the glutenfree food was not more than ok. oatmel is not considererd 100% glutenfree, which you served me. I would expect a better meal

Checking in and crew were great. Seats in front of you in economy recline so much that you can't get out of your seat. I guess thats why its economy....

Flight was on time. Could have been a little more comfortable. Baby cried all night.

The flight attendants are amazing. The plane itself was not in good shape for passenger comfort. A good share of seat reclines were broken so they went back an unlimited amount, which meant the person in front of me was fully in my lap (the crew helped me find another seat but that would not have been possible on a full flight). Moisture from the ventilation was also dripping on me. And the entertainment system is almost impossible to hear.

Bad experience overall. Crew did not provide food for our 2 year old (even though we specifically bought a child infant seat for her and literally bought another full price flight), which was unacceptable. And we had to pay $310 each way to carry our ski equipment even though they advertise it as something that is free. Tickets were purchased the same way as usual, but they told us we had Economy Light tickets (I never elected to have such seats). Just plain manipulation and false advertisment. Very disappointed overall about this airline.

Poor. Seats uncomfortable. No leg room. Hot and humid the whole trip. Food and staffs were ok.

Flight was cancelled due to technical problems with the aircraft. It would be nice if SWISS would invest in new aircraft; that would for sure minimize the technical issues with (old) aircrafts.

So disappointed, the flight from Zurich to Sarajevo was delayed for two hours for no reason, they were also shifting gate several times prior taking off

Overall a good experience, the flight was on time, the crew very attentive and friendly. However the seats are too cramped, there is no space, and as soon as the person in front reclines the seat, it's literally in your face.

Bag lost. Lost bag recovery process is an unsatisfying customer experience. Because 1) bag is still lost but also 2) the process is outdated and form-heavy and 3) in our case also involved a long line.

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.

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.

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!

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.

Seats are very small and uncomfortable so such a long flight. My tray table was broken and taped up. Flight attendant untaped it to put my tray on. I taped it back up when done. The armrest between seats was broken and metal exposed. I will not book Air Serbia again.

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.

Very poor embarkation in Belgrade , employees not friendly, not well organized. The flight was delayed by over 2.5 hours and the employees at the air Serbia desk at Belgrade were unhelpful, disinterested and all appeared more concerned about their snack (all were munching something) than assisting passengers
