Are you Delta folks generally happy with PBS? I've heard many complaints from CAL folks but they have a different system I believe.

Once you receive your initial award how much flexibility do you have to drop/trade, etc. If there is adequate reserve coverage is there a limit to how much you can drop? Can you bid for stuff in open time while on reserve? Can you summarize white slips and green slips?

Just looking for a general overview of the scheduling at Delta.

Thanks!
