This is truly the worst travel experience of my life. The UK ETA program had a technical failure, and I was stuck in limbo for 24 hours, unable to board my flight and unable to navigate anything in my itinerary. I had to rebook an entirely new flight and I’m now out doubled the money. Unconscionable.

This is truly the worst travel experience of my life. The UK ETA program had a technical failure, and I was stuck in limbo for 24 hours, unable to board my flight and unable to navigate anything in my itinerary. I had to rebook an entirely new flight and I’m now out doubled the money. Unconscionable.

Excellent flight. The crew was exceptionally attentive and organized. Attention to details is unmatched.

Accessibility serious problems in Viena airport making it seriousely difficult in in-between gates and boarding travel. Pretens of breakfast and service care in the economy pathetic.

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.

The problem is with Kayak and Underpricer. You overcharged me for a change fee and for seats that I did not get. You owe me $600

From all the segments I flew it was the only one I did not get the option to choose ni seat, I did not get the quality of seat I had paid for. Crew was nice, airplane was clean, but no food, only water and a small courtesy chocolate. Everything else you had to pay for.

Management and staff att viena wasn’t professional,and they are not good by how to communicate and solve the problem, I was shocked , as I know Austrian airlines was amusing Thank you

I been flying with Austrian for few years, they never failed me.

Food: my selection was pasta with vegetables, though it was potatoes not pasta. Breakfast was 2 rolls and some sort of spreads— not sure what they were. Worst thing was that we had to wait for over 90 minutes for our bags to show up at O’Hare

Worst airline I’ve ever been on. Would not recommend to anyone no matter the cost.

The chairs don't recline and the food for sale didn't looks as appetising as its prices would suggest. But that's a low coster for you. Orher than that, the flight was delightfully uneventful.

The flight never took off because two naughty kids, Donnie and Bibi, did a silly thing. Started a war.

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.

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

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.

Il n’y a pas eu de vol du tout puisque celui à été déplacé à la veille sans aucune information. Aucun remboursement ni service client non plus. Scandale !

A GOOD IDEA IS TO SEND TO ME BOARDING PASS IN ADVANCE SO I DONT HAVE TO FIGHT FOR IT

Attesa lunga nella comunicazione del Gate e dopo l'apertura del Gate

One hour delay, landed at midnight, my hotel did not accept late check in after midnight. I had to pay for another accomodation last minute after I landed. Wizzair customer support did not reply when I asked for alternative accomodation. Very poor experience overall.
