Fully commutable lines are hit or miss in Denver depending on the month. I've been here a little under two years, about half way up the seniority list in DEN, and if I work weekends I can hold mostly commutable lines. Between line bids and trading with open time I have no trouble making my schedule commutable every week. Now, if you get pickier and want weekends off, efficient trips, no red eyes, etc, that is a lot more difficult. Overall, I have decent amount of control over my schedule, but I fly red eyes and inefficient trips (low pay for 3-4 days of work) to have that flexibility
