As I have two connections international flight. Whether the check luggage goes to the final destination automatically, and how many free check luggages need to advice clearly while booking. Since the two code sharing air flight companies provided different information which was very confusion.

BRING YOUR OWN WATER! They don't serve much for a long flight and I kept having to ask the cabin crew for more.

Your guide to booking flights to South Korea

Get tips on when to book, when to fly and what to know before your trip.
  • If you can plan ahead, the sweet spot for booking your flight is 21 weeks before your trip. KAYAK data shows fares in this window are around 32% lower than last-minute bookings (made within 2 weeks of departure). Not ready to commit? Set a Price Alert and we'll let you know when prices change.
  • If your dates are flexible, January usually has the best deals, while December tends to be the priciest. The best-time-to-travel chart on this page shows how prices move across the year.
  • Wednesday is usually the cheapest day to fly, about 10% cheaper than Saturday, the priciest day. If your dates are flexible, that's an easy way to save. If not, try nearby airports or a layover instead.
  • If arriving on time matters more than price, consider flying with one of the most punctual airlines flying to South Korea: AIR PREMIA, Asiana Airlines, Korean Air, Delta or Alaska Airlines.
  • If you're looking to save, Incheon Intl (ICN) has had the lowest fares over the past 12 months. Just remember to factor in the cost of getting to your final destination.
  • Seoul is the most popular destination in South Korea. Start your trip here and then check out these other places KAYAK travelers love: Busan, Incheon and Jeju City.
  • Consider a layover to South Korea, it can cost less than flying nonstop. Manila Ninoy Aquino Intl (MNL) is typically the cheapest place to connect.
  • When you’re booking your flight to South Korea from the US, there are a few different cities you can fly into. Seoul and Busan are the biggest cities in South Korea, making them popular choices to fly into. Flying into Seoul will give you better access to northern South Korea and Busan will give you better access to southern South Korea.
  • While some hotels in South Korea may accept US Dollars, you can often get a better rate by using the country’s local currency: The South Korean Won. Visa and Mastercard are accepted by most businesses, though it can be handy to have some cash on hand for street vendors and other instances where cards aren’t readily accepted.
  • For travelers looking to visit the border with North Korea, you’ll benefit by flying into Seoul. Most of the international flight traffic from South Korea to the United States comes through Seoul and flying there puts you in close proximity to the DMZ. From Seoul you can take the designated DMZ Peace Train straight to the Demilitarized Zone.
  • If you’re looking to fly into a city where you can have equal access to the rest of South Korea, it can be handy to fly into Daegu. Not only is Daegu a popular destination and a major South Korean city, it is located conveniently towards the center of the country.
  • Jeju Island is one of South Korea’s most popular tourist destinations outside of the major cities, and there are a few different ways to get there. You can take a flight to Jeju from the US, with a likely layover in Taipei or Seoul, or you can fly to Busan and take a ferry the rest of the way.
  • The majority of Americans who visit South Korea choose to fly through John F. Kennedy International Airport (JFK). This airport is well-liked since it serves as a hub for so many reputable airlines that fly internationally from the United States. Due to pricing competition, travelers departing from this airport for South Korea are likely to receive ticket discounts.
  • If your flight from the US is planned to land in South Korea at night and you're taking the Incheon International Airport (ICN) from the JFK route, you might want to think about reserving a hotel next to the ICN Airport. Choosing the Incheon Airport Transit Hotel, located at Terminal 1, is one of the best considerations. This airport provides a complimentary shuttle service to and from ICN Airport.
  • The best option for US parents who want to take their kids on holiday to South Korea is likely to be a flight on Korean Air 86, Asiana 221, or Korean Air 82 through JFK to ICN. Non-stop flights from the USA to South Korea are available year-round from this airport. There is a lower likelihood that your children will be exhausted before landing in South Korea from the USA thanks to the availability of direct flights, which make it possible for travelers to get there in the minimum period of time.
  • The best spot for travelers to unwind while waiting for a flight to their intended destinations is in airport lounges. The majority of low-cost American passengers who want to unwind in an airport lounge on their way to South Korea opt to depart through Salt Lake City International Airport (SLC). Travelers on a tight budget can comfortably relax at Delta Sky Club at the SLC Airport, which provides first-rate amenities at a competitive price.
  • Passengers suffering from mobility challenges need to think about departing from JFK Airport and landing at Jeju International Airport (CJU) when going to South Korea. Visitors with particular requirements and mobility issues can request free aid with their bags, medical support, plus wheelchair transfer from a cab to an aircraft at JFK and CJU Airports.

