Quick flight. But cabin crew were very noisy and talking too much, especially when we were seated at the back of the plane trying to sleep through the night .

My ticket was for Premium Economy and all the seats were taken, I was placed in Economy class and I’m looking for a refund.

Unfortunately delayed 2 hrs due to faulty tyre.. which had to be changed, but better safe than sorry.

The delay was an issue. Other than that. Every thing good

Hi vergin Atlantic service was good but the flight ticket agent travel up charge me extra 57 pounds as a airport charges, actually I refuse to pay but they say if I not pay £57 then they say you will not be able to travel from Heathrow to goa ,so for me there was no option and it was just 3 day before my departure so i paid, so please look in to the matter. And I have a receipt of £ 57 as well .thanks

Staff didn’t check cabin well for landing seemed more interested in chatting to each other. Food was poor and differed from pre order.

We were in the last group to be called to the flight - which was 30 minutes late taking off. While we were lucky enough to have been given bulkhead seats (due to a medical condition I’d told them about beforehand) the seats weren’t particularly comfortable. A crying baby for the whole trip made things worse, so the crew managed very well with coping. The final thing I’d say was that there wasn’t enough food served during the flight.

Very good. Glad we had Premium for the flight out.

We flew Upper Class from London to The Turks and Caicos. Check in was amazing. Our ldriver too us directly to a special entrance to terminal 3. It took 10 minutes to check in and clear customs. Amazing! The VA lounge is large and comfortable. Boarding the flight was easy and without a wait. The crew was excellent. But the seats were awful, strange and uncomfortable. Having a comfortable flat bed seat is the reason we pays 1000s extra. The VA 787 uses a reverse herringbone configuration. Look it up. You have your back to the window and are facing the aisle with no privacy. Turning the seat into a bed requires assistance from the crew so not very spontaneous. . The food was ok. A bit tasteless and meager portions. Had to pay for WiFi. I believe VA has other configuration on their dream airbus flights. Lots of stuff about all this on YouTube where you can see what I have been describing. I can not recommend taking VA on a long flight with these seats.

Schedule and on time departure and arrival were great. The crew was good, but a change in aircraft bumped many of us from our expected seats. It was a crowded flight, but the cabin crew did their best to keep things under control.

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

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).

There were a number of passengers scheduled to transfer to the flight from Vienna to Warsaw. None of them made it because the crew failed to assist them in getting to the gate for the Warsaw bound flight in time. It could have been done very easily with proper assistance.

I am Star Alliance Gold which meant nothing at security as my partner, who was on the same ticket, couldn’t come through with me which meant I had to wait for 20 minutes for him to join me. For a hub airport the lounge was small and uninspiring. We told staff of our security experience and they informed us it was like this for everyone. Isn’t this is an Austrian Airlines hub? Boarding was a nightmare as there was only one person at the gate and again, I had to go through without my partner. The boarding was supposed to be in groups but a bunch of travellers with lower groups were crowding the entry level. After I managed to get through I found myself on a bus waiting with 3 others for 15 minutes as the checkin had failed. Then only to find everyone else coming onto the same bus. My partner and friends actually beat me onboard. The crew were young and unable to control the crowd allowing people to stand in the rain instead of getting people to their seats promptly. During flight we were only offered a cup of water & a chocolate. Not impressed with Austrian Airlines or their Vienna hub airport and plan not to use them again if I can help it!

Overall pleasant flight . The lunch was exceptional! Delicious chicken curry with perfect rice and amazing chocolate (Sacher torte) for desert. I have not eaten such a good airplane meal in a very, very long time.

Check in etc was very good. As for on the plane, it was like flying in a freezer. It was so cold, i have flown for years and never been so cold on a plane. Staff on board said its always cold when flying which is a load of rubbish. They wouldnt put any heating on and now i have the flu because of this .

I’ve had a couple flights this week on United that were delayed by an hour or more

Should have video screens Plane audio was poor and without wired connection hard to understand crew. Should serve more than just cups of water and pretzels on six hour flight. Did not see crew rest of flight. Fix charging sockets to retain charging blocks.

My bag was lost with my medicine and I am very inconvenienced. I don’t know what happened, however I want you to do a better job on getting people’s bag back

The food that was offered based on class level of your ticket was absolutely ridiculous and disgusting. They didn't even hot tea to serve, the food was horrible. On our departure flight I was seated in premium plus economy and considering the cost of the flight the food was literally some of the worst I've ever eaten. On the return flight I sat in economy with extra leg room and was given a thin little throw "blanket" and a flimsy little pillow. The air condition was on artic and the seating arrangement wasn't really worth the money. The seat didn't recline good enough and the foot rest was laughable. Total waste.

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the locked room where it was being kept.

Do not like the feeling of being in the basic economy. Everyone should feel good no matter what.

Our original business class flight was cancelled so we not only downgraded but we were also spread out across the plane not sitting together in separate middle seats. My poor kids were scared and couldn’t see me on the flight and the crew wasn’t sensitive to the situation and what the airlines did to us. Very dissatisfied with United airlines.

The WiFi didn’t work and the seats are too close together. Very uncomfortable.

Boarding, comfort, food/drinks, entertainment and most of all an extremely courteous and friendly group of flight attendants made my 12 hour flight an absolute joy!

The bad part was 2 hour delay and we were seating in the airplane it was getting hot and uncomfortable But after they fixed the problem everything went so smooth Crew were amazing very nice polite and caring

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

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!

I paid a lot of money for seat selection and was miserable for flight duration

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.

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

They cancelled our flight the morning of departure at 4:30am.

my original flight was cancelled the previous day, and i was rescheduled onto this flight, which left much earlier in the morning, impacting my previous evening and requiring me to get up much earlier in the morning to get to the airport online. This practice happens way way way too much, and it seems on every airline, though AA is probably the worst.

The crew was very attentive and kept busy serving a variety of treats!

Offered vegetable curry when it was actually tofu which I don’t care for.

The flight was good the crew excellent…but take off delayed three hours!!!

Both mine and my husband's chairs were broken. Also it took 2 hours to get our bags after our flight which was wild.

perhaps eye contact with the cabin crew, instead of abruptness and an impatience to serve.
