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 ….

Cons: "Staff seemed confused and would not let us seat at our assigned seats which we picked in order to accommodate our baby. Instead they put us in an even worse spot and decided to ignore the people that took out seats and left them be."
Cons: "Them actually refunding my flight when I couldn't legally travel due to COVID lockdowns."

A delay of almost 3 hours. It was evident that the staff wanted us to board urgently, to the point of rudeness, to avoid paying compensation

They boarded us but somehow did not manage to record us boarding, so rather than check if we were onboard they removed our bags from the aircraft. I got a call from Ryanair staff in Dublin when I landed in Madiera asking me where I was!!! When I said I was in Madiera I was told what had happened. Our bags were to be sent to Madiera the next day via Manchester, they didn’t arrive. They are now due to arrive two days before we leave. I don’t see myself using Ryanair again unless I am forced to and even then I may just refuse.

It was appalling, full of young people who were drunk and disobeying instructions to sit down. Crew did nothing to enforce. There was a Ryanair pilot sitting in the aisle opposite me who talked through out the safety briefing so loudly I couldn’t hear. Whole thing felt unsafe

Delayed for 2 hours lack of communication no refreshments as promised and the drinks on board were not as ordered and refused to refund

Flight was over an hour late. Boarding was really messy with long queues at the plane.

I couldn’t understand the aircraft tannoy announcements I was in seat 20C - nobody in our row could either. Speakers a bit too quiet plus messages read out too fast. Otherwise excellent flight. (Flight delayed by 50 mins)

Unnecessarily delayed and remarkably inefficient boarding contributed to a significantly delayed departure. Seats/legroom astonishingly uncomfortable even by Ryanair standards (minimal legroom plus reinforced plastic seat backs ensure you get punched hard in the knees every time the person in front moves, and as a 6-foot passenger I had nowhere else to put my legs. Upon late arrival at the gate in Luton we were kept waiting another 20 minutes before being allowed off the plane. Both Easyjet and Wizzair are currently a better bet.

The lady at the boarding gate was so rude. She was challenging people being in priority and looking them up and down as if they weren’t dressed for first class. This was Ryan air priority. We all sit in the same seats. She loudly called out to embarrass a man who she believed had cheated and got in the priority line. He had a valid priority ticket and even worked for Ryanair. Also challenging visas insisting people download them until they proved on the government website it wasn’t required to print. The Ryanair employee who was challenged said she is always like this. She also pulled people from regular boarding as they were fashionably dressed and upgraded them to priority and changed their seats. That was comical. I think she felt she should be working for Emirates first class, although they would t have stood for her rude behaviour

The punctuality of f the flight was super: we left on time and arrived about 20 minutes early - and the cabin crew were both friendly and efficient. The only downside was that Ryanair appears to have resumes its old obsession with sizing cabin bags again after a long and welcome absence.

They lost a bag and now our vacation is ruined

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!!!!

Brand new aircraft Airbus 321neo, good seats although no recline (so no arguments with other passengers). Orderly boarding using front and rear aircraft doors for efficiency. Departed on time and artived 25min early. During check in, ground staff are very strict about permitted baggage and carry-on weight and size - you're only allowed what you paid for. Onboard food and beverage prices are a bit high but similar to airport coffee shops.

Boarding was fine, crew professional but not very friendly. Seats are very tight & uncomfortable. 1h delay due to crew change and mechanical issues - no communication whats going on.

Crews are great, chill, good snack sets on offer, I didn't feel they play any annoying budget airline games. I will probably fly with Wizz every chance I get it

If you don't want to pay a lot at check in desk, you need to use online check in tool, but you still need to go to check in desk to have it printed out. Then what's the meaning of "online check in"? Extra security check, as if 9/11 just happened!

After adding baggage costs, and considering the necessity to re-checkin at each stop, and the €50 I was tricked out of for the ridiculous 3 hour min check in, I’ll never fly this very hungry Hungarian airline again!

This airline is routinely voted the worse airline in Europe for good reason. If you have an option, just avoid them.

Everything was great until it came time to pick up our luggage. We arrived in orly airport terminal 1, our luggage arrived in terminal 2. No signs to tell us, we waited for almost an hour before someone figured it out.

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!

Long delay (6 hour late departure, not informative enough to provide up to date info on flight, poor food quality

Plane was late causing me to miss connection. Flight the next late causing me to miss the rebooked connection. Air seberia I think is more late than on time

Plane was old. Seats were hard and very close together. No in flight entertainment.

This was my connection flight that was moved time ahead for a almost entire day so I lost it and I had to purchase new ticket once I landed in Copenhagen since nobody wanted to take responsibility for moving flight in that way so it’s impossible to make it. Very poor job by Underpricer, Air Serbia and SAS.

I purchased an exit row seat and priority boarding, about 3 months in advance. Without any communication whatsoever, my seat was moved to row 2, when I checked my reservation 2-3 days before departure. As no exit row seats were available anymore, I selected a seat 1C. However, once at the airport, I was issued maybe the worst possible seat, 29E, middle seat, one row before the last. It is not worth my time to request the refund on the ancillary purchase, I am simply done flying with Air Serbia. Also there was no boarding process to speak of at all, or online check in.
