Best Airlines for Dhaka to Seoul Flights

There is so much to take into account when planning Dhaka to Seoul flights, and it can get a little exciting as well as overwhelming, especially considering the different airlines and their different layover time and ticket rates that seem to flip-flop every few hours. The airline you choose has more of an impact than just the ticket price, especially when you’re crossing oceans to reach South Korea — whether you’re a Bangladeshi worker traveling to the country, a student going for studies, or a first-timer.

Seoul is one of Asia’s most dynamic cities, drawing hundreds of thousands of visitors from Bangladesh every year. And while the route is well-served, not all carriers are equal. Some have improved transit links, some have better baggage policies, and others simply provide you with better value for money.

Here, we take a look at the key airlines that fly on this route, compare comfort onboard, cities of call, baggage policies, and determine which one is best for you and your travel needs and budget! You’ll also find quick tips on when to book and how to find cheaper fares.

Understanding the Dhaka to Seoul Flight Route

Dhaka’s Hazrat Shahjalal International Airport (DAC) and Seoul’s Incheon International Airport (ICN) are separated by roughly 3,885 km in a straight line but because no airline currently runs a nonstop service, your actual journey will cover more distance depending on the stopover.

Historically, Asiana Airlines and Jin Air ran direct Dhaka–Seoul services, but those routes no longer operate. Today, every flight involves a connection through hub cities across Asia, including Hong Kong, Beijing, Guangzhou, Bangkok, Kuala Lumpur, or Singapore.

Dhaka to Seoul Flight Duration

The total travel time depends heavily on which airline and layover city you choose:

• Via Hong Kong (Cathay Pacific): around 8 hrs 55 mins to 9 hrs 30 mins — the fastest option overall.
• Via Beijing (Air China): around 10 hrs 30 mins.
• Via Bangkok (Thai Airways): roughly 13 hours including layover.
• Via Kuala Lumpur (Malaysia Airlines): typically 15–20 hours.
• Via Singapore (Singapore Airlines): approximately 12–13 hours.

Always check layover time separately — a short connection can mean rushing through a busy airport, while a longer layover (6–8 hours) in a well-connected hub can give you time to rest, eat, or even explore.

Dhaka to Seoul Distance and Geography

The direct aerial distance between Dhaka and Seoul is approximately 3,885 km. However, with stopovers factored in, your journey may cover anywhere from 3,885 to nearly 11,000 km depending on the routing. This is why transit experience and layover airport quality matter just as much as in-flight comfort.

Top Airlines for Dhaka to Seoul Flights

1. Cathay Pacific — Best for Speed and Onboard Quality

For the quickest flight to Dhaka from Seoul, Cathay Pacific can’t be beat. They pass through one of the world’s most efficient transit hubs, Hong Kong International Airport (HKG), and the total flight time from DAC to ICN takes approximately 8 hrs 55 mins.

Cathay operates on Boeing 777s, Airbus A330s, and A350s — modern, wide-body jets that offer solid legroom, good in-flight entertainment with the latest films and TV box sets, and attentive service. Business and Premium Economy passengers get enhanced meals and more seat privacy.

Schedules currently run Tuesday, Wednesday, Friday, and Sunday, so it’s worth double-checking dates if your travel window is tight. Fares are on the higher end compared to Chinese carriers, but you’re paying for a smoother, quicker journey with less waiting.

• Approx. total travel time: 8 hrs 55 mins – 9 hrs 30 mins

2. Korean Air — South Korea’s Flag Carrier

There is an appealing side to getting on a Korean Air flight and landing in Seoul, where you are already steeped in Korean culture. Korean Air is the national airline of South Korea and has a wide network, offering multiple hubs to connect Dhaka to ICN.

The airline’s Economy Class checked baggage allowance for flights in this region is typically 20 kg per piece, with one bag standard for economy passengers. Business class travelers enjoy up to 64 kg. Korean Air’s cabin is known for clean presentation, and food quality in Economy is a step above many Asian carriers.

If you have a Korean Air SkyPass account, this route can be a solid way to earn miles for future travel.

• Alliance: SkyTeam

3. Air China — Fast Beijing Connection

The flight from Dhaka to Seoul passes through Beijing Capital Airport (PEK) with a total duration of 10 hours 30 minutes on an Air China flight. It is the second fastest and will typically offer competitive pricing as well, particularly if booking 4-6 weeks in advance.

Of course, the Beijing connection is useful for those travellers who have no objections to passing time in Beijing, as there is a large, modern capital airport to station you at, and much to eat and drink during layovers. Air China’s Economy service is functional, with meals served on board, though the entertainment systems on older aircraft can feel dated.

For budget-focused travelers willing to spend a couple of extra hours in transit, this can be one of the best deals on the route.

