Airlines are raising fees again, this time it's for checked bags. American and Delta have recently joined US Airways, United and Continental in raising fees for checked baggage.
Each of these airlines are now charging $20 for the first bag and $30 for the second bag checked at the airport. Some of them offer a $5 discount for checking your bags in online.
Alaska and Hawaiian Airlines are still charging $15 for the first bag and $25 for the second.
Southwest Airlines is still allowing checked bags for free.
