whole story on it this morning: http://www.startribune.com/stories/535/4832654.html

NW has 101 gates in the lindbergh terminal, 11 airlines use the remaining 16 gates.

AA-ORD,MIA,DFW,STL
UA-ORD,DEN,IAD
AC-YYZ (handled by UA)
F9-DEN,LAX
FL-ATL,MCO
CO-EWR,IAH,CLE
DL-ATL,CVG,SLC,DFW
ATA-MDW
US-PIT,PHL,CLT

At C:
AW-PHX,LAS

Nah, that's not a lot.
