Northwest Airlines says it will begin charging $25 for a second piece of luggage for flights within North America.
The charge goes into effect May 5 and applies each-way on a two-way trip. Several other carriers are adding an extra charge for a second checked bag including US Airways and United Airlines.
Northwest's high-end frequent fliers and full-fare passengers can still check two bags without paying extra. First-class passengers get three bags for free.
Northwest is also going to start charging $50 for bags over 50 pounds. The old fee was $25.
