South Korea Air Fares Rise as Global Oil Prices Jump
Tensions in the Middle East, triggered by U.S. and Israeli strikes on Iran, have coincided with a spike in global jet-fuel prices and a rapid rise in airline ticket costs. A Yonhap News Agency report summarizing mid-April market moves notes that higher oil prices have been translating into steeper airfares in the United States and elsewhere.
In the United States, major airlines have begun lifting fares on domestic routes. Spirit Airlines’ one-way domestic fare stood at about $193, more than double the level a week earlier. Large carriers are also raising their fares on advance bookings; United and Delta domestic routes posted increases ranging roughly from 15% to 57 over the past week, with the sharpest gains on long-haul itineraries.
A traveler interviewed by The Wall Street Journal described how quickly prices moved after the conflict began. He said a Hawaii-bound ticket bought two days earlier had risen by about $400, highlighting how quickly airfares can jump in times of geopolitical strain.

Analysts note that uncertainty over the Hormuz Strait, a key artery for global oil shipments, is feeding higher fuel costs for airlines. Industry observers say carriers with newer, fuel-efficient fleets may buffer the impact, while operators with older aircraft are more exposed to swings in oil prices.
Prices on Asia-bound routes from Korea have also climbed. From Incheon, the average round-trip fare to Tokyo approaches 600,000 won on weekdays, while round trips to Shanghai run near 400,000 won. Both averages are roughly 20% higher than before the conflict began.

In Korea, aviation fuel surcharges are calculated based on the average price of aviation fuel from the 16th of two months prior to the 15th of the previous month. That pricing structure means the full impact of higher fuel costs is expected to be felt more strongly next month, when surcharges are adjusted accordingly. The Ministry of Land, Infrastructure and Transport has held meetings with airline representatives to mitigate consumer harm.
The flight market has come under pressure on the corporate side as well. Shares of major U.S. airlines moved lower in late March and early April, with declines of about 10% to 20% through the end of last month. Global investment firms have lowered earnings outlooks for carriers in light of the ongoing turmoil and price volatility.
Still, demand for air travel remains resilient in the near term. Jet-set travel and spring break travel in the United States have supported ticket sales, and industry executives expect many flights to sell out toward the end of the month and into early next month despite higher prices. United Airlines CEO Scott Kirby has said that consumers are less sensitive to geopolitical shocks than in the past, noting that while fuel prices drive fare increases, a fall in oil could compress those costs and lower fares accordingly.
