The food from Delhi to Frankfurt went bad or something cause I got sick after I ate the meal and felt ill the rest of my travel back to NY

Paid for exit row at the back of the plane. Window seat with lots of leg space. Food was inedible (as usual). Brought my own.

Boarding procedure should have the crew and personnel who are more trained, in a sense of precisely knowing what can be done and what cannot. They do not have the exact information on what you should do in the first place, also the boarding itself was slightly delayed due to the aircraft "not being ready".

love the crews and my only problem was the delay at Frankfurt was very bad. I have travelled with Lufthansa for over 30 years now and this was cost me some planned business appointment

..it was short.. I didn't like that my red bag went out completely stained with black stains..That's probably some airport staff bad handling but still

Efficiency of staff, and comfort and cleanliness of aircraft was all great. Maybe a hot drink without payment at that time in the morning would be good!

Both flights were delayed over 1 hour. And I had to pay for seats, even though my reservation supposedly included free seat selection.

Late departing Budapest, very stressful change in Munich though we made it since connecting flight was delayed.

The plane was late (as was my flight out from Birmingham the day before)

The crew was fantastic. They were always there when we needed them. No wifi on an 11 hour flight was a bummer. The entertainment onboard was boring.

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!

Were delayed in the airport for 5 hours with no explanation. Flight kept getting delayed by an hour at a time and wizz air staff were no where to be found

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).

Entertainment is nonexistent. Food might have been good, however due to language barriers I didn’t get to have any food. Flat bed seats and layout was excellent. Crew efficient and straightforward, but lacking any western style approach. Not that I’d expect anything else, but one could have hoped.

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

Flight took very long to even get checked in for, everything was late and written out by hand. My luggage was lost for several days and it was the most unorganized flight experience of my life.

Delaying more than 5 hours from Belgrade to Tirana Information very rude to questions

It's the shortest trip one could get from BEG anywhere, so it was fine.

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.

They had lost my ticket and despite showing them the confirmation email with the itinerary and receipt of payment for the flight they could not put me on that flight and rescheduled departure postponing it by a whole week

Kraljevo is very convenient airport. It's brand new, small.and efficient. Great job!
