Try using the "multiple destinations" sections of the search engines.Input logical connections. Assume that you can travel 150% of the non-stop distance. For instance, EWR-SEA(~2400 miles OW) can be done EWR-IAH-SEA on CO- ~3300 miles). About a month ago I got a $400 RT by playing with this on NW as follows: EWR-DTW-IAH-MSP-IAH-SEA. Note that this cannot be done on the return becasue ofthe time differences.
