Starting today United Airlines will start charging most of its customers $25 to check a second bag. Currently there are seven airlines charging this fee Continental Airlines, Delta, ExpressJet, Northwest, Skywest, United Airlines, and US Airways. The list will soon grow by two when American Airlines start charging $25 on May 12, and Jetblue starts charging $20 on June first.
The airlines said the business decision is tied to offset extra fuel costs.
