I flew Flybondi a couple times mainly because the schedule was much better for the route, and it was more convenient to fly out of El Palomar than EZE. Of course, it was cheaper as well.
It wasn't as bad as I expected. I read they had a couple of incidents, but not sure they had more than any other airline.
Competition is usually good, shame that it's going under. They asked at the end of flights how many people were flying for the first time and many hands would go up.
Aerolineas and their unions, the bus companies and probably other special interests were threatened by Flybondi.
