Seats are extremely tight. It was a 45min flight, no food, no entertainment.

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.

Very nice staff, airplanes, and an excellent value in premium economy.

First time flying with them and was pleasantly surprised. I had a premium economy seat which is very similar to some other airlines regional business class product. Seat was large, pillow was provided, huge amount of leg room, entertainment was available (only Korean shows), and lunch meal was served between Narita and Seoul. Really enjoyable and affordable

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)

Although I am a lifetime Gold Premier member on another airline association, I was placed in a inside passenger seat on both legs of my journey from SFO to HKG and onward to NRT. However, i was lucky enough to have befriended two other passengers (who were related) in my row (row 62) and therefore was kept entertained with conversation for a large portion of the overnight flight from SFO to HKG. Normally, on a Star Alliance carrier, I typically can have the seat of my choice (aisle seat) and also a Premier seat (wider and longer legroom). I was a bit disappointed that no recognition of my Gold Premier status was acknowledged by Cathay Pacific on either of my flights on Sept 26-27. The food was actually very tasty unlike the typical economy class menu. Also I appreciated that the dinner drinks were served first (prior) to the main meal on the HKG to NRT portion of my flights but drinks were served AFTER the meal had been distributed (less appealing for thirsty passengers). I was happily that there appeared to have ample cabin space for most everyone's bags ---although I did have to pay more than $400 in extra baggage fees as I had brought 4 bags with me Overall, I was impressed by the diligence and professionalism of the flight crew.

In between two meals period they're not providing something like banana / cup noodles or bugger. It's really fell sad that I was asking have to wait for 3 hours for second meal. (breakfast)

The crew are timely, friendly and professional. I was very impressed.

They overbooked the flight and reassigned my seat. To add insult they lied that my assigned seat was broken and promptly gave it to someone else

Jain veg meal I opted was super in taste but there was no sweet/desserts with it. I was a big missing in the meal...Please add some sweets to end the meal with 😊

The meat-and-rice combination was a good idea, but the food could use some improvement. The meat looked a bit mushy and almost like ground meat, which wasn’t very appetizing, and the flavor was just average. Other than that, everything else was great.

Weather delayed arriving flight and even though I made the connection, my luggage did not.

Great! Internet is below its competition. Poor connectivity quality and speed.

Great. Efficient boarding process with the face recognition. Plenty of cabin space for luggage.

Average flight for which I paid too much for on a last minute purchase.

Amazing experience, tonnes of leg room, great crew and smooth flight. Especially for this price for business class.

Great Value with Tway Airlines I highly recommend flying with Tway Airlines—especially if you're looking for a budget-friendly option. While the lowest fare comes with limited luggage allowance, it suited me perfectly since I was traveling light. Check-in and boarding were impressively fast and hassle-free. The ground staff and cabin crew were exceptionally polite and courteous throughout the journey. Although the aircraft was an older model and lacked inflight entertainment, this was a minor trade-off considering the ticket cost was nearly 70% lower than typical fares on the ICN–FRA route. If you're focused on value and efficiency over luxury, Tway delivers a smooth and pleasant experience.

I liked cleanliness, comfort, kind staff. I thought communication about meals could be better. We did not know how we were supposed to ensure we had food and drinks in our booking

ok flight, but charged for everything. water, food, baggage. no free water available, I had to plead to give me water to take medicine.

Need to consider about zero entertainment services and lack of flight information!

I can't board the 2nd flight due to the last 1st flight. In the 1st flight check-in, I can't board due to the stupid problem of K-ETA visa. The booking system and the flight company should inform the customer a few days earlier. This is the worse experience in my life. I won't use KAYAK and the airline anymore. My friends were also surprised about this stupid situation. I won't use KAYAK and T'way anymore.

I can't board the flight due to the K-ETA problem. You should inform the customer clearly a few days before the flight. I can't cancel/change the flight now. This is the worst experience in my life. I also never hear about this kind of bad experience. I won't use the booking system and the flight company anymore.

Captain smooth landing, Crew efficient and helpful. We saw Mt Fuji from the plane. Thanks.

On time and smooth flight from San Juan direct to Sint Maarten.

Just to be expected on a budget airline. Since all the flights were either late on the evening it would help to offer some food for purchase Since you tourists cannot buy decent food withoit local vaccination record in hong Kong this would really to help Using phone to submit electronic data is great but for the elderly this is a hassle

Flight cancelled without notidication, had to book an emergency replacement flight at the counter
