Fuel surcharges go up again on international tickets issued in Korea from October 1.
The level moves from 21 in September to 23 in October, the second rise in a row.
The increase itself is small: on Korean Air, Southeast Asia goes up by roughly KRW 6,000–9,000 one way.
The useful part is that the surcharge is based on when you buy, not when you fly.
If you have not bought tickets for an October or year-end trip yet, ticketing by September 30 keeps September’s rate.
October surcharges (one way from Korea)
| Airline | September (level 21) | October (level 23) |
|---|---|---|
| Korean Air | KRW 48,000 – 354,000 | KRW 49,000 – 362,600 |
| Asiana | — | KRW 53,400 – 301,200 |
Korean Air by distance (as compiled by Air Travel Info, in Korean):
| One-way distance | Example routes | September | October |
|---|---|---|---|
| up to 499 miles | Fukuoka, Qingdao, Dalian | 48,000 | 49,000 |
| 500–999 | Tokyo, Osaka, Sapporo, Shanghai, Taipei | 66,000 | 65,800 |
| 1,000–1,499 | Hong Kong, Guangzhou, Ulaanbaatar | 91,500 | 98,000 |
| 1,500–1,999 | Da Nang, Hanoi, Cebu, Manila | 109,500 | 116,200 |
| 2,000–2,999 | Bangkok, Singapore, Guam, Nha Trang, Phu Quoc | 153,000 | 162,400 |
| 3,000–3,999 | Bali, Jakarta | 156,000 | 168,000 |
| 4,000–4,999 | Honolulu, Dubai, Istanbul | 216,000 | 226,800 |
| 5,000–6,499 | Major European cities, LA, Seattle, Sydney | 325,500 | 322,000 |
| 6,500–9,999 | New York, Chicago, Atlanta, Toronto | 354,000 | 362,600 |
Interestingly, Japan (500–999 miles) and Europe/US West Coast (5,000–6,499 miles) actually go down slightly.
Surcharges are set in US dollars and converted, so some bands can dip.
If you are flying to Japan or Europe, there is no need to rush.
Why it went up
The surcharge is based on the average Singapore jet fuel price from the 16th of two months earlier to the 15th of the previous month.
For October, the August 16 – September 15 average was USD 158.57 a barrel, about 6% higher than a month before.
The industry points to renewed clashes between the US and Iran around the Strait of Hormuz (Newsis, in Korean).
This year so far:
| Month | May | Jun | Jul | Aug | Sep | Oct |
|---|---|---|---|---|---|---|
| Level | 33 | 27 | 19 | 14 | 21 | 23 |
Still well below May’s peak of 33, but noticeably higher than August.
Travel Times calculates that a family of four flying Korean Air to Bangkok pays KRW 252,800 more in surcharges than in August.
When buying before September 30 helps
| Destination (Korean Air) | Extra if bought in October |
|---|---|
| Da Nang, Hanoi, Cebu | KRW 6,700 one way (13,400 return) |
| Bangkok, Singapore, Nha Trang | KRW 9,400 one way (18,800 return) |
| Bali | KRW 12,000 one way (24,000 return) |
| Honolulu | KRW 10,800 one way (21,600 return) |
| New York, Chicago | KRW 8,600 one way (17,200 return) |
For a family of four, even Southeast Asia adds up to KRW 50,000–70,000 return.
If the trip and dates are fixed, ticketing this week saves a little.
Before rushing, check a few things:
- Change and refund rules: on cheap fares, fees can be far bigger than the surcharge difference.
- The base fare: fares move much more than a few thousand won of surcharge.
- The total at checkout: the surcharge is bundled in, so compare final prices.
Low-cost carriers
Low-cost airlines usually change their surcharges monthly in the same way, but the amounts differ.
Check your airline’s notice for October’s figures.
