Interested to see this question, as I have a similar quandry this morning. I am flying to New Zealand from LAX. But will be flying on WN OAK-LAX first/after. For my return I chose a WN flight 3 hours after the scheduled arrival of NZ. Maybe that's too much time? Would 2 hours be enough--I don't know. This will be an early Sunday afternoon. So I was thinking of also booking the 2-hour-later flight--if I make it fine, if I don't I'll have my 3-hour leadtime flight. These are both Wanna Get Away fares, the others cost a whole lot more.
