I want to make a trip from LSE to MSP to DCA. Using http://www.nwa.com/cgi-bin/wpmiles.cgi I put in LSE - DCA and it said my roundtrip non elite miles would be 1,630. I thought that was a bit light so I put in LSE-MSP and then MSP-DCA. The first leg was 1,000 miles and the second 1,862. How would NW really figure this flight.
Also, anyone seen any good deals for this flight for the last two weeks of OCt. My dates can be very flexible but would like a Thursday-Monday.
