There were only 2 toilets and one of them did not work in business class. We are not allowed to cross classes so had to wait in line to use the toilets!! The entertainment touch display was finicky and did not work all the time.

Layover time was not sufficient as the gate was too far, I had to literally run and was out of my breath. This was main drawback. The crew was wonderful and so is their service. I loved interacting with them.
They didn’t have my special meal I requested. It seemed like they just put a sticker on a veg meal for me. I had a little bit of it but it didn’t taste good and I got sick from eating it by the time I boarded my Frankfurt to NY flight
I tried both on line and by calling the Customer Service line to arrange for a special meal as i have food intolerances. I was under the impression from your service representative that I was successful. I was not. I cannot eat spicy foods and get very ill if i eat bell peppers. I could not eat either menu choice and no special meal was actually ordered. ( your representative tried to order it for a flight that did not have meal service!!! - found this out later). Your wonderful cabin crew managed to put together a fruit, salad, roll and cheese tray for me so I had something to eat. WHY WOULD YOU SERVE SPICY FOOD, WITH NO MILDER OPTION,ON AN INTERNATIONAL FLIGHT???
boarding and flight very smooth. Crew very friendly and efficiant. Everything worked well
Flight attendant was very rude helping me out. Food was discussing did not eat any of it.
Crew was professional and great, flight was clean. However food was pathetic. I ordered a Hindu meal assuming no meat but they served chicken. Need to be very specific- Hindu meal should be categorize as Vegetarian - no meat or egg. Or it should be specific that we are serving meat.
Late flight Delays Poor service Poor staff Worst airline ever
From HYD to FRA - plane (787-9) seating in economy was so terribly cramped. There were tons of empty seats but we were ordered (by Lufthansa's crew) that we cannot change seats even after we reached cruising altitude, ostensibly because of "safety reasons". So what could've been a nicer experience was totally soured. Food was good. Flight was punctual. From FRA to LHR - for some strange reason ("totally full flight") they asked us to check in our cabin bag! We told them that there were medicines and delicate items inside al we'd like to keep it with us in the cabin. Then they VERY rudely *ordered* is to unload our delicate items and meds and the. Check in the bag. We complied. On the way into the plane we saw many others (whites, of course!) rolling in similar bags happily into the plane. This, this leg of the trip was completely ruined for us by Lufthansa's crew. Bottom line: I am never traveling Lufthansa again!
it was great the cabin crew were polite and detail oriented.
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!
