7 On Your Side's looked into how bad it is.
Delta and Continental Airlines are the latest airlines to raise their baggage fees.
Both will start charging $25 for the first checked bag and $35 dollars for the second. U.S. Airways had already raised its baggage fees to the same amounts back in August.
Contributing Travelocity editor Jennifer Gaines talks about what is behind the fee hikes.
"The airlines are struggling and this is another way for them to generate revenue. These baggage fees have actually been proven to be gold mines for airlines. Last year alone in the first three quarters alone, they earned more than $2 billion, just on baggage fees alone," says Gaines.
The new baggage fees take effect on Wednesday on Delta, Saturday on Continental.
