Flights were delayed and due to a checked hand luggage bag by an overzealous gate agent in Berlin I missed my ground connection costing me another £80. Food was cold and bland, I honestly expect better from a national carrier operating out of one of their major hubs.

Flights were delayed and due to a checked hand luggage bag by an overzealous gate agent in Berlin I missed my ground connection costing me another £80. Food was cold and bland, I honestly expect better from a national carrier operating out of one of their major hubs.

A bit more space? Not practical, I know. I felt squished in but part of that could have been the man sitting next to me.

It was my first experience in business class. It was everything I expected and more. Service was impeccable, food was delicious and I felt rested once I arrived to London

Missed our flight to London and we were put on coach seats to Munich.

Seats were terribly uncomfortable! Couldn’t sleep! I paid for good seats when scheduled with Lufthansa, got crappy mid-section seats on Air Canada!

The seats are much too narrow and the arm rests are hard and awkwardly high, resulting in shoulder cramps. I am an average sized person ( definitely not overweight). The seats are a similar size to car seats with the added discomfort of incorporating hard plastic arm rests, that force average height individuals (I'm 5 ft 7 (f)) to hold their arms uncomfortably for several hours. The seats are much too close to the ones in front and behind making it extremely difficult to allow fellow passengers to get out, especially when the seat in front is declined. The leg room also necessitates knees banging into passengers backs for the entire flight. This used to be a quality airline who now offer mediocre service for premium cost, coupled with charging exorbitant prices for basic needs, like a seat, or luggage. Blatant and unabashed gouging of clients.

Try to humanize onboarding and take AI out. It's embarrassing and useless

I ended up buying (for $340) "extra space" seats because I my flying partner was given a STY boarding pass, leading me to conclude that she was on standby and that we had to buy seats on the flight. I later learned that the flight was not sold out and that we could have gotten on as usual. To be honest, I felt swindled.

I'm Canadian. I have the unfortunate experience of pretty not having the choice to fly with them. THEY ARE TERRIBLE.

The process overall was pretty seamless, and the crew were very friendly (especially Michael). Considering we booked expecting Lufthansa and the flight was operated by United, it was still a very good service and journey overall. The in-flight entertainment was great, with lots of quality options. One slight negative was that I had selected a vegetarian meal prior to flying, but received a vegan one. I think there should be more dietary options as it meant I missed out on some food that I would have preferred (and it seemed like the standard meals and snacks had a vegetarian option anyway). There was also a group of people who were moving around a lot and being generally disruptive at the quietest part of the flight, when the lights were off and most people were sleeping. I would have appreciated staff stepping in to encourage them to be mindful of others). Towards the end of the flight (which was very early in the morning in both time zones), the lights suddenly came on and breakfast was served. In my opinion, this was too early, and everyone was rudely awoken from sleep. After breakfast was cleared away, the lights went off again for about 45 minutes, allowing people to sleep some more. Then the lights came on again for landing. It seems like if they had served breakfast later, the lights on-lights off-lights on shenanigans could have been avoided, and people could have slept longer (and staff could have rested longer too).

Shocking. Faults with the plane in both directions which caused delays with no compensation

Very efficient boarding. Plane lready for take ooff10 minutes before time.

Great crew. Seats do not recline :( but it is budget so i should have known. Otherwise comfy leather chair. Slight slim chair but again budget so expected. No entertainment do makes journey boring. Recommend packing plenty of snacks and games or download plenty of films and music in your device. Staff excellent. Clean flight. On time.

Both of my flights had issues with their time slot with air traffic control, so they left over an hour late and the flight back to London was delayed by over an hour. Please provide more clarity about baggage requirements on booking sites, your website and within the app. I had to pay for extra bags at the airport when departing London, because they didn’t specify that your carry on bag can only be a backpack and not a trolley, my trolley bag fit the size requirements of the backpack but still I was made to pay

The crew at Check-in was very helpful. It’s was appreciate.

It’s a budget airline. You get what you pay for. They insisted on getting us out of the gate and into our slot on time. They got us to the destination safely. Aircraft was clean and well maintained. What more could we want

Half an hour delay. Squeezed into a small Departure Lounge with very few seats. Noisy flight with screaming unruly kids. Loud IPads and Phones. Heaven!

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.

Boarding and flight itself was smooth and temperature during the flight was perfect. It was just overall vibe for long distance flight, felt cheap ( comparing to KLM or TUI that I used recently). Entertainment out of date movies with poor picture quality, no games, flight map wasn't working

Basic, 737 Boeing, business class is just an economy class seat with blocked middle seat (European standard).

Unorganized, late and they lost my bag for several days.

I paid for luggage when I bought the ticket but I could not board until I paid for luggage again. The fault lays at the feet of eDreams, the company that booked our flight. Sorry, Air Serbia, but it did affect the boarding process.

Long delay (6 hour late departure, not informative enough to provide up to date info on flight, poor food quality

Plane was old. Seats were hard and very close together. No in flight entertainment.

This flight was better, plane was newer and didn’t have broken parts. Flight crew was very attentive and friendly.

Our flight was delayed from 1st July to 2nd July. But I wasnt informed! Checked my emails,every detail but I was definitely not informed! I and my family went to the airport on 1st July and learned that rhe flight is delayed to 2nd July at the airport! I am going to complain about this. I had to stay ın Kraljevo one more night. Luckily we could find a room. What ıf We couldn't?

To be honest, it was a fair flight, nothing more, nothing less. Since the route is short, I can accept poor in-flight service. The Belgrade airport is currently undergoing extensive reconstruction, which may result in some minor disruptions, but progress is expected to be made within the foreseeable future.

They didnt let me do the check in online. That was terrible cause I was coming from another country,so I had to go oit the airport and go un again through controls. They Also made me pay more for my bag which was very light. And the personal was not so nice.
