South Korea has restricted the entry of all travelers who have been in the Hubei Province of China in the past 14 days. Chinese nationals with passports issued in the Hubei Province are also not allowed to enter the country. Korean visas issued by the Wuhan Consulate in the Hubei Province are invalidated. Nationals of China and travelers arriving from China must have visas to transit through South Korea.
Travelers arriving from China with a diplomatic, consular, official, service or special passport or who are nationals of Albania, Andorra, Barbados, Dominica, Guyana, Ireland, South Korea, Malta, Mexico, Monaco, Nicaragua, Palau, San Marino, Slovenia, St. Kitts and Nevis, St. Vincent and the Grenadines, the United States, the United Kingdom, the Vatican City and Venezuela may still transit through South Korea without a visa.
Short-term visas (type C-1 and C-3) issued on or before April 5 are invalidated. Visa exemptions for 90 nationalities with normal passport are temporarily suspended, except for airline crew.or passengers with an APEC Business Travel Card. Travelers with a visa on an expired passport must present a printed "Visa Grant Notice" and the expired passport to the immigration upon arrival.
Foreign nationals residing in South Korea on most types of long-term visa will need to apply for a re-entry permit at a local immigration office or at the airport before undertaking any travel out of South Korea. Those traveling with a re-entry permit will also be required to have a medical examination no earlier than 48 hours before they plan to return to South Korea, and to obtain a medical certificate in English or Korean demonstrating COVID-19 negative status. Merchant seamen with a visa must have a medical certificate with a negative COVID-19 PCR test result issued at most 48 hours before departure. The certificate must be in English and the passengers must have two copies of the certificate. All flights must arrive at Incheon International Airport (ICN) between 5:00 am and 8:00 pm.
All travelers arriving in South Korea will be subject to PCR testing and a mandatory self-quarantine for 14 days. In some cases, Korean authorities have permitted immediate blood relatives or spouses of long-term residents to self-quarantine at their family’s home. For this, travelers would need to provide proof of relationship (e.g., marriage or birth certificate), and should understand that Korean immigration officials have the final authority to approve quarantine arrangements. All travelers including airline crew members must also complete Health Declaration Forms and Special Quarantine Declaration Forms through a self-diagnosis app. Nationals and residents of South Korea are required to install a 'Self-quarantine safety protection app'. Chinese nationals who are traveling on business under the Fast Lane program and their family members are exempt from the quarantine requirements; however, they must self-monitor their health conditions for at least 14 days before departure and must hold a medical certification of a negative COVID-19 testing result issued within 72 hours before departure. They will receive an additional test upon arrival, after which they must stay at a designated quarantine facility for up to 1-2 days until receiving the result. Once receiving a negative test result, they will be allowed to end their quarantine.
Nationals of Mongolia, Russia and Thailand are restricted from transiting through South Korea on their way to or from those countries, and all foreign travelers who have been in Bangladesh, Kazakhstan, Kyrgyzstan, Pakistan, Philippines or Uzbekistan in the past 14 days must have a medical certificate with a negative Coronavirus (COVID-19) PCR test result issued at most 48 hours before arrival to enter South Korea. The certificate must be in English. Transit passengers will receive a temperature check on arrival in Korea. Symptomatic individuals will be subject to a COVID-19 test and hospitalization if found positive. Passengers who do not show symptoms and/or test negative may continue their journey. Transit passengers at Seoul Incheon Airport require a ticket/boarding pass for their onward flight to their final destination. Travelers should confirm with the airline(s) before departure that their bags have been checked through to their final destination (as transit passengers are not able to collect and re-check in baggage on arrival in Incheon Airport).

Cons: "Actually nothing is my dislike things."
Pros: "Roomy seats on JAL flights - their actual airplanes. Horrible when they codeshare with american and use American Airlines planes."
Cons: "They have to take the prize for having the absolute slowest customer service in the world. When I booked my tickets, I emailed customer service to make sure I didn’t get a center seat. It took them two months - TWO MONTHS - to email me back, to tell me there was nothing they could do. I also had to be reticketed on my flight from Tokyo to Hanoi. It took them 3 1/2 hours to do this. I had to sit in the airport for 3 1/2 hours to get my ticket changed. Unbelievable. They could’ve chiseled it in stone faster than they issued it."

