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

Courteous crew and effective service on-board. Good leg room. Areas for improvement: 1. Limited menu meal menu options. During checking there was no means provided to select meal option. On our return flight the first meal had Pork and Beef options only. Fortunately the second meal had Chicken as an option. Otherwise we would have gone without meal through 13+ hrs of journey, 2. Limited choice and very limited number of movies and TV shows.

I booked this airline twice. The first time, they cancelled the flight due to destination weather condition but without offering any optional flight but only a cancelation notice sent via SMS. I had no choice but to re-book United airline with the same travel date and destination. (no impact on the weather condition Air Premia claimed) The second time, my husband missed the flight due to local traffic in Seoul. Normally, all major airline would helped you to re-book the same flight next day with changing fee only. But Air Premia offered nothing and only requested my husband to re-book a full price ticket.

Don't splurge for the Premium Wide Economy. They compare it to business class. This is not business class, and the seats are very uncomfortable.

For the second meal, the different food choices ran out both times so we were only offered one.

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 crews were friendly, professional and courteous. Checking in was easy and smooth. The best part is, as we all know, 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.

Food quality is poor. Flight attendants are very friendly and professional.
