I've been holding 17-18 days off with 90+ credit, weekend, holidays and other days I need off. My trips are 20-21 hrs 3 day, 29 hrs 4 day or 15 hrs 2 day, all commutable, and getting done around 6:30 on the last day. I'm bidding in the top 5% as a 5 year FO. This is all by choice. I can do this or be a CA with 12-13 days off and working weekends and holidays.