Cons: "How long it took the flight attendens to come back and take trash and out trays for both of the meals. It made it super uncomfortable in the tiny space available. Also, not enough knee space, especially when the person in front of you puts there seat back. I flew with American Airlines on the way to Japan and I had plenty of room but I wish it was the same coming home."
Cons: "I reserved Korean air but it was Japan air line. I was really difficult to web-check in to find my reservaiton."
Pros: "Nothing at all"
Cons: "I purchased a flight through one of the participating vendors on kayak for a major airline and accidentally chose the wrong departure date. I never received a confirmation email and therefore missed the flight. I understand and take full responsibility for booking the wrong departure date but when I tried to change it after missing the flight I was told that the airline policy was to charge a $300 change fee plus $30 for the third-party vendor. Because this was booked as a round-trip this vendor was attempting to charge me $330 plus the full price purchase of a new ticket as the "change fee". For some reason I was unable to explain to the person on the phone that it made no sense for me to pay full price for a ticket plus give that vendor an extra $330. I was forced to eat the entire round-trip ticket and of course save $330 by just hanging up and booking a new flight. I have course book a new flight directly with the airline. I could not even fly standby on the next flight with the airline because they told me they were unable to assist me in anyway because I booked through a third-party vendor. There were plenty of seats available on the next flight and I would've been able to fly standby had I purchased directly from the airline. Never again"
Pros: "The flight's timing and airports are perfect for a short weekend getaway between Seoul and Tokyo. JAL service is also perfect!"
Pros: "Seat was very comfortable and had many games and movies to keep me preoccupied during the flight."
Cons: "I didn't like that the crew at check-in and the crew on the plane told me different things. The crew at check-in told me I could keep my purse with me, and the crew on the airline told me I had to put it overhead. Please be consistent! Flying is very stressful for me, and I want the staff to make it as stress-free as possible. As for boarding, I wasn't allowed into the gate until an hour before. What really bothered me was that they had already let some people into the gate and shut some other people out. Either let people in or don't. Don't follow the rules halfway because then they won't mean anything. I was very shocked by this and have never experienced this at any airline before. All I wanted to do was sit down and relax at the gate before boarding. If this ever happened to me again, I would not fly with the same airlines. To think that this was a JAL flight, with such a high reputation of customer service, makes me even more wary of booking a flight with JAL. I didn't appreciate being treated that way, and I will not tolerate it if it happens again."
Pros: "The food and plum wine. The entertainment packet was nice too!"
Cons: "The folks coughing on the plane."
Pros: "The flight staff on Japan airlines was great. The meals were excellent, and the flight itself was fairly comfortable."
Cons: "Our flight was rebooked without notification leaving us sitting apart for a 12 hour flight to Japan. This left us with one option of an unexpectedly upgrade in order to sit next to each other"
Cons: "The main entree was not very good."
Pros: "Good food and punctuality"
Cons: "No English subtitles for English speaking movies"
Pros: "Japan Airlines is very good. They have good service, safety, and customer care."
Cons: "Economy seats are a bit tight."
Cons: "Some turbulence awoke us midway through the overnight flight."
Pros: "Very clean. They check the bathroom pretty often un-like AA. Good food."
Cons: "I always prefer this airlines."
Pros: "Food and beverages service .very pleasant attendants..economy tough on 11 hr flight..fee seemed reasonable though. .ovreally nice experience"
Cons: "11 hr flight"
Pros: "Short flight."
Pros: "Service was excellent - Flight attendants were friendly and professional."
Pros: "The upgraded seating."
Pros: "Service & Food"
Cons: "Food was below standard."
Pros: "This complaint is more targeted at American Airlines, which handled the New York Washington leg of the trip. They provided free food such as sandwiches and drinks at the gate due to the 2 hour delay."
Cons: "Red eye flight delayed for 2 hours. Then delayed another hour on the runway. No in-flight enternmaint, which would have made it bearable. Descent into Washington Reagan National freaked me out because the plane was flying eratically while being so close to the ground and recognizable landmarks."
