Korean Air and Asiana Fuel Surcharges Jump 4 Levels to Tier 27 in November: Long-Haul Tops 400,000 KRW, Book by Oct 31 to Save

Korean Air and Asiana Airlines have officially published their international flight fuel surcharges departing South Korea effective for tickets issued starting November 1, 2026. Driven by sustained increases in global jet fuel benchmarks, the applicable baseline has surged by four full tiers from Tier 23 in October to Tier 27 in November. Consequently, one-way surcharges on US East Coast routes will surpass 400,000 KRW for the first time this season, while round-trip travel to Europe and the US West Coast will incur nearly 100,000 KRW in additional surcharges per passenger. Crucially, fuel surcharges are determined strictly by the ticket issuance (payment) date, rather than the date of travel. Passengers planning trips in late 2026 or 2027 can completely avoid the hike by finalizing ticket issuance by October 31. Korean Air Official Announcement

Background on the November Tier 27 Fuel Surcharge Spike

South Korea’s international aviation fuel surcharges are set under a tiered pricing schedule authorized by the Ministry of Land, Infrastructure and Transport (MOLIT), pegged to the preceding month’s average Mean of Platts Singapore (MOPS) kerosene price.

• Tier Movement: Following a jump from Tier 21 in September to Tier 23 in October, the benchmark ascends four additional notches to Tier 27 in November, marking three consecutive months of steep increases.
• Scope and Window: Applies to all Korea-departing international flight segments with tickets issued (payment completed) between November 1, 2026 at 00:00 KST and November 30, 2026 at 23:59 KST.
• Issuance-Date Rule: Regardless of whether your departure is scheduled for Christmas 2026, the Lunar New Year holidays in early 2027, or summer 2027, completing payment and e-ticket issuance on or before October 31, 23:59 KST locks in the October Tier 23 rate.

Korean Air One-Way Surcharges by Distance Band

Korean Air categorizes all international routes departing Korea into nine distance bands based on great-circle statute miles. The table below outlines the October baseline, the November Tier 27 rates, and the net cost increase across each distance category:

Note: All amounts represent one-way travel departing South Korea. Long-haul routes to Europe and the US West Coast (Band 8) jump by 48,100 KRW each way (+96,200 KRW round-trip). For US East Coast journeys (Band 9), the one-way surcharge reaches 408,100 KRW, meaning a round-trip ticket will incur 816,200 KRW purely in fuel surcharges.

Asiana Airlines and Domestic Surcharge Adjustments

Asiana Airlines has adjusted its fuel surcharges in parallel under the same MOLIT Tier 27 guidelines:

• Asiana Airlines International: One-way surcharges range from 62,400 KRW on shortest regional sectors to 351,100 KRW on long-haul routes to the Americas and Europe.
• Domestic Flights: Domestic flight fuel surcharges departing within South Korea (e.g., Gimpo–Jeju, Busan–Jeju) are set at 25,300 KRW one-way (VAT included) for November.

Actionable Ticketing Strategies Before October 31

At midnight on November 1 (00:00 KST), global reservation systems will automatically update their surcharge tables. Travelers should heed the following five practical recommendations:

1. Lock in Future Travel Dates Now: If you are planning trips for December winter breaks, January/February 2027 holidays, or spring 2027 vacations, complete payment and ticket issuance prior to 23:59 KST on October 31. For a family of four flying to North America or Europe, issuing before November 1 yields net cash savings of 360,000 to 384,000 KRW.
2. Issue Mileage Award Tickets Immediately: While award tickets cover the base airfare with accumulated miles, carrier-imposed fuel surcharges and passenger facility charges must be paid in cash. A round-trip award ticket to the US booked in November will require over 800,000 KRW in cash co-payments, severely diminishing the redemption value of your miles. Lock in any held or planned award seats before October 31.
3. No Retroactive Charges: Tickets issued on or before October 31 will not be assessed any supplementary fuel surcharge difference when flown in November or beyond. Conversely, if fuel surcharges drop in future months, no refund is granted automatically on existing tickets.
4. Beware of Date Changes Requiring Reissuance: If a traveler subsequently makes voluntary flight changes that necessitate ticket reissuance (Reissue) in November, the newly elevated November fuel surcharge rates will apply retroactively to the revised itinerary. Always verify your fare conditions and change penalties prior to booking.
5. Infant Exemption: Infants under two years of age who do not occupy an individual seat are 100% exempt from international aviation fuel surcharges.
