Seats are quite small, but due to the plane being empty we were aloud to switch seats to have more room

The water was handed out as we were entering the plane, instead of when we are set down and our hands are free of luggage. There was absolutely no food offered from Sofia to London, except a low quality chocolate, which was not delicious. The flight between London and Miami was ok, as far as service and food, but it was absolutely freezing, throughout the whole aircraft, especially in the back seats, I had to cover my head with a scarf, besides using the blanket and still I was feeling extremely uncomfortable. The passengers seating around me shared the same opinion. We did ask for something to be done about it. The gentleman did try to adjust it, but the effect last very short time, and towards the end of the flight it was extremely cold and blowing strong again ….

Cons: "Staff seemed confused and would not let us seat at our assigned seats which we picked in order to accommodate our baby. Instead they put us in an even worse spot and decided to ignore the people that took out seats and left them be."
Cons: "Them actually refunding my flight when I couldn't legally travel due to COVID lockdowns."
Pros: "Nothing"
Cons: "To add food and to patk the plane at the linkway"
Pros: "It was a direct flight to my destination"
Cons: "Check-in took 1 hour and 30 mins. Single Check in desk for economy and business, long line. Flight went late by 50 mins on departure"
Cons: "I wanted to note that while screaming at gate D1 the stuff was beyond horrible. Lazy to talk, a lady who was on the screaming machine kept making nasty comments, really inappropriate addressing foreigners and people who speak Bulgarian. I found it highly disturbing, border line harassing. You can’t work customer service and be such a nasty grumpy person. Everywhere in the world that attitude won’t be allowed, or sanctions must apply. The lady who was collecting money for the checked bag was extremely rude and lazy. Almost kicked me out for not paying for my checked bag online. Excuse me? Why is she there then? The flight was fine. However, the flight attendance slipped the last 2 rows with drinks. Please make sure that the people who work at Sofia airport get some kind of basic human training. Unfortunately, they do not wish to make you feel welcomed or cared for."
Pros: "fast trip, clean plane"
Cons: "Was a bit different to get on a bus to take you to the actual plane"
Pros: "Nothing. Bulgarian Airlines is a fifth world company!"
Cons: "Everything! The flight from Sofia (after flying in a plane that looked like a bus from the 80s), was late over two hours. Bulgarian airlines lied to us in Sofia that we would be rerouted on other airlines and find out our new tickets only at transfer desks in milan. There were NO transfer desks"

Another 35 min delay landing No apology no communication or acknowledgment about this

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

Hated every minute of it. Delayed for over 10 hours only to have to cancel rental car, car insurance and hotel. Its taken me 3days to get to my final destination when it should have only taken 12-14 hours. Very unhappy with Lufthansa.

Overall good experience. Polite crew. Good foodandentertainment. Seats are small and bit congested though.

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.

All flights cancelled with no way to reach the airline

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).

United flight from Frankfurt to Istanbul is on Lufthanza and United could neither provide a boarding pass or Lufthanza code to get a boarding pass. Very poor connection ability in Frankfurt and much frustration with the connection.

You only get a chocolate square and small bottle of water.!

Pierwszy raz odbyłam tak pozytywny lot. Uprzejma, świetna załoga. Kapitana lotu W6 1771 z 6.01.2024, pozytywnie zaskoczył wyraźnym kontaktem i ciekawostkami na temat lotu, jak i informacja o zorzy polarnej zachęcając do zobaczenia przez okana. Delikatne perfekcyjne ladowanie WIELKI SZACUN i GRATULACJE dla KAPITANA!!👏👏👏

After the flight. Waiting to long to get off the plane

Very very very…… uncomfortable seats /does nor reclain/ and so little space /this was 5:30 hours flight- and quite expensive no longer low cost airline/ 5:30 hours flight and no water or snacks was offered anly very expensive sales.

Was denied to enter the previous plane so couldnt make it to this one

Got rejected to enter the plane because i took calming pills. Im scared of flying and i always take it since 12 years and it was never a problem with other airlines.

Shambolic boarding with ZERO information on why there was a delay. Don't treat customers like sheep. Crew good. Aircraft new. Late departure with minimal information from flight deck.

The flight was 1.30 hour late because of the Police checking 4 passengers. This was not Ryanair fault but was quite ennoying.

The boarding process was fast Uncomfortable seats ,do not recline.

My fligh was suddenly canceled and no ine approached me The web response was the only one and it was poor and not satisfactory Wizz did not take care for moving me and my family to another flight instead and simply gave us back the flight credits which i cant do nothing with !!

The crew was not very friendly or did not seem like very approachable. The plane was quite dirty and it didn’t sound too good when landing.

Better food and more space in the seats. Also when doing the web check in both times I was going in to your site the minute you open it and there is not really many seats to choose only to buy!!!

It was ok, not as good as it used to be. The Heathrow connection was a disaster - complete anarchy, unknowledgable and skimpy assistance and signage. Gate crew at next flight was great, held the flight while my wife struggled through security.

It was great! The seats were comfortable, and they fed me during the transatlantic flight, something which I have been missing out on for the past 3 years as I travel to and from school.

The seats were uncomfortable. It was an old plane. The crew could have been more hospitable.

This flight was cancelled at the last minute. We were rebooked on another flight but a day later. We lost a day of our vacation and paid for a night in a hotel we couldn’t use. The flights we were rebooked on (both American) messed up our seating on both flights-we didn’t get the seats we had paid for. All in all, a terrible experience.

I declined a wheelchair in Vienna as I was told it was a short walk. However, though I "boarded" the bus first, I was at the back when we got to the plane. There were steps up to the plane and no-one helped except the stewardess as I was near the top of the stairs. She found a better seat for me also.

Horrible connection in Heathrow on flight to destination. Flight missed due to delay on incoming flight. They did rebook us, and then that flight was delayed 2 hours. They don’t post gate info until 45 minutes to departure time which can cut it close if you have to take a tram to your terminal gate area. Then our return flight was completely cancelled. They notified us at 4:30AM. They rebooked us on a different airline and a different fare class. We were completely screwed. Travel day ended up being 30 hours. I will never fly them again.

Lost our bags in Heathrow, We didn’t receive bags in Mallorca for 3 days, out of a 7 day cycling vacation. Really inconvenient and disappointing!

There's no inflight entertainment, plane was old, power USB didn't work

We missed the flight to Barcelona because the flight from Baltimore was delayed. We flew on Vueling VW6653. Our luggage didn’t arrive. Please help us get our luggage. We are staying at Hotel Gran Via in Barcelona
