Last time, I found that my plane went from DTW-LAS-PHX-OKC-PHX and then my flight from PHX-SEA.
Yes, for me the easiest way is to have a hard copy of the WN schedule. It is usually pretty easy to find the flight either using the flight number for a incoming flight if it is a continuation or the arrival time of an incoming flight if it is not.
