New South Korean Regional Carrier Sum Air to Launch ATR 72-600 Service to Ulleungdo Island in 2027 - Sum Air Receives Government Approval for New Ulleungdo Island Route with ATR 72-600





A new South Korean airline called Sum Air has been given official permission to start flights to Ulleungdo Island using ATR 72-600 aircraft. This development aims to improve air travel options to the island, especially with a new airport scheduled to open there in 2027. Operating under the name that means "Island Air", Sum Air seems to be targeting smaller, less frequented
Word is that Sum Air, the fledgling South Korean regional airline, has cleared a regulatory hurdle for its proposed Ulleungdo Island service. They're planning to deploy the ATR 72-600, a turboprop known for its operational economics – some claim up to 30% savings compared to older regional jets, which might translate to slightly less painful fares for island hoppers. Ulleungdo itself is slated to gain its first proper airfield by 2027, finally easing access to this volcanic island. Flights will supposedly originate from Pohang, which isn't exactly a global hub, but strategically placed. Beyond just another route, this initiative reflects a broader ambition to stitch together South Korea's regions, aiming at destinations that have been historically less accessible by air. Whether this new service will genuinely unlock Ulleungdo's potential as more than just a dot on the map – known for its squid and coastal walks – remains to be seen. The airline is still working towards its operating certificate, with first flights optimistically projected for early 2028, pending the airport's completion.

Getting to Ulleungdo Island from Seoul is about to get drastically faster. If you've ever looked at a map of South Korea, Ulleungdo might seem like a speck far off the east coast. Currently, anyone wanting to visit this volcanic island has to brace themselves for a lengthy journey, often involving a six-hour ferry trip. But that’s supposedly changing. Come 2027, a new airline called Sum Air is expected to begin flying ATR 72-600s to Ulleungdo. The promise is a mere 45-minute flight from Seoul. This would certainly open up the island to more visitors, especially those less keen on sea travel. Ulleungdo is known for its rugged landscapes and coastal scenery, often touted as a less explored destination within South Korea. The idea of cutting travel time this significantly suggests a real shift in accessibility. It will be interesting to see if this new air link genuinely transforms Ulleungdo from a remote outpost into a more mainstream travel spot, and whether the fares will reflect the ‘cheap flights’ aspiration often mentioned. The current cost to reach the island by other means is supposedly around 83,000 KRW on average, so the pricing strategy for this new air service will be key to its broader appeal. Whether this will truly unlock Ulleungdo's potential or just add another option remains to be seen as 2027 approaches.

The ATR 72-600 is being touted as the ideal plane for getting around South Korea's islands, especially now that Sum Air is planning to use it to fly to Ulleungdo Island. This aircraft isn't some fancy jet; it’s a turboprop, which from an airline perspective means it’s relatively cheap to run and burns less fuel. For passengers, this could, in theory, translate to fares that are slightly less outrageous when trying to reach places like Ulleungdo.

What’s key about the ATR 72-600 for island runs is its ability to land on shorter airstrips. Forget massive international airports; these planes are built for smaller, regional fields, which is precisely what you find on many islands, or will find, as Ulleungdo is getting its airport ready. This isn’t just about Ulleungdo though. If this model works, it could open up more routes to other less accessible spots around South Korea.

While no one is claiming luxury, these planes do offer a reasonably sized cabin. So, the journey to Ulleungdo should at least be comfortable enough, even if it's not going to be a long-haul experience. Ultimately, the ATR 72-600 seems like a practical choice for Sum Air and for connecting these island destinations. Whether it actually makes island hopping affordable and convenient for the average traveler, and not just slightly less inconvenient, remains to be seen when Sum Air takes to the skies in a couple of years.
What exactly makes the ATR 72-600 the supposed champion for island routes like this Ulleungdo hop? Examining the specs, the aircraft’s touted fuel efficiency is certainly appealing for shorter hauls, and the claim of up to 30% lower operating costs than some regional jets raises eyebrows – potentially good news for keeping fares in check, theoretically. Its ability to handle shorter runways is key, especially when you consider the new airfield planned for Ulleungdo is unlikely to be sprawling. Seating around 70-odd passengers seems about right for these routes – enough to make it viable, but not so many that load factors become a constant worry. And while 45 minutes Seoul to Ulleungdo sounds impressive, one must remember the aircraft's cruising speed is not exactly supersonic; it's more about efficient point-to-point regional connections. The real test will be if this technical suitability translates to a truly improved travel experience and if the economics pencil out to offer genuinely accessible fares for travellers venturing beyond the mainland.


New South Korean Regional Carrier Sum Air to Launch ATR 72-600 Service to Ulleungdo Island in 2027 - How to Maximize Korean Air SKYPASS Miles on Sum Air Flights

As Sum Air gears up to start flying to Ulleungdo Island in 2027 using their ATR 72-600 aircraft, those collecting Korean Air SKYPASS miles should pay attention. It's still early days to know precisely how these new flights will interact with the SKYPASS program. Savvy travelers will want to see if there will be ways to earn or spend their miles on these new routes. It is worth keeping an eye out for any announcements of partnerships or special deals that could link Sum Air flights with Korean Air's frequent flyer program, or potentially with other airlines in the SkyTeam alliance. Checking for launch promotions or tie-ins might reveal unexpected avenues to boost your SKYPASS balance while exploring this newly accessible island destination.



