Internet reviews on these two airlines are mostly negative. Is one less bad (inefficient, unreliable, dirty, etc) than the other?
I have flown both a couple of times. I didnt see the reviews, but I am guessing they are about things other than getting from point A to point B; which they do just fine. I guess if I had to choose it would be Tarom. The last flight on Air Bulgaria the plane was very strange. Like left over parts scrapped together. The asiles were giant wide, but the seats were the most narrow I have ever sat in. My fat "A" almost didnt fit. But for a short flight, an hour or two, its not the end of the world. Sofia and Bucharest are "interesting" airports.