• Stopover city: Beijing (PEK)
• Approx. total travel time: 10 hrs 30 mins
• Best for: Budget travelers who want a fast-ish connection
• Alliance: Star Alliance

4. China Eastern and China Southern — Most Affordable Fares

If the flight price from Dhaka to Seoul is your primary concern, then you are likely to get the cheapest flight tickets from China Eastern and China Southern. According to Google Flights, China Southern offers prices for the return journey beginning at approximately $509 and for a one-way trip at $295 during “shoulder” and “off-peak” traffic seasons.

The China Eastern lines pass through the Shanghai Pudong (PVG), and the China Southern lines pass through the Guangzhou Baiyun (CAN). Both are busy International airports with good transit facilities. Travel times are longer than Cathay Pacific — usually 11–14 hours total — but the savings can be significant, especially for families or budget travelers.

5. Singapore Airlines — Premium Experience

Singapore Airlines is consistently rated among the world’s best carriers, and the Dhaka to Seoul connection via Singapore Changi Airport (SIN) reflects that reputation. Total travel time runs around 12–13 hours, and while it’s not the shortest route, the quality of the transit experience at Changi — with its gardens, lounges, and spotless facilities — makes the layover actually enjoyable.

Economy fares are higher than Chinese carriers, but the onboard food, seat comfort, and entertainment system (KrisWorld) are a cut above. If you can catch a promotional fare, Singapore Airlines offers excellent value for what you get.

Note: Fares for this carrier are typically higher during Korean holidays. Understanding why cheap flights aren’t always the best choice can help you weigh cost against comfort on longer routes like this one.

• Stopover city: Singapore (SIN)
• Approx. total travel time: 12–13 hours
• Best for: Travelers prioritizing onboard quality and a world-class transit airport
• Alliance: Star Alliance

6. Thai Airways — Cultural Comfort on a Budget

Thai Airways operates a flight from Dhaka to Seoul with an intermediate stop at Bangkok’s Suvarnabhumi airport, which takes about 13 hours. The airline has a good reputation for providing in-flight entertainment, a Thai style of hospitality, and meals.

What makes Thai Airways interesting is its sub-class structure — within Economy, different fare types give you varying seat selection and flexibility options. If you’re traveling during shoulder season (late January to March, or October to November), you may find good promotional fares.

Suvarnabhumi is a busy airport but well-organized, with plenty of food options and comfortable seating in the transit areas. A long layover here is far from unpleasant.

• Stopover city: Bangkok (BKK)
• Approx. total travel time: ~13 hours
• Best for: Travelers who appreciate service quality at moderate prices
• Alliance: Star Alliance

7. Biman Bangladesh Airlines — Fly from Home

Biman’s checked baggage policy is that Economy passengers have 20 kg (up to 2 pieces), and Business class has 30 kg. Carry-on is 7 kg for Economy and 10 kg for Business. The first-class menu on the aircraft is a reflection of the local food of Bangladesh and is a comfort food for long flights.

Although Biman does not necessarily have the latest engines on all its lines, it is a sure bet for passengers who prefer familiarity and the use of the Bengali language. Reservations are necessary; its flights to Seoul are often booked up during Eid and public holidays.

• Checked baggage: 20 kg Economy (2 pieces), 30 kg Business
• Carry-on: 7 kg Economy, 10 kg Business
• Best for: Bangladeshi nationals and families who value cultural familiarity

Dhaka to Seoul Flight Schedule and Booking Tips

Best Time to Book

Booking 4–6 weeks before your departure date generally yields the best prices. If you’re flexible on dates, use Google Flights’ calendar view to spot the cheapest day to fly in any given month.

Weekday departures (Tuesday, Wednesday) tend to be cheaper than weekend flights. Early morning and late-night departures are often priced lower too, even if they’re less convenient.

Airport Transfer at Seoul Incheon (ICN)

Incheon International Airport is located about 50 km from central Seoul. From there, you can reach the city center by:

• AREX (Airport Railroad Express): About 43 minutes to Seoul Station, roughly KRW 9,500
• Airport limousine bus: 60–90 minutes depending on your destination, around KRW 17,000
• Taxi: Around 60–90 minutes and significantly more expensive, but convenient for groups

ICN is consistently ranked among the world’s top airports and is well-signed in English. Even if you’re arriving late at night, the transit experience is smooth and safe.

Baggage Tips

Before booking, always confirm the baggage allowance for your specific fare class, not just the airline. Some budget fare classes (especially “Saver” or “Light” fares) come with significantly reduced or zero checked baggage. Korean Air, for instance, updated its Economy Saver policy in 2025 to reduce the free checked baggage to one piece for certain routes.

If you’re traveling with a lot of luggage, common for workers or students moving to Korea, it’s sometimes worth paying slightly more for a full-service fare rather than paying per-bag excess fees at the airport.
