US airlines are rapidly raising ticket prices as jet fuel costs soar 72% in a month, driven by Middle East conflict disrupting oil supplies. Travelers heading to Europe, the Caribbean, Asia, and domestic routes face fares doubling on key paths like New York to London and Los Angeles. Demand stays robust, but experts warn of more pain ahead.

## Why This Matters for 2026 Travel

The Argus US Jet Fuel Index jumped 72% in the past month, outpacing Brent crude's 50% rise to $101 per barrel. Jet fuel ranks as airlines' top expense after labor, hitting US carriers hard since most avoid hedging unlike global peers.

Deutsche Bank analysis of lowest published fares 21 days out reveals sharp week-over-week spikes. This chain reaction stems from Iran effectively shutting key oil corridors, spiking global energy prices.

Cross-country routes saw the steepest climbs, with averages more than doubling. International and leisure paths followed, signaling broad 2026 impacts.

## United Airlines Fare Increases

United Airlines faces transcontinental jumps, like Washington Dulles (IAD) to San Francisco (SFO) at $502, up from $149 a month ago.

On New York (JFK) to London Heathrow (LHR), United's fares hit $846, a 177% weekly surge per Deutsche Bank. New York-London ranks as America's top international route with nearly 4 million seats last year via OAG data.

United CEO Scott Kirby noted last week that higher prices would "probably start quick."

## Delta Air Lines Adjustments

Delta Air Lines' New York to London service climbed from $285 to $553 over the past month.

Transatlantic averages rose 40%, with New York-London more volatile including a prior dip. Delta, as a full-service carrier, may pass costs easier to business travelers.

## American Airlines and Budget Carriers Impacted

American Airlines shares the fare surge alongside peers, though specific routes weren't detailed in recent trackers.

Budget lines struggle more: JetBlue's New York to Santo Domingo (SDQ) hit $566 on March 27, up from $165 – a fourfold yearly rise. Southwest's Baltimore (BWI) to Montego Bay (MBJ), Jamaica, more than doubled weekly; Alaska's Los Angeles (LAX) to San Jose (SJC), Costa Rica, up 40% weekly or 120% yearly.

Spirit Airlines saw broad increases across markets.

## International Airline Responses

Global carriers react too. Air Canada adjusted pricing for higher fuel.

Air France-KLM hiked fuel surcharges from 30 euros to 50 euros ($57) round-trip this week. Air New Zealand cut 1,100 flights, shuttering 4% Friday per [FlightAware](https://[FlightAware](https://flightaware.com).com).

Analyst Michael Linenberg notes worldwide flight reductions underway.
