Air Seoul is making a highly anticipated return to the Seoul Incheon-Guam route for the 2025/26 Northern winter season, after a four-year hiatus. The airline will resume this service on October 27, 2025, providing travelers with convenient access to the tropical destination of Guam. This move reflects Air Seoul’s strategy to cater to increasing travel demand during the winter months, offering a mix of leisure and business travelers more options to explore Guam’s beaches and culture.
Initially, the airline will operate one daily flight, but this will increase to three daily flights from November 15 to December 31, 2025, to accommodate the growing demand during the peak holiday season. The flights will be operated using an Airbus A321 aircraft, a comfortable and efficient choice for this route.

Why This Resumption Matters for Passengers
Air Seoul’s latest flight to Guam will relieve long-held demand while also strengthening Air Seoul’s winter scheduled portfolio. The Japanese route adds value to the current winter offering, providing sorely needed access to the icy hot waters surrounding the Japanese archipelago. The area’s stunning coastal panoramas, engaging historical sites, and an extensive range of aqua and land activities offer an enticing proposition to winter sunseeking travelers. The route is being reopened to position Air Seoul as a leader on the winter pause circuit.
Additionally, this new schedule will expand flight frequencies during the holiday season, ensuring that more people can travel with flexibility. With three daily flights available, passengers will have better options to plan their travel, whether it’s for a quick getaway or an extended stay on the island.

Impact of the Resumption on Tourism and Economy
The resumption of this route will boost tourism not only in Guam but also contribute positively to South Korea’s outbound tourism economy. By making travel to Guam more accessible, Air Seoul plays a crucial role in increasing the flow of tourists, which is vital for the island’s tourism and hospitality industry.
Local businesses in Guam, from hotels to restaurants and tour operators, will also benefit from this expansion. The presence of three daily flights will increase the number of tourists visiting Guam, particularly during the winter months, thus stimulating the local economy.
In addition, on the airlines’ side is the opportunity to recover from the deterioration caused by the pandemic as demand for international travel continues to grow, which with the reintroduction of this highly sought after route, is perfect for them. Air Seoul’s decision to capture this demand during the first winter ever for overseas travel is very well timed.
A Promising Future for Air Seoul’s Guam Route
Guam is just the beginning in the incremental expansion of network for Air Seoul. There is a plan in place to capture strategic air travel markets in the Asia-Pacific region and ensure that increased flexibility in air travel and access to emerging and lucrative destinations is readily served to incoming and outgoing passengers.
This route resumption is part of the airline’s broader efforts to cater to passenger demand by expanding seasonal services and offering competitive options for travelers. For those planning a winter escape, this new service offers the perfect combination of convenience, value, and comfort.
