The free wi if was highly appreciated and worked very well. Staff was great!

Fine. It was a 25 minute ride in a tiny plane that left 20 mins late

The only issue was a short window to make my connecting flight, and nobody to assist me in finding my way to the next gate.

Just ok. No much of a great travel experience. If you need point A to B they are ok.

More leg room, great if crew could move people before flight (ie if 3 in a row, offer to move 1 or 2 to an empty 3 seat row rather than let people move themselves after takeoff

Very bad experience during the boarding, the Aegean employees were very rude, and impatient with the passengers

Flight was late, boarding totally chaotic, seat uncomfortable, food good, attendants and pilots good.

Priority transfer bag left behind in Amsterdam causing extreme difficulty and inconvenience on arrival destination Athens

Short flight. They served drinks and food, but the flight was full and had to put my hand luggage under the seat.

2 hours delay on the plane causing us to miss our connection

No delays, helpful staff, well organised. The check in and boarding procedures ran smoothly. The only thing that put me off is that the meal had spicy peppers in. I would have appreciated at least a warning (if i couldn't have a choice) so as to simply not eat them because they were too spicy.

The crew was attentive but not intrusive, and was always kind in every interaction.

Austrian was not the issue. Kayak was terrible The flight was canceled. Frustrating but it can happen. The worst was Kayak's customer support around re-booking. I have chatted with a bot, than with a person who insisted the flight was still on as originally booked. while chatting i went on Austrian web page and told the kayak chat lady that the flight is shown as cancelled. She said she will escalate this and that someone will contact me within the hour. When I have asked her to give me the details of the flight she sees, She gave me the general A to B and return B to A. Totally unhelpful. After two hours I contacted them again, They were still saying the original flight is as scheduled and when I explained again I was told I will be contacted within 2-6 hours. NO ONE CONTACTED ME EVER SINCE! I have than contacted Austrian directly and was rebooked on a difficult flight. Kayak continued to send me irrelevant updates about my original flight. Terrible customer service at time of need.

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.

Austrian airline they cancel my fight , and the couldn’t give me flight , they said only available flight 4th and after , I sacked for refund, even from you KYAK , and tell now no any refund , because what happened I lost more money because I have to stay in hotel and then I buy new ticket

the flight was canceled, and I had to stay more than six days at hotel . waiting . then I had to buy new ticket. really it was very bad experience, and I lost a lot of money and time , and your airline said sorry

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 bought the ticket a month before my flight but checked in couple hours before my flight and had to wait seat assignment just before take off. On top of that there was not enough room in the overhead bin for my luggage.

The baggage arrived damaged and i spent EUR 300 on the baggage a month ago. No responsibility from airline or the handles.

Premium Economy is good value in comparison to Business Class. Not all the perks of Business but a lot of leg room and wider seat and elbow room. Food was very good. I even asked for a Gruner Veltliner wine which was not on the trolley and the attendant went into Business/First to get me a glass. Nice little touch. I would like to have a wider selection of music -- more 70's-80's (guess how old I am).

Boarding was a zoo. London ground crew was useless. Poor communication regarding where to line up. We were group 2, and everyone was jammed in together. Ground crew didn’t seem to care.

Horrible flight attendant in back of economy that screamed at me, have already reported to United. Horrible food - for Gluten free, why would you assume the person is vegetarian? I was served some kind of horrible curry bean paste and multiple cold rolls and soggy vegetables with no seasoning... um no!

I was at the airport on time , I checked in my luggage . The plane was delayed and the gate was change. The flight board did not give information . I did not get chance to fly. I am going to make a claim for it

Never flown with LH before so all in all wasba good experience. Also good to know that approx 24hrs prior the flight opens up for being able to organise the seating free.

This flight space was way better than our international flight. Efficient boarding and comfortable

It was a short flight, no real service (which is okay). Very bumpy because of weather.

I'm Canaadian. I hate Air Canada. I used to give them a pass on their international service. No longer, They suck across the board now! Old planes, exhausted staff bad food and shitty entertainment. Your seats need reupholstered! Start with that...

Good experience. Food was great and passengers helped rearrange seats so our family could be seated together

Great flight. Left on time, not very crowded. Quiet and the right temperature.

No eye patches , socks given out for overnight flight! The snack on the short haul was a cube of chocolate! The seat was uncomfortable for a long haul - not enough cushioning!

