Terrible
미국에서 예약하려고 하는데 어떤 날은 결제가 되고 어떤날은 열번을 시도 해도 안되네요. 개발자님들
해외사용자들도 쉽게 사용할수 있도록 신경좀 써주세요. 유나이트항공 정말 잘되어있습니다. 참고하시면 좋을 것같습니다.

Cannot sign up
The app keeps telling me In have 4 identical characters in the birthdate, I do not and what is that error about?
★★★★ nomercynomercy 3/3/2025 v3.0.7
Such a shame that I can’t give them 0
Terrible app
Nothing works

쓰레기
진마켓 3시간 기다리다가 겨우 들어갔더니 갑자기
업데이트하라고 뜨고 못보네요 0.5점도 아깝다
★★★★ Qwermnbvlkj 12/12/2024 v3.0.4
Terrible
This app doesn't work, I'd like to book a domestic flight but it's impossible. Why have an English version of the app if you don't accept reservation from English speakers?
JinAir must lose a lot of business because of their bad app!
★★★★ 미카04 11/18/2024 v3.0.4
저가 항공 답다
대가리에 든거 하나 없는 개발자들 고용해서 만들었는지 진자 이건 무슨 비행기 한번 예약하는대 암걸리게 만들었네. 아 정말 역겹다.
★★★★ General Gao 10/26/2024 v3.0.4
Can’t use the app at all
This is a case of the other 1 stars being totally accurate. I downloaded the app and have messed around with various ways of accessing the internet as the error message I receive says that my internet connection is the problem. Nope, it’s not - this app just doesn’t work. Also, I’m in Korea trying to use the app so I find it sus that the problem has something to do with overseas bots: I’m in Korea with a Korean IP address. Seriously - this app is terrible: don’t bother trying to use it.
★★★★ ShoshinSeattle 10/14/2024 v3.0.2
Unusable
I touch the screen. Nothing happens. I delete the app and reinstall it. Again, nothing happens. I tried this in the morning and now in the evening. The result is the same. The app is useless.
★★★★ hwalker84 9/17/2024 v3.0.2
Doesn’t work
Keeps saying “Your network connection is experiencing delays. Please check the connection and run the app again”. There’s nothing wrong with my network connection.
★★★★ isprainedmyuvula 7/1/2024 v2.5.25
Unusable
Cant pass the Cloudflare initial test, despite every other app and website I’ve used with it has.
Seems a little unnecessarily security focused just to give a business my money, no?
Okay, T’Way it is!
★★★★ Vachgo 5/26/2024 v2.5.21
Horrible app
Can’t even load past the robot verification. Completely useless. Useless website as well. Trash.
★★★★ Vixen from Philipoines 6/26/2023 v2.5.18
Useless
Doesn’t work. I registered in the website and download the app so i can choose a seat for my upcoming trip and it won’t even let me view my booking so i can pre select seats.
★★★★ qchuddhi 6/2/2023 v2.5.18
Makes flying more stressful
Horrible app that provides essentially nothing. Can’t even check in. Fly Korean air or something else if you can
★★★★ gooddddddthvu 12/10/2019 v2.2.0
ㅋㅋㅋㅋ
앱 노답
★★★★ Ramatuzzi 8/18/2017 v2.0.4
Garbage!
I have used more than 20 airlines apps. This is the first I cannot even get into my reservation. It has an impossible login procedure that asks for "PNR" (what is that?!?!). Anyway, email, reservation code and ticket number is not enough to access my flight, let alone check in on line. Get some professional to make a decent app!
★★★★ 예약? 7/31/2017 v2.0.4
예약할 때 다음 단계로 넘어가기 위한 '다음' 버튼을 누룰 수가 없네요..
