As international oil prices continue to rise amid concerns about disruptions in crude oil supply, the fuel surcharge for international flights in October will be applied to the '10th stage', which jumped three levels from September.

Fuel surcharges have risen three levels at a time for two consecutive months, adding to the burden of airline ticket costs for travelers.

In the case of Korean Air, the fuel surcharge for international tickets issued in October is 9,3 to 14,3 won for one-way flights, depending on the distance traveled.

It has risen from 10,3 to 800,22 won this month to more than 6,800 won.

Asiana Airlines will charge a fuel surcharge of KRW 2,800 to KRW 16,3 for one-way flights.

It was also a significant increase from the 800,6 to 3,2 won applied in September.

The fuel surcharge is set by airlines after internal fine-tuning in accordance with the Ministry of Land, Infrastructure, Transport and Tourism's distance proportional system, which has been applied since 17.

When the average value per gallon of Singapore jet fuel is 7 cents or more, it is divided into 100 tiers, and if it is less than that, it will not be charged.

The average price of Singapore's jet fuel from August 9 to September 2, which is the basis for the fuel surcharge for international flights in October, was 3.300 cents per gallon, which is tier 13.

The fuel surcharge for international flights rose to 4 levels in July-August last year, when oil prices soared, reaching a maximum of 600,2016 won.

After that, it was on a downward curve from the third quarter of last year to the first half of this year, and then rose to level 150 in August and 33 in September due to the upward trend in oil prices.

International oil prices have been soaring in recent days due to the extension of oil production cuts by Saudi Arabia and Russia.

On the New York Mercantile Exchange, West Texas Intermediate crude oil recently topped $10 per barrel for the first time in 8 months, and Brent crude futures traded on the London ICE Futures Exchange are also rewriting their all-time highs.
