What this record means
The record shows that “SOUTHERN AIRLINES” is an abandoned service‑mark application; the owner listed is Northwest Airlines, Inc., a Minnesota corporation, and the filing was abandoned on June 3 1998 because no Statement of Use or extension was filed after the Notice of Allowance. The only goods covered were “air transportation services” in International Class 039, so a later use of a similar name in the airline or air‑transport sector would be the closest area of concern. The record does not give the owner control over every use of the words “Southern” or “Airlines” in unrelated fields. Because the mark was never entered on the Supplemental Register, there is no supplemental‑register sequence to explain. The latest meaningful event is the abandonment entry on June 3 1998, and the supplied history shows no oppositions, cancellations or other enforcement activity. I'd treat this as a moderate concern if you plan to use a comparable name for airline‑related services.
