I haven't done this a lot but here's what I did for my SEA-TPA run in early December. I went to Dream Maps on Travelocity and asked for any flight under $200 leaving from SEA. I then clicked on a couple of destinations until I found a NWA flight. It happened to be $198 SEA-TPA. However, when I checked the rules on this flight, I found that I could only travel on like Tue, Wed, and Sun. Well, I was looking to do this over a Saturday night--not use up my remaining vacation days. So, I investigated further on this run and found a fare I could do over a Saturday night for $224. Since I had an NWA e-cert for $25, I got the price down to $199.
Many miles for just a little money. If I were interested in NWA miles, this would be a double mileage run because you can connect through Memphis which is a bonus route right now. Since I am flying under my AS number, I will still get bonus miles due to my Gold status with them plus more qualifying miles if I can upgrade any of the legs.
I hope this helped and addressed your question. There are many others here with way more expertise than me, and I hope they will chime in here.
See what I mean about the experts--tvl4free posted a minute before me which means we were typing at the same time!!
