Next week I will be taking 8 flights on Northwest. I've never done a trip like this before so I'd like any input you may have on any part of my trip.
DTW-CRW Saab 340
CRW-ROA Saab 340
ROA-CRW Saab 340
CRW-DTW Saab 340
Would there be any way to change my last 2 flights to a different couple at the same time, with a connection in MEM instead, without a change fee?
