1. If you're looking to maximize segments, lots of the discussion in these might be germane or adaptable:

2. If you haven't already done so, check Travelocity's Dream Maps.

3. Do you have to do a one day run, can you overnight, can you do a Saturday night stay? All might make a difference.

4. There seem to be lots of $198 east coast fares right now (at least when I checked a few days ago).
