This is so unfair!

Effective for tickets issued on or after April 23 for travel on or after July 9, US Airways will charge an additional $5 fee to check a bag at the airport, resulting in a $20 fee for the first checked bag and a $30 fee for second checked bag. Bags checked-in online will pay $15 for their first checked bag and $25 for their second.

Delta’s and Northwest’s baggage policies are aligned. As a result, Delta’s new $50 second bag fee for international travel also applies to Northwest flights.

Effective for tickets issued May 1, 2009 for travel on or after July 7, 2009, Alaska/Horizon will charge $15 for the first checked bag.

Some airlines do not charge baggage fees and the out-of-pocket difference for a family of four traveling on an airline that charges fees could total as much as $400 if each traveler checks two bags.
