It all depends on you. If you live in your hub, you don't spend any time in a crashpad. If you are senior enough to hold commutable lines, then you rarely would need one, and would probably just get a hotel on occasion if needed.

But I suspect western-based pilots tend to use fewer crashpads...they are more likely to be willing to live in SEA, SFO, LAX, SLC, DEN, etc as opposed to DTW, MIN, NY, PHL...
