Freebird have operated regularly through MAN during the Winter period, mainly during the hours of darkness though so it is easy for them to pass unnoticed. Winter programmes served Istanbul Sabiha Gokcen and Antalya on behalf of RSD Travel (I used them myself during November / December). Until recently they had a flight early each Tuesday morning, though I didn't notice one this week. I suspect that series has ended with the change to Summer season. I hope their Summer ops at MAN will be seen in daylight! My flights with them were fine and operated on time.
