Korean Air Takes Longest B747 Route Title from Lufthansa

Korean Air Reintroduces Boeing 747-8i on Longest Nonstop Route to Atlanta

Korean Air, the flagship airline of South Korea, has made headlines by reintroducing its iconic Boeing 747-8i fleet on the nonstop route from Seoul to Atlanta. This move not only marks a significant moment for the airline but also establishes the route as the longest flown by a passenger-configured Boeing 747, spanning an impressive 7,172 miles (11,443 km). The airline has officially reclaimed this accolade from German carrier Lufthansa, which previously held the title until April 25, 2025.

The nonstop service connects Seoul-Incheon International Airport (ICN) to Atlanta-Hartsfield International Airport (ATL) and is set to enhance travel options for passengers. With a distance of just 39 miles (62 km) more than Lufthansa’s Frankfurt to Buenos Aires route, Korean Air is redefining long-haul travel.

Flight Details and Capacity Enhancements

The inaugural flight of Korean Air’s Boeing 747-8i, designated as KE35, departed from Incheon Airport at 10:26 AM on April 25, 2025, with an estimated arrival in Atlanta at 10:06 AM local time. The aircraft, registered as HL7637 and approximately 8.9 years old, is replacing the Boeing 777-300ER on this route to accommodate the expected surge in traffic during the peak summer season of 2025.

• Passenger Capacity:
  • The Boeing 747-8i offers a capacity of 368 passengers, a substantial increase of 33% over the 291 passengers accommodated by the 777-300ER.
  • The aircraft features a three-class configuration:
  • First Class: 6 seats
  • Business Class: 48 seats
  • Economy Class: 314 seats
  • The economy class capacity rises from 82% to 87% with this transition.

Frequency and Future Operations

Initially, the direct flights will operate twice weekly until early May 2025, after which service will ramp up to daily flights for the remainder of the summer season. Starting September 1, 2025, the route will revert to the smaller 777-300ER.

• Flight Schedule:
  • Departures from Seoul-Incheon: 09:15 AM, arriving in Atlanta at 10:15 AM the same day.
  • Return from Atlanta: 12:30 PM, landing in Seoul at 4:50 PM the following day.

This strategic scheduling allows for seamless connections to Delta Air Lines’ extensive domestic and international network from Atlanta, the busiest airport in the U.S., which served over 108 million passengers in 2024.

The Competitive Landscape and Future of the Boeing 747-8i

Korean Air, Lufthansa, and Air China are the last remaining operators of the Boeing 747-8i in passenger service, with each airline operating a limited number of aircraft. Following the reintroduction of the Boeing 747-8i to Atlanta, Korean Air is also set to deploy this aircraft on its London-Heathrow route from July 25 to October 24, 2025.

However, the future of the Boeing 747-8i with Korean Air hangs in the balance as more economical aircraft like the Airbus A350 are increasingly favored for international routes.

Conclusion

The reintroduction of the Boeing 747-8i on the Seoul to Atlanta route is a significant development for Korean Air and long-haul travel enthusiasts alike. As travelers anticipate the return of this iconic aircraft, the airline continues to adapt its fleet to meet changing demands in the aviation industry.
