Northwest Airlines joined United and US Airways as the third airline to announce baggage policy changes for coach customers traveling within North America. Effective May 5, 2008, Northwest Airlines is implementing a $25 charge for the customer’s second checked bag. The fee is applied each way. Coach class customers may continue to check one piece of luggage free of charge.

Other changes include an increase from $80 to $100 for three or more checked bags, and an increase from $25 to $50 for overweight bags greater than 50 pounds. These policies also apply to Northwest Airlink customers flying on Mesaba, Pinnacle or Compass Airlines.  Northwest Airlines’ Silver, Gold and Platinum WorldPerks® Elite customers, SkyTeam Elite customers and passengers booked in full fare classes (Y or B) may still check two bags free of charge. Customers booked in first class can continue to check up to three bags free of charge.  For more information , visit Northwest’s online Excess Luggage FAQs.  

Is Delta next?

It's been reported that Delta will also begin charging $25 for the second bag, beginning May 1, 2008, but there has been no official statement released by the airline at the time of this entry. I'll keep you posted.
