Travelers between Singapore 🇸🇬 and South Korea 🇰🇷 have a lot to celebrate this summer as T’way Air doubles its Singapore–Seoul flights and launches a new direct Singapore–Jeju route. These changes, starting from July and August 2025, bring more choices, better prices, and easier travel for tourists, students, and business visitors. The expansion comes at a time when demand for travel between these two countries is rising, and travelers are looking for affordable, direct flights.
T’way Air, a well-known South Korean low-cost airline, is making a big move by increasing its Singapore–Seoul (Incheon) flights and adding a new Singapore–Jeju service. The airline’s decision to boost its presence in Singapore 🇸🇬 comes as more people want to visit South Korea 🇰🇷 for holidays, work, or to see family and friends. The changes start in July 2025 and will continue through the busy summer and autumn travel seasons.
What’s New for Travelers: More Flights, More Choices
T’way Air’s Singapore–Seoul route now offers daily flights using large Airbus A330-200 and A330-300 planes. From July 23 to August 15, 2025, the airline will run two flights each day between Singapore and Seoul. This means more seats and better flexibility for people who want to travel during the peak summer period. After August 15, the schedule changes a bit: from August 16 to 31, there will be two flights on Thursdays and Sundays, and one flight on the other days. Starting September 1, the route goes back to one daily flight.
The big news is the new Singapore–Jeju route, which starts on August 16, 2025. At first, there will be five flights each week using the Boeing 737 MAX 8, a modern and fuel-efficient plane. From September 2 to October 26, 2025, this route will become a daily service. This is a major step because, until now, only one other airline, Scoot, offered direct flights between Singapore and Jeju. Now, with T’way Air in the market, travelers have more options and can expect better prices.
Flight Schedules and Details
For the Singapore–Jeju route, the flight numbers are TW166 and TW165. TW166 leaves Singapore at 2:15 a.m. and arrives in Jeju at 9:20 a.m. on Mondays, Tuesdays, Wednesdays, Fridays, and Saturdays at first, then daily from September 2. The return flight, TW165, departs Jeju at 7:50 p.m. and lands in Singapore at 12:45 a.m. the next day. Both the Seoul and Jeju flights operate from Terminal 3 at Singapore Changi Airport, making it easy for travelers to connect or transfer between flights.
Promotional Fares and Booking Incentives
To celebrate the new routes and increased flights, T’way Air is offering special fares and discounts. The Singapore–Jeju promotional fare starts at just SGD 195 for travel between August 16 and October 25, 2025. There are also several discount vouchers available until July 31, 2025:
- SGD 15 off for bookings of SGD 150 or more on Singapore–Incheon or Singapore–Jeju routes.
- SGD 40 off for bookings of SGD 400 or more.
- SGD 50 early bird coupon for bookings of SGD 400 or more for travel from September 2025.
- Promo code VACAYKR gives up to 15% off on Incheon or Jeju bookings, with the exact savings depending on the exchange rate.
Some earlier offers, like the SGD 20 welcome voucher for new users and the FESTTRIP promo code for up to 12% off, have already expired as of June 30, 2025. Still, the current deals make it much more affordable for travelers to book their trips, especially if they act quickly.
Why This Matters: Background and Context
T’way Air has been operating since 2010 and is now one of South Korea’s top low-cost carriers. The airline flies to over 60 destinations worldwide, using a modern fleet that includes Boeing 737-800s, 737 MAX 8s, Airbus A330s, and Boeing 777-300ERs. The Singapore–Incheon route first started in May 2022 and has grown steadily, showing strong demand from both Singapore and South Korea.
The new Singapore–Jeju direct flights are especially important. Before T’way Air, only Scoot offered non-stop flights between these two cities. Now, with T’way Air joining the route, travelers have more choices, and prices are likely to become more competitive. This is good news for anyone planning a holiday to Jeju, a popular island known for its natural beauty, beaches, and unique culture.
Practical Implications for Different Groups
For travelers, the biggest benefit is more seats and flexible travel options between Singapore and both Seoul and Jeju. This is especially helpful during busy times like summer and autumn, when flights can sell out quickly. The direct Singapore–Jeju flights mean travelers no longer have to stop in Seoul, saving time and making trips easier for families, students, and tourists.
The competitive fares and promotions also make it more affordable for people to visit South Korea. Early bookers and those who use promotional codes can save a lot of money. For example, a family of four could save up to SGD 200 or more by using the available vouchers and promo codes.
Operating from Terminal 3 at Changi Airport also makes things smoother for travelers. They can easily find their flights, check in, and connect to other services at the airport.

Official Statements and Stakeholders
T’way Air has shared news of its expansion through press releases and updates on its website. The airline is proud to offer more flights and better service to travelers between Singapore and South Korea. Singapore Changi Airport is also playing a key role by hosting the expanded T’way Air operations at Terminal 3.
Scoot, the low-cost carrier owned by Singapore Airlines, is now facing new competition on the Singapore–Jeju route. This is likely to benefit travelers, as airlines often lower prices and improve service when there is more competition.
Tourism boards in both Singapore and South Korea are expected to see a boost in visitor numbers thanks to the increased connectivity. More flights mean more tourists, which helps local businesses, hotels, and attractions.
Expert and Industry Analysis
Aviation experts say that T’way Air’s expansion shows strong demand for travel between Singapore and South Korea, especially to places like Jeju that are popular with tourists. The timing is important, too. Jetstar Asia, another budget airline, recently closed, which means there is less competition on some routes. T’way Air’s entry into the Singapore–Jeju market fills this gap and gives travelers more choices.
Industry watchers believe that more competition will lead to lower fares and better service. This is good news for anyone planning a trip, whether for a holiday, to visit family, or for business.
Future Outlook: What’s Next?
T’way Air’s daily Singapore–Jeju service is set to run through at least October 26, 2025. If demand stays strong, the airline may continue or even expand this service. Promotional campaigns could also be renewed or updated, depending on how many people book flights and how the market responds.
The airline is also looking at further route expansions as it grows its network in Southeast Asia and around the world. This could mean even more options for travelers in the future.
