintenance, and competitive market conditions.

The Airlines for America trade group, which represents major U.S. Carriers, stated in a March 2025 response to congressional inquiries that “airline pricing is determined by market competition, not input costs alone,” and that fares remain below pre-pandemic levels on an inflation-adjusted basis for many routes.

As of mid-April 2025, the U.S. Department of Transportation has not indicated plans to regulate airline fuel surcharges or mandate fare adjustments based on energy costs, though congressional oversight hearings on airline pricing practices are anticipated later in the year.
