In addition to up-posts' links, there are a few threads on xDONEx out of AMM. Don't have the links off-hand. Search tool will produce some good results, I hope.
The hard way, but a great learning process, is to stitch together your own itinerary (or based on someone else's itin found around here in OW forum) and find out for sure. OW has great tools for that. Go to
