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.

Friendly staff, always good food , as comfortable as it can be in economy

Business class is not worth it. Not comfortable and old plane with no privacy or enough space unless you on the single seats

We didn’t fly into Neuark , because it departed without us . We ran to a closed gate , and no staff to assist, then to a customer service center that was also closed, then briskly walked (20mins) to another customer center and got a ticket , waited 2 hours , got a flight to JFK instead, because of the time delay we Ran to catch our train home , and again our luggage arrived 3 days later delivery time at 3:45 in the MORNING!!!! Crazy!!!!!! Took a few days to shake off this disappointment of your service. You’re an embarrassment to customer service .

A bellow average experience. A delayed flight , no staff to assist , running and panic to connecting flight , 2 hour wait for customer service. No luggage when we arrived , luggage delivered 3 days after at 3:45 AM !!!! Much stress and anxiety from this experience. Please repair your Brand .

My luggage was lost and I did not receive any compensation

Pleasant up to Vienna. Afterward (Vienna- Zagreb) was an horrific experience

Leg room and seat back not a good recline (middle seat)

ontime and super quick boarding and disembarking. I made it in 6 min from airplane through passport control to the train platformin Cologne. Amazingly quick airport.

If you buy a cabin luggage, but don’t need it for your kids, so you will end up with mixed priorities. And you will need to use non priority line

People at the gate were the worst I ever met from Ryanair

Flight details on public information screen were misleading and wrong.

all fine - did not have food - there was no entertainment

Long delay was made worse by lack of information and long time in queue waiting for the plane to arrive

Be on time and staff on airport could be a bit more nicest

Crowded, little leg room, little lateral room. Hour late, then all funnelled into a small room with a couple of bench seats for 150 people. Most sitting on the floor or standing for 30 mins before chaotic boarding.

1. Too long on board without air conditioning. 2. Very very long-tiring walk to exit gate.

Worst experience ever. First time and last time with Ryanair. I'm not a cow.
