Terrible! Been flying twice with them. Huge delays. Almost 33 years old aircraft... Taxied on the tarmac for one hour with AC turned off. 38c temp outside, almost 50 inside. Flight attendants unpolite, are not answering any questions. No safety rules shown... During push back, AC still turned off. Burning smell coming out... Started to work after one hour of the flight. Why? Saving fuel?
Broken lavatory handles, paint coming out from the walls, 1 of 3 lavatories not working. The aircraft is an old crap. Should be written off, like the whole airline!!!

Worst airline I’ve flown yet. The flight was 2 hours late but we were never notified it was running late. We spent over an hour in the gate hallway with no word from the staff. The plane was the oldest plane I’ve seen.

4 flights for 5 days - 5 hours delays all together with not even one flight on time. No answer from anyone about delays. My paid seats changed just before flight without any reason. The only way to receive compensation is true court, the company is refusing anything else. It is really worse than all low cost companies.
Just do not do it!

They cancelled two flights and when you try to contact them by phone nobody ever picks up - typical for Bulgarian institutions in general, their staff is probably on a 4 hour lunch break as usual. Then when you email they reply with impersonal useless info that's of no help. And that's the "national carrier"...

This happened to me more than a year ago but I am writing this now as I wanted to know how my legal case against Bulgaria Air would end.

In brief, they canceled my flight without letting me know. Worse, the previous night the flight was still announced on their website. I found out about the cancellation two hours before the flight at the airport. At the information desk, I was told the flight had been canceled "A LONG TIME AGO"!!

It took Bulgaria Air a pretty long time to pay me back my ticket. When I asked them about the due compensation, they did not bother to answer. I hired legal support who tried to reason with them. In vain. Bulgaria Air refused to pay up. Then, we took them to court. Almost a year passed by, and we won (Bulgaria Air lost, of course), and they finally paid the due compensation, which is nothing considering the hassle.

If you don't want that to happen to you, think twice before booking with them.
