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.

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

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

I flew on Zip Air on the way to Asia so I can compare. The two airlines are night and day. Air Premia was so amazing compared to Zip Air. I have flown Korean Air in the past and I honestly don’t know the difference between Air Premia and the “non-budget” airlines. My Air Premia flight provided me two bags whereas I had to pay for Zip Air. On my under 11 hour flight, we were provided two full meals! The flight attendants were so kind and polite.

For the price, the overall experience was what I expected. The prices were fair and competitive, the staff friendly and more responsive than other airlines, and seating spacious. The downside was food portion size, but I'll gladly pay a few dollars more for the hot noodles or other supplemental snacks, given the more affordable ticket prices. I don't mind the absence of Hollywood movie programming if that leads to inflated ticket prices. Wi-Fi worked well. In addition to spacious seating for the Wide Premiium, I'd suggest foot rests to complement the calf rests. There're problems with booking Air Premia tickets at the home website. The underlying app engine won't process non-Korean credit cards, which is a major oversight, probably hurting the company's bottom line. I can go to Kayak or a third-party website to book Air Premia tickets, but it's an awkward work-around when other airlines don't have to resort to this tactic.

As it's a budget airline it's pretty basic. But the quality of crew and plane is excellent.

Maybe the reimbursement voucher should have been larger than a 10k won. That voucher is only for refreshments. The flight was delayed or pushed to more than 5 hours. It should be more than just 10k won and it was already past midnight. Some people or passengers like who was already there 5 hours prior to the original flight departure. 4pm** That was the only unfortunate thing about it . Other than that it was good .
