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 ….

I paid for priority (2 bags) and because I had 2 backpacks the boarding crew jumped to the conclusion that I had a non-priority ticket and had one bag too many. The person who spoke to me was quite rude and told me to leave the line without looking at my boarding pass that I was trying to show him. I queued to have my bag sizes checked - neither of them are oversized, in fact, either of them can fit under the seat in front of me but I paid for priority because I wanted to bring two. In the end, the same person had to speak to me and then said "you have two bags" to which I replied I had paid for them and when he checked my boarding pass he did not even apologize for the trouble.

I didn't eat any food so can't comment on that. The prices on the plane are extortionate (as are all prices on planes). Everything else was seemless and a great experience

Nothing unexpected considering it is a Ryanair flight. It does the job. Nothing above, at all.

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

This was the worst boarding ever. We were kept in the boarding bus for almost 40 minutes without any information or update. Very uncomfortable beings squished with another 50 people and not knowing what was happening.

Their customer service needs an overhaul. I wish we could access them and the could be more helpful. Also, the website has been crashing and I had numerous technical errors. My flight was cancelled and we spent so much time trying to get help because the tech was failing.

The system of checkin by online only not good at all.. Because not everyone knows how to to do it and when the people go the airport without checking online it charge him, this really unfair 55 Euro this too much for nothing.. Thanks

It is what you pay for. Always delayed. Very small planes. Hard to fly with kids.

Good, everything went straight forward and on time, I am satisfied

bring iPad for entertainment. The flight was punctual as most of the time.

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.

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 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.

All in all is not bad, but the boarding by walking outside in the airport airplanes area in the wind and rain to go up the stairs to board the plane that’s too much inconvenient. Hopefully that will change and we use the normal gates at the airport to board the plane! Thank you!

The flight was delayed again. I had a bad experience with Wizz Air, and I don't want to travel with them again.

After the flight. Waiting to long to get off the plane

The boarding process was fast Uncomfortable seats ,do not recline.

The crew was not very friendly or did not seem like very approachable. The plane was quite dirty and it didn’t sound too good when landing.

Economical flight. Good for the price. Direct destination, no stopovers. No USB ports for mobile charging. No movies or tv onboard.

Very aggressive clerk at the boarding gate. Forcing people to pay for baggage’s that actually fit into their small cage
