Northwest slashes fares to/from Detroit on nonstops

Northwest appears to be gunning for Spirit Airlines by lowering fares to/from Detroit. Our fare of the day today is Detroit for under $100 RT including tax (if booked on Northwest's site) on nonstops for travel May thru Nov. Detroit/Los Angeles is just $138 RT, Miami is $91 RT, New York (both airports) is $98 RT plus tax.

Sorry this sale only lasted a few hours!
