The RJ vs. TP distinction regarding day trips vs. multi-day trips doesn't work at some regionals. At mine, DHC-8/200 (37 seats) crews fly the same type of multi-day trips as the RJ crews.

Here's an interesting frame of reference. We're on a 5-week bid schedule. Five weeks contain 840 hours. Our lines are built to an average of around 390 hours time away from base per bid (some as high as 430 hours TAFB). So non-commuters spend nearly half of their time away from home. You can imagine how much time away from home a commuter spends.