The crew was great. There was no wifi The cabin temperature got very hot Seat was uncomfortable

The boarding process was efficient and quick. The seats were comfortable. The food was good. The service was excellent. We had a lovely flight from Seattle on Korean air

Flight crew was fantastic. The aircraft was meticulously cleaned at all times. The crew was continuously checking to see if the passengers were ok.

It was good, I liked the self-serve snacks but it was a little difficult to get the alcohol, which is understandable since I wouldn't want kids sneaking it.

Friendly flight attendants and gate agents. Very clean plane and food was good!

I was unable to select decent seats, and so I was stuck in the middle seat because it was selected for me

There was a lot of partial tv shows but not enough to last the flight. The food was incredible! The crew were so helpful and patient. Lots more space than what I usually get on an international flight. Very comfortable!

Stingy on the drinks - 15 hour direct flight and could barely get attention for some water

Not many people, so you can lay down on two seats

The delay in Korea was a pain and set us back a day. I have to give big props to Korean Air for setting up a hotel with dinner and transportation to and from the hotel. I also needed assistance with a wheelchair and they did an outstanding job.

Comfortable seats but I had a hard time with the reclining pull.

Reasonable fair, good service, in sum, I am very happy!

Seating was good in the economy with plenty of leg room. The seat cushions were a little firm though, especially for such a long flight. All meals were Korean as would be expected. The food was typical airline quality. Edible, but not something you would recommend to friends. Inflight entertainment was also all Korean but Korean tv and movies are made well and you can find something to watch. Just be prepared to read subtitles. Overall it was a good flight, especially for the price.

The person in front of me was rude. He may came from some communism countries and don’t care of other people. No common manner and sense between human being.

The staff were very friendly, and the flight was comfortable. That said, there was no option to specify dietary restrictions before the flight, so you may need to bring your own food. Also, there was no wifi available for the flight, though there is an in-flight entertainment console with many Korean-language shows and movies.

The legroom was great for a 5’11” person. The 11 hour direct flight had two meal services included in the ticket price which was less than other airline’s cost without food service (Canada air)from sfo to incheon. The airline is focused towards Korean nationals with the onboard entertainment selection of Korean movies but English subtitles were available. Overall premia air is a great option to fly from the US to Korea.

Plane and service were great. The entertainment is only for Koreans. Wish there were vegetarian options for food. All in all pleasantly surprised. Economy premium was quite good.

Great airline, but there was no English entertainment (movies or shows)

One of our luggage items was damaged during our flight to Newark from Incheon. Although our email communication was not responded to, when discussing the matter with the staff at the Newark checkin before our return flight to Incheon, we were provided with a free replacement luggage item. This customer service was, overall, very satisfactory.

Some favorite food ran out of service and I have to eat what was left available. Also I had to drink cold red wind! Why could not have been kept in room temperature?

Waited a long time at JFK to board with no information being readily available.Left about 45 minutes late and it was 2:45 AM in JFK.Nothing todo. Second deck of the Airbus is more comfortable or seems that way because there is less people. Food was OK. The food on secondleg was better as we had ordered it before hand. We thought we had did that on the long first leg but we were told we did not. Cabin crew was generally nice. There are people who lean back when eating as they wait for food to be delivered and know no one will check -- drag. TV selection was awful movies OK. Comfortable all in all.

Not enough seat cushion. Butt was hurting especially on long flight. Not enough movie selection. Entertainment was outdated. Coffee served was cold. Other than that flight was good.

Humm, I should have known that the seat I peaked on my flight from Inchon to Manila was designed for a toddler or very small person.

The staff hold my luggage to steel and exchange my stub, i was very disappointed.

Kayak along with airfare assay are attempting to steal my money. Charges are being pressed.

