Korean Air, United Airlines Fuel Surcharges May 2026: Seoul-US Flights Exceed 1 Million Won

Korean Air, Asiana Airlines, United Airlines, and Emirates have issued urgent warnings: round-trip ticket prices from Seoul to the U.S. could exceed 1 million Korean won this May, driven by historic jet fuel surcharges tied to soaring global oil prices. Families are postponing summer vacations, and travel budgets are evaporating as carriers pass unprecedented operational costs directly to passengers.

What Sparked This Move

The culprit is unmistakable: jet fuel. From mid-March to early April, the average jet fuel price hovered around $2.05 per gallon, a sharp climb that has forced airlines to announce record-breaking surcharges on long-haul routes. According to industry analysis, fuel prices must remain above the $2 per gallon mark to trigger these surcharges—and current market conditions show no sign of relief.

Korean Air and Asiana Airlines are leading the charge with the steepest increases. If jet fuel prices stay elevated through May, Korean Air's one-way surcharge from Seoul to the U.S. could surpass 550,000 won, with round-trip fares potentially exceeding 1 million won. This represents a fundamental shift in the cost of transatlantic and transpacific travel, affecting not just South Korean passengers but American travelers departing from hubs like New York, Los Angeles, and Chicago.

Routes and Regions in Focus

The price surge is global in scope. Korean Air, Asiana Airlines, United Airlines, and Emirates have all announced similar surcharges on routes spanning North America, Europe, and Asia-Pacific. The impact is particularly acute for long-haul travelers, where fuel represents a larger percentage of total operating costs.

Route	Airline	One-Way Surcharge	Round-Trip Estimate
Seoul to New York	Korean Air	Up to 550,000 won	Exceeds 1,000,000 won
Seoul to Los Angeles	Asiana Airlines	Up to 520,000 won	Exceeds 950,000 won
US Domestic (Long-haul)	United Airlines	Proportional increase	TBD
Global Routes	Emirates	Indexed to fuel price	Varies by route

The International Air Transport Association (IATA) has documented the correlation between crude oil prices and airline fuel surcharges, confirming that carriers have no discretion once fuel costs breach the $2 per gallon threshold.

What Travelers Get

Korean Air one-way surcharge: Could surpass 550,000 won if fuel prices remain above $2 per gallon through May.
Round-trip Seoul-to-U.S. pricing: Tickets may exceed 1 million Korean won, a historic high for the route.
Fuel price trigger: Surcharges activate and escalate when jet fuel averages above the $2 per gallon mark.
Affected carriers: Korean Air, Asiana Airlines, United Airlines, and Emirates all implementing increases.
Timeline: Surcharges expected to peak in May 2026, with no guaranteed relief date announced.

What This Means for Travelers

Book early if your travel dates are flexible, and monitor fuel price trends through official IATA fuel price data and airline press releases. Consider alternative routing through secondary hubs or exploring domestic alternatives for U.S.-based travelers. If you must travel internationally this summer, lock in fares now—waiting risks exposure to further increases. Bundled packages combining flights with hotel accommodations (offered by Korean Air, Emirates, and others) may provide marginal savings, though the base airfare component will still reflect current surcharges.
