We continued to do them at AirTran after part 117, but as
@ZapBrannigan mentioned, that all came to an end as the Southwest merger progressed, because their software was incapable of scheduling them.
They always went super senior for us. I was top 25% in seat, and I struggled to hold them some months. My years flying CDOs were the best of my career. Flying with the same small group of pilots and FAs who always bid them, home every single day, flying only about 200 hours a year. It was fantastic. A part time job that paid a full time salary and every day at home.