My worst flying experience so far. This flight was delayed a total of 42 hours and diverted to New York before it was finally cancelled. It was delayed 4 and a half hours in London. As we were scanning our boarding passes at the gate they advised that the flight was being diverted to JFK since the delays caused us to missed the open hours for Charlotte international customs and immigration. We were assured multiple times by airport personnel, flight attendants, and the Pilot that we would land at JFK go through customs and immigration and then reboard the plane to fly to Charlotte in the same night. When we landed in New York the pilot advised us as we were retrieving our carry on luggage that we were delayed till 10am the next morning and to see guest services to get a room for the night. During this time I had to purchase a room for a family member in Charlotte which drove over 4 and a half hours to pick us up from Charlotte. This could have been avoided if American Airlines had been up front about the delay. Then after standing in line for over 2 and a half hours at guest services we were taken by taxi to a hotel 30 minutes out of the way. Luckily I looked for other flights that night and found one at 8 am to get on. The initial flight which we were scheduled to fly to charlotte in was delayed 12 more times and was finally cancelled 42 hours after it was supposed to land. I am unaware of what happened to the guest that were supposed to fly on the flight after we were placed on another flight but 42 hours in delays for a direct flight is absolutely ridiculous.

Really quick check in and security at Heathrow Terminal 5. Staff on board were lovely and very friendly. Could have provided a few more drinks on the flight but they were available at the back of the plane.

Flight boarded and took off late for unknown reasons. Crew insisted we check our hand luggage due to full flight, which it was not even close to full. Then had to wait almost an hour a and a half for the hand luggage to come onto the luggage belt since it was loaded last. This came after many hours of traveling pregnant with my 6 year old daughter. Really didn’t appreciate the unnecessary delays. What the hell?

Left late. Crowded like cattle. Standing and waiting. Food on board getting worse.

Terrible- the flight time was delayed and then I was denied boarding because I arrived at the new time of departure

Flight delayed an hour due to plane maintenance issues after getting in line to board. Issue was plane galley ovens which eliminated hot meals for overseas flight. Cold selections were limited due to availability. Drink and meal service (already an hour delayed) was very slow. Upon arrival in Nashville, had to sit at gate for about 15 minutes before disembarking with no explanation. Local police then boarded plane as we were disembarking so maybe that was the issue.

Boarding good. Seats uncomfortable when lie flat. Food was awful. Tasted stale and chicken was dry. No live tv or flight map. Had to pay for internet.

Poor technical details on this plane. 1) There was no WiFi on an 8 hour long-haul flight. So no work could be done. That's below the standard expected for airlines these days. 2) The power outlet at my seat was busted and not working. 3) The headphone jack was loose and I had to keep adjusting my headphones to get good reception, or when it slipped out. - The flight was delayed to due mechanics. Sometimes this can't be avoided, I understand, and it's a big inconvenience to arrive that much later when traveling across time zones (then arriving at 4am from the prior time zone). - Also unique to this flight, the northern lights were visible on the right side of the aircraft, but I only found out after we landed (b/c again no wifi). I understand there are considerations about people being out of their seats to look, but I feel extremely disappointed and resentful that I wasn't told so that I could have a chance to look at this probably once-in-a-lifetime cosmic event from a view in the sky. - Flight crew was otherwise friendly and helpful.

Our flight was delayed by over 6 hours. We then had to deplane, stay overnight in a hotel then fly out the next day, 23 hours late.

I would have preferred something lighter for the second meal. Maybe a small sandwich .

The flight was delayed 5 hours and I'm and invalid,I wan a refund for this

The cabin crew on that flight were super fantastic and super helpful. They were so polite and considerate that i felt i travelled with a 5star airline.

Delayed delayed delayed - always with Wizzair. Staff were friendly and well mannered but clearly the company is unorganized and the aircrafts are outdated.

It's a budget airline. Great for short flight. Smooth landing.

4 hr delay and only told less than 2hrs before. Only given water and nuts on the flight as complimentary service. Left to wait in rain before boarding.

To be honest I did not like anything. Communication to why my flight was cancelled mid air 2 and half hours into my flight. Customer service desk were not helpful with providing information or a solution on what can be done.

I have been treated unacceptably by WizzAir aircraft crew in a previous flight, they threatened me and abused me, and I received an OFFICIAL written apology, but only two (2) months later. This flight had no such unacceptable behaviour, but it's not nice to be left waiting in the walkway (from gate to aircraft) for a long time, just so that the 'boarding' appears to be early, even if actual departure is not.

What I liked new airplane Sitting was extremely uncomfortable! Crew not smiley at all Always chewing gum

The flight was cancelled just 4 hours before the take off...

No food on board. Not comfortable. Had to move seats was delayed more than 3 hours.
