You know what you get when traveling with Ryanair. I was trying to find a decent priced flight to Sofia from Brussels, and the only 'decent' option was unfortunately Ryanair. No real problem, flight had a delay of an hour while we were already on the plane, nobody told us why, so that was a bit inconvenient. I did not use any of the extra services, so I cannot comment on that. The rest van sufficient, you know what you pay for (or actually, what you don't pay for), and it the cheapest option to get a direct flight to Sofia from Belgium. Would not recommend, but might use it again.
