The seats were not very comfortable and very close together.

I canceled the flight but not wizz nor kayak replied to my messages. Worst experience from both

Typical wizzair flight, nothing special , but as there were flight in the evening we got sandwiches with 50% discount. Terminal wizzair is using is awful. Separate from normal airport, no duty free and only one cafe. Also was late for more than 2 hours but we didn’t got any food or water vouchers.

Had to pay £45 to check in at the airport because I didn't check-in online at least 3 hours prior... and it wasn't mentioned on the booking / App (online check-in is only marked as "included service"). Upon landing, captain failed to land the first attempt and had to take off again for an re-attempt. Overall mid experience, would definitely pay a bit more at first to avoid this again.

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

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

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.

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.

The crew was exceptionally kind. Communication in terms of gate changes could be better

There was no entertainment or food service (short flight). The flight was delayed more than an hour.

Horrible airport ever. We stood in the security check line for more than an hour. It was past boarding time and we were still waiting in line for the security check. With 2 children and a medically ill person we had a very stressful transit.

Cancelled - booked on train; and then flights started running! I spent 5 hours with 2 changes on train while flights started and is 50 min

Lufthansa has a bag policy unique to Lufthansa. We all had a small carry on and a backpack (personal item) that we carried with us through multiple other connecting flights, no problem. With Lufthansa we were charged 80 euros each for the carry on at the gate, for this one flight. When asked they said they made an announcement… problem being that we had just arrived to the gate from a connecting flight and didn’t hear an announcement. While we were standing at the counter paying the ridiculous fee several other people were stopped, while countless others boarded with the same type of luggage and were not stopped. Crazy. Good news though, when we got on the plane half of the overhead bins were empty! After an already horrible experience the lady at the counter was also terrible, so that helped round things out.

We missed our connecting flight in Frankfurt do to security and all hell ensued then.we got rebooked to Washington got there round 10 am ish didn't find out till 630 we were rerouted to United!! Then we started getting updates

The agent, who took my mother to her gate, kept talking with one of her male coworkers and treating my mother like a sack of potatoes. She was ignoring my questions because she was too busy flirting with her male colleague. This was a very unprofessional behavior. We also had to wait for close to half an hour for an agent to arrive.

Very good flight, only problem is the boarding process where some peoples do not have manners and do not how to fly ( preparing your documents, oversized carry-ons, not understanding or feigning to not understand directives).

I really like it and travel to Europe and back with Lufthansa, but it is getting expensive, a bit beyond my me

Not available crew to load the luggage for all the passengers,comon situation for local European destinations , not acceptable situation, never Lufthansa again 😉 🙄

Flight was overbooked. Crew did a great job but passengers weren’t nice and really not patient. Flying in these times is not the best idea tbh.
