If you have to switch from Terminal 2 to Terminal 1 it is a bit of a hassle. That needs to be fixed. I should not have to go through two separate security checks after landing in the transfer areas.

It was for the most part a 10/10 they said they had entertainment options but all they had was old movies for streaming from the mid 2010’s so like 10 years ago

all good for a very budget flight - well priced and excellent service. Will fly again

I appreciate the economy price of the tickets. The long flight made the comfort level on the lower average side. Wi-Fi connection was not consistent but working. Overall, I would fly again with zip air but next time get the flat, premium seats with the amount of money I would save otherwise.

Comfortable seats and lucky no one was in middle seat. No water on the plane. Plane was on time and staff was fast.

You get what you pay for and nothing more. Wanted a cheap flight and that’s exactly what I got, though it’s human nature to wanting to feel like you got a good deal as well. There was none of that here. I was cheap and they were too. Got to my destination safely and that’s all that really matters.

Nice service. I wish it could provide hot water on the flight.

Flight was seamless. Free wifi helped pass the time. Food was okay, just make sure you pre order or pick something up from the airport

Wifi could have been better. Arrived 55 mins earlier than scheduled :)

Best part are two crying babies throughout the whole 11 hour trip

Inflight WiFi would lose connection when you don't continuously use it, and would sometimes be difficult to reconnect. Food quality could be a bit better. Other than that, it was excellent.

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.

Thanks to the kind staff for locating my lost onamori.

Quite ordinary, as might be expected of a budget flight. It was difficult to understand the instructions unless one speaks Japanese, and the seats were quite basic.

Very easy process overall. The staff communicated well and everything was efficient.

Very affordable, smooth check in process, flight attendants were safe and kind, lots of flight availability within Japan.

The seat is so bad Can’t recline the chair

For Travelers with babies, if they can be supported by allowing to carry the Baby stroller upto the Airplane gate, and not submit at the Check-In counter. it will be very convenient. Thankyou.
