Granted - my "evidence" for this is not professional but an imho decent knowloedge of the Turkish airline market. We had that many incidents, rumours and "press scandals" (press making a scandal of nothing) here in GER about TC-airlines that I started researching a bit more than usual about them just our of curiosity.
For the record: Saga has NO whatsoever negative record such as ban from EU airspace etc. I have NOT flown on one of their aircrafts.
However, their rep among qualified ground staff, ATC etc. here is not rpt not one of the best. And when I mean "qualified" staff, I do not mean passenger internet forums and such.
