I think the original poster meant if he credited the Delta flight to his NWA account. Like said above I don't think nwa would look @ delta passenger list. 2 things you could do.
1. Once you arrive @ the airport change the return flight to a Delta FF #
2. Book the return flight for when your are in BOS and check in on line and don't show up. If ever questions you got to the airport late and missed the flight and drive with a friend instead. You could even do that from home.
I think if you just don't even do anything with the return flight it wouldn't be a problem.
