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

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)

The option to check in the carry on bag for free was very convenient. If one checked bag could be included in the ticket price that would be even better.

It was very good, ,especially the working people in the plane, they are so polite.,thank you

They never gave any meal during the flight. We’ve flown for years and then doing this now is ridiculous.

Austrian airlines lost my bag in Vienna and it took 2 days to find it and deliver it to me

Good value for the money. Good leg room. Take off and landing very good.

We were diverted to warsaw and there was zero information. We were just forced to disembark and off we go good luck the reat of the way. We all had to go our ways to find a way home!!!! Horrible horrible and it cost us alot of money to get a hotel and trains 4:30 pm next day.

On time was excellent, not serving any water and deliberate seatings apart is deplorable.

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

Delayed delayed delayed and then cancelled very late not allowing for too much time to find a room for the night

Blood contaminated tissue was stuffed to the back of the seat in front of us.

Great flight, departed only 10 mins behind schedule off the aircraft and through security in less than 15 minutes. Love flying from Cardiff so easy a quick from entrance to duty free in less than 10 minutes 😀

My flight was delayed 1 hour. My Mood was not great

Lord knows why they had us start boarding when the plane wasn't even there, staff weren't welcoming and the couple next to me travelling with a young child had a nightmare with the baby changing facilities.

This time round it was very good, flight delayed by 30mins but capitan put his toe to the floor and made some time up!!
