Bulgaria Air should stop using buses for boarding if possible. It is very inconvenient and delays the departure

Bulgaria Air should stop using buses for boarding if possible. It is very inconvenient and delays the departure

Easy check in. Hot snack with wine if desired. Then chocolate, tea or coffee. Altogether excellent.

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 ….

Dislike standing for 30 minutes waiting to board. Coffee disgusting, hot sandwich almost inedible. Staff cheerful. Flight early.

On time departure; arrived early into Faro. Air Malta operating flight, crew friendly and efficient.

I need assistance and I could not fault it at all. I suffer anxiety and I was always put at ease by assistance staff, and the banter was good. On board the staff was so very nice and kind and showed empathy. Thank you to them. It was my first time travelling since I lost my husband and was so grateful to them.

Food and entertainment were not available, so my rating on those items isn't actually correct. There should be a "Not relevant" or "Didn't use it" option.

Waiting outside for a long time is not really necessary

Great flight just took some time to board even when lining up early for the flight, even taking off took longer then expected.

The plane had only a few passengers, we got lucky. The crew was visibly inexperienced

The flight boarded nice and early and this meant there was no sudden rush at the gate. The only down side was the cabin was very cold 🥶

I had heard horror stories about Ryan air and was a little worried about my flights with them but I had 3 flights with them in Italy, Puglia and Sicily and it was a painless and smooth process. I was very happy.

Flying from Hamburg to Stansted was a nightmare if I have to be honest, the flight was due to leave at 15:50 and we ended up not taking off properly till 16:56. They really don’t have enough people doing the sorting of baggage where you get the sticker for your case before the security check, going through security was 10x more faster then the whole baggage situation.

The crew were excellent, smiling and kind. The seats were good for economy though my seat back got a bit sticky from getting out of the reclining position. The food was good for a Kosher meal, better than usual. Entertainment was okay, but there was no Wi-fi available the entire flight. Overall the flight was fine for an overnight flight. The flight attendant in my section was absolutely delightful.

Fortunately the departure was delayed as I had a tight connection and the incoming flight was delayed. The departure delay helped me to make my connection. Thankfully, my luggage also could be transferred in the same time. The aircraft had to be changed and the power outlet in my seat didn’t work. Again luckily as the flight was not full, I could move to a different seat where the power outlet was working.

The legroom was lacking and the entertainment system lacked adequate selection of older films. Modern films are generally not very good.

No food, no entertainment, but that's normal for short-haul flight.

The flight attendants were wonderful - one man put my carry on in the bin for me. Very attentive service. Loved the blanket and pillow waiting for me in economy. Food was excellent which is a surprise given the reputation of any airline food. Wine was fine with the meals. Delighted with the new movies - flight went by very quickly. I would definitely fly Lufthansa again.

Everything was great…Flight Attendants were specially friendly and helpful.

Catastrophic experience the gate selected customers were picked up to.pay 70 eur for overweight 1-2 kg. While some others were let to board without chcking their carry on bags. Unecessaey drama by Lufthansa that brings nothing just hating them by customers.

My flight was cancelled, but it was not Kayak's fault. Kayak did require me to pay for the ticket twice to two different venders who paid Lufthansa. Kayak/Lufthansa owes me for the first booking I made first was fraudulent on the part of the subcontracting ticket seller. There will be litigation over this issue under the current passenger protection laws.

flight was half full, plenty of empty seats, was able to lie down across 4 seats, food was good, arrived on time

Not great!!! Seats in Business class were horrible; no cushion!!!

Everything was streamlined. Timely take off. Early landing. Great flight

Low-cost airline. Airbus A-320 and 321 series are not comfortable on flights taking more than 3 hours. Seats are uncomfortable. Very limited foot space, especially when having a bag under the seat in front of you.

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.

Timely departures and arrivals. The seat was slightly forward leaning which made it uncomfortable

Flight was delayed by two hours and we then sat on the runway for another 40 minutes and circled Gatwick twice making it 3 hours later landing this is very poor compared to all the other operators I’ve flown with the outbound flight was an hour late

There were not enough staff and signage to direct people to Wizz Priority lanes for check-in and boarding. It didn't feel like we were Wizz Priority holders.

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.

Two of our boarding details were missing and they wanted to charge us 84 pounds for that, although it was totally their fault

They boarded us despite knowing we wouldn’t be taking off for another hour and boarded us into a plane who’s air conditioning was not working properly. So we were sat in a hot plane for an hour with no access to the bathroom getting hotter and hotter. A little bit of communication between the teams would have avoided this.

I planned to be working during the flight but next to and in front of me there was a family (basically all around me) who had screaming kids all the way long and they were rude and the kid was kicking me as well and constantly wanted to grab my phone etc. I was so pissed, I didn't think they will travel priority so I didn't think they'll sit next to me but they did. I asked the crew if there is a chance for me to go to another seat far away from there...And they were so kind, immediately after take off they showed a seat for me that is far away from these people. I'm so grateful for this!!! I hate that I cannot figure out these things in advance. I WOULD BE HAPPY TO PAY MORE IN ADVANCE TO MAKE SURE THERE ARE NO FAMILIES W KIDS AROUND ME!!!!

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!