New South Korean Regional Carrier Sum Air to Launch ATR 72-600 Service to Ulleungdo Island in 2027 - Why Ulleungdo Island is South Korea's Next Big Travel Destination in 2027





Ulleungdo Island, situated a good distance off South Korea's east coast in the Sea of Japan, is shaping up to be a place travelers might want to have on their radar, especially around 2027. This volcanic island boasts a modest population of just over 10,000 and covers a small area, yet it's attracting attention for its relatively untouched natural beauty. For those who appreciate coastal scenery, hiking, and generally getting away from more developed tourist spots, Ulleungdo has appeal.

Getting there, however, has long been a hurdle. Currently, the main option is a four-hour ferry, and anyone who travels by sea knows these schedules can be unreliable; cancellations are apparently not uncommon. This isolation has likely kept visitor numbers relatively low compared to somewhere like Jeju Island. While Jeju pulls in millions of tourists, Ulleungdo sees only a fraction of that, in the hundreds of thousands annually.

This could be changing though. An airport is slated to open on Ulleungdo soon, and with it comes the promise of quicker access. A new regional airline, Sum Air, is planning to start flights in 2027. The Korea Tourism Organization seems to be aiming high, wanting to increase visitor numbers significantly. Beyond the main island, there are places like Gwaneumdo, accessible by a suspension bridge, offering more to explore. The improved air links should certainly make Ulleungdo more accessible, but whether it transforms the island into a major destination remains to be seen.
Ulleungdo Island is shaping up to be quite interesting in the coming years, particularly around 2027. Beyond just another scenic spot, it's a volcanic landmass, forged by tectonic shifts far below the Sea of Japan – or East Sea, depending on your cartographic preferences. This geological origin is not just academic; it sculpts the terrain, resulting in those dramatic cliffs and unusual rock formations that are now being touted as tourist attractions. For anyone with a geological bent, it’s prime territory.

What’s striking is its relative isolation. Currently, getting there involves a lengthy ferry journey, often a gamble against weather conditions. The planned air service by Sum Air with the ATR 72-600 will change that equation drastically. It's not just about shaving hours off the travel time from Seoul; it’s about fundamentally altering the island's accessibility. One has to wonder about the ecological impact of this increased access. Ulleungdo boasts a unique biodiversity, with endemic species thriving in its humid continental climate. Will a surge in visitor numbers strain this delicate ecosystem, even if visitor numbers are currently lower than places like Jeju? The island's relatively small population and size make it almost a living laboratory for observing the effects of tourism on a contained environment.

Culturally, Ulleungdo has its own distinct flavor. Beyond the ubiquitous Korean BBQ, their culinary claim to fame seems to be squid, prepared in numerous ways – grilled "Ojingeo-gui" being a local specialty. There's even a Squid Festival, which sounds both intriguing and potentially a bit chaotic. Historically, it’s not a recent discovery; mentions in ancient texts trace back centuries, underscoring its long-held, if somewhat remote, position in Korean history.

The broader picture here involves regional air traffic development in South Korea. More routes like this, especially to less mainstream locations, could reshape domestic travel patterns. Whether this drives fares down across the board due to increased competition remains to be observed, but it's a possibility. As Ulleungdo prepares for its airport opening and the arrival of Sum Air, it's not just about tourism figures going up; it's about observing how an isolated volcanic island adapts to becoming more integrated into the mainland and global travel circuits. The real data points will emerge after 2027, revealing whether Ulleungdo’s potential translates into sustainable growth or something less desirable.

Beyond the initial Ulleungdo service, it appears Sum Air is already eyeing routes beyond South Korea’s borders, with Japan being the next target. This suggests a broader ambition than just connecting domestic islands. Expanding into Japan certainly makes geographical sense for a regional carrier in this part of the world. The stated aim is to tap into the regional travel market and build stronger connections between the two countries. Whether these new routes will genuinely open up travel possibilities, or simply add another layer of complexity to the regional airline landscape, remains to be seen. It's also unclear if this expansion will lead to more competitive pricing, or if it's just a matter of adding destinations to a route map. The actual impact on travelers and regional economies will depend on how effectively Sum Air executes these expansion plans.
Building on their upcoming Ulleungdo flights, Sum Air is indicating further route expansion into Japan. This move beyond domestic routes isn't entirely out of character for a regional airline; once initial domestic operations are underway, looking towards nearby international destinations is a fairly standard next phase. Given the proximity, Japan makes geographic sense as a target for routes operated by the ATR 72-600. These aircraft are tailored for shorter sectors, so we are likely looking at services to Japanese destinations within comfortable range of South Korea.

It’s still unclear exactly which Japanese airports are on their radar – will they concentrate on established major hubs, or will they mirror their domestic strategy and target smaller, potentially underserved regional airports? The proposition is that these routes will boost economic activity and provide more options for travelers. Whether this translates to genuinely novel travel possibilities, or just adds further capacity to already well-served routes remains to be seen. If Sum Air can leverage the operational efficiencies of the ATR 72-600 to offer notably competitive fares on these cross-border flights, it could indeed reshape regional travel patterns. However, the actual cities served, the flight schedules offered, and ultimately, the pricing strategy will be the true test of their impact. One wonders if this expansion is a truly 'additional' plan, or perhaps a strategic redirection of resources after establishing the Ulleung
