Pretty good mix of pairing lengths. 4-days and 3-days most common. Looks like average lines are currently around 14-15 days off, built normally right at 75 hours. Not the most efficient. Lots of red eyes.
In DEN there tends to be more open time (larger base) available for swapping trips. If you don't get a commutable line, you can generally move trips around to get a commutable schedule. Sometimes, you have to fly inefficient trips or red eyes to make that happen though so it's a trade off.
