Austrian Airlines help and service was fine, but Kayak misled us into believing we had purchased a Business Class ticket. In fact, the tickets were only upgraded Coach Class tickets with luggage restrictions that belonged to the Coach Class. Very disappointed! Paid over $$$$ 9K for the two tickets. Very disappointing!

Quick and organized boarding process, friendly staff but not as many snacks and drinks as the previous flight overnight

Landing was a little hard. Food was not great My prior review was for the flight to nyc too

Landing was a little hard. Food was not great. No options.

Five star experience all around except for my seat, which was broken. It would only go down 70%.Of the way. It defeats the purpose of buying a business class ticket if you don’t actually get to lay flat..

I love this airline.God bless CAO and the whole staff of this company

It was on time. Snacks could have been provided for free.

Tirana was crazy check in and getting bussed to another gate. Both Germany stops were intensive customs but organized, but that wasn't the airlines problem. The crews were fabulous on the planes. The announcements were not easy to understand in English, slurred speech. Customs inthe US were fast. We waited for luggage, three later arriving planes had their luggage and left before us

Business class old style from 10 years ago. Ok for short flights but nor for 12 hours journey. The passenger near the window have to jump over the passenger seat aisle side or wake him up to upright the seat. That’s not the business class that you expect on long night flight. Seats are not so confortable. And believe it or not no wifi!

We have travelled on 13 December with Austrian Airlines from Yangon through Bangkok and Vienna to Varna. The first flight operated by Thai Airlines was nice and comfortable. I wouldn’t say the same thing about the next two flights which were operated directly by the Austrian Airlines. During our flight from Bangkok to Vienna:  > The service was very poor – serving of food and drinks was disorganized, late and not combined, the stewards were walking back and forth without doing anything substantial for the passengers. Even the morning breakfast was very late with a cup of coffee almost while landing (after a reminding).  > The food itself was OK-ish but for a 12-hour flight, there were no snacks/bites in between dinner and breakfast as it is with the other airlines.  > The cutlery was wooden, most probably recycling, but very unpleasant to eat with.  > The stewards were not rude but not friendly and/or helpful  > And also, half of the passengers had travel sets, others did not. The flight from Vienna to Varna was another surprise: firstly, the flight was late and secondly, they were serving only water free, even the coffee was paid, so were the snacks, but we had to pay to reserve seats. The whole experience is as if it was a low-cost airline. All in all, I wouldn’t recommend using the services of Austrian Airlines: the ticket prizes are quite the same as of the other carriers flying to this destination and you would have much pleasant time.

The 50 € boarding fees per ticket are completely unjustified. I lost all my savings because I arrived at the counter barely 5 minutes late (2hrs and 55mine before departure). This feels like an unnecessary penalty. It's especially disappointing considering the initial flight was canceled by WizzAir. I expect a partial refund of the 196 € paid for the boarding.

Boarding kept us waiting for ~15 minutes in the sleeve. Other than that, excellent for a low cost carrier.

Low cost carrier, you get what you pay for. Cardboard-quality seat, no recline, minimum pitch, bus-to-board service (no jetbridge), and overworked/underpaid flight attendants. But, they got the job done on-time with no major catastrophes.

The behavior of the front desk and lack of explanation of hidden fees and prices in emails send pre-flight marred things up. 1 star

2 hours delay, very disappointing, at least they didn’t cancel at all as they do often

I miss my flight due to boarding pass won’t load up

Flight schedule was modified and the final departure time delayed.

Big delay because of the weather but communication not so good. Boarding already late (due to tight schedule on Wizz side). When you get in you are hurried every second even if you still need a few seconds to arrange your bags. Food far away from how it looks in the catalogue and right on row 8 already out of chocolate although you are supposed to receive one for a menu. No replacement was offered.

The border control opens at 4:30 so there is no point in going in early as the wizz email suggests. Our flight utilized a plane with plastic seating which was really uncomfortable.

Check in took very long. All three priority agents left for lunch or something and the line did not move.
