Thanks for everyone's assistance.
Is it possible to combine the Northwest Worldperks miles with the miles I obtain through sites like Milesource.com?
I checked my Worldperks miles and I see my balance is 10,000 miles (I don't recall getting that many miles but I won't argue). Is it feasible for me to obtain the additional 35,000 miles in 8 months for a free ticket?