Customer service and attention to details. The food was good.

I’d have rated Asiana good except an unfortunate incident in which I felt one of your employee didn’t really help us. During the first leg of the trip, the flight from LAX to ICN, I left my backpack on the plane. When I realized, I reported to one of your employee who promised me that it’d be taken care of, that my backpack will be there at HCM city. When we arrived there, HCM people had no idea and my backpack was still at Incheon airport who denied any knowledge whatsoever. I was left in the cold and felt helpless. I was very disappointed. I’d like someone to look into this and let me know.

It was my first time flying Asiana but i was very pleased with how professional and understanding the flight crew is with little kids. One flight attendant held my 3 year old daughter’s hand guiding her to the exit after landing while i had my hands full with luggage and my infant. She was very helpful.

My luggage didn’t arrive with my flight. Flight was delayed by nearly 2 hours while we sat on the plane and I almost missed my connecting flight and subsequently missed the last train from the airport so it took me another 2 hours to get to my destination after arriving, Crew skipped me several times when offering beverages, and I couldn’t get their attention at times because they wouldn’t even make eye contact with me. They didn’t give me a form for disembarking so I had to go to the back of the line after waiting an eternity for immigration. Paid for on flight wi- fi that didn’t work for most of the flight.

Love flying Asiana. Been using it for over a decade now.

My bag was open when I got to Portland and all my clothes were wet and my parking pass was wet

Had to deplane 2 x due to problems with plane. Delayed over 6 hours ans was given a $12 food credit which barely oaud for anything and limited to wear incoukd redeem.

After boarding the plane had to wait an hour at the for the copilot to show up before we could depart

No beverage/snack service without any explanation or reason. Late boarding and delayed flight.

more room in seats, larger snacks, more comms with delays

There was overbooking that delayed boarding. Then an airport emergency lockdown that caused further delays in boarding. However the time was made up during flight and there was a minimal delay in landing. Everything else was excellent.

I was given middle seat on this flight and prior Boston to Seoul flight That is a problem for long flights, Kayak system did not give me a change to select my seats and assigned me middle seats regardless of my elevated status in Delta. This needs immediate attention.

A 12 hour flight during the day with one real meal service - are you kidding? Also the breakfast was one of the worst and not what was listed

The flight attendant on Korean airline was a super nice. it’s one of the best over-sea airline I flew so far.

All in all it was a long flight in economy class. There’s only so much comfort one can expect on a plane. The seats felt exceptionally hard and as an over 6’ individual I’ll seldom feel great about legroom. The food was good and the flight crew was great. The headphones provided for the movies were terrible, though

Fantastic experience once again flying with United! There was great communication from the cockpit and one of the flight attendants went out of her way to get my two little kids some special treats which elevated our travel experience coming home.

1) United economy seats barely recline. 2) I have yet to get United WiFi to work, after numerous flights.

Flight attendants need to know their plane. Seated in first row yesterday. The seat had about a 1 inch recline that was not adjustable. I don't appreciate being awakened to raise a seat that can't go any further forward and such a small recline is either irrelevant or the plane needs to be repaired. Not the way to treat any customer and especially the ones who have paid that level of money for the seats.

The experience was good overall; however, my United Airlines Mileage Plus Account didn't reflect my flights to Houston from Newark. In essence, my mileage rewards points do not reflect my actual travel. This should be corrected.

Delayed - leaving, delayed getting to the gate at destination. What should have been a very easy flight and experience was not.

Plane arrived an hour before departure. Plane was completely boarded and ready for push back when they decided they needed to change a tire. 1 hour delay on the plane when this could have been done before we got on the plane.

Flights was great, service and transit support was outstanding - but the food was limited and of poor quality - only a snack on the first hour for 2 hours 1/2 leg. and a light breakfast on the second 4 hour leg.

The seats are very small, that is all the staff did a good job.

It was great. The staff is always helpful and polite. The app is great and makes the whole trip and process so easy. They even offer a step to step guide to your correct terminal. And they keep all the information you'll need updated. Anything you can think of! Great experience.

United Airline crews were very friendly and very attentive. 12 hours flight was gone like in a shorter one.
