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."
Pros: "Nothing"
Cons: "To add food and to patk the plane at the linkway"
Pros: "It was a direct flight to my destination"
Cons: "Check-in took 1 hour and 30 mins. Single Check in desk for economy and business, long line. Flight went late by 50 mins on departure"
Cons: "I wanted to note that while screaming at gate D1 the stuff was beyond horrible. Lazy to talk, a lady who was on the screaming machine kept making nasty comments, really inappropriate addressing foreigners and people who speak Bulgarian. I found it highly disturbing, border line harassing. You can’t work customer service and be such a nasty grumpy person. Everywhere in the world that attitude won’t be allowed, or sanctions must apply. The lady who was collecting money for the checked bag was extremely rude and lazy. Almost kicked me out for not paying for my checked bag online. Excuse me? Why is she there then? The flight was fine. However, the flight attendance slipped the last 2 rows with drinks. Please make sure that the people who work at Sofia airport get some kind of basic human training. Unfortunately, they do not wish to make you feel welcomed or cared for."
Pros: "fast trip, clean plane"
Cons: "Was a bit different to get on a bus to take you to the actual plane"
Pros: "Nothing. Bulgarian Airlines is a fifth world company!"
Cons: "Everything! The flight from Sofia (after flying in a plane that looked like a bus from the 80s), was late over two hours. Bulgarian airlines lied to us in Sofia that we would be rerouted on other airlines and find out our new tickets only at transfer desks in milan. There were NO transfer desks"
