Open time is pretty plentiful if your willing to goto different bases. The larger bases like ORD and DTW always have stuff in them. Your always best to pick up a week out or they get put on reserves. 150% trips are good for people who live in base and they pick up the night before or the morning of the trip. You really have to watch it. You can fly as you want if you can fit it in rest and duty time. I personally bid so I have MAX days off together to allow myself to pick up a extra 3 day trip a month
