What this record means
The record shows that “NORTHWEST AIRLINES CARGO” is a cancelled Principal Register service mark, with the cancellation dated July 5 2013 because the registrant failed to file an acceptable Section 8 declaration; the owner listed is Northwest Airlines, Inc., a Minnesota corporation. The registration covered only “AIR TRANSPORTATION OF CARGO” in International Class 039, so a later use of the same or similar wording in the same cargo‑air transport context would be the closest area of concern, while uses in unrelated fields would be farther from the scope shown. The record does not give the owner control over every possible use of the words “Northwest,” “Airlines,” or “Cargo.” No Supplemental Register filing appears, and the prosecution history simply tracks the normal registration, a Section 8 renewal in 2008, and the eventual cancellation in 2013. The supplied history contains no oppositions, cancellations by a third party, or other enforcement actions. I'd treat this as a meaningful concern if you plan to use a similar name for cargo airline services.
