I didn't know Northwest had boxes available.</font>
A couple of years ago I was given one such box because my lone suitcase was about 20 pounds over the limit. Although it was free, I was told NW would not be responsible for damage to its contents as it was "not suitable" for purpose of checked luggage and thus likely to be damaged.
