Airline charges passengers for use of overhead compartment

CNN:

Spirit Airlines announced Tuesday that it will charge its customers $20 to $45 for items they place in the overhead bins. 

Each passenger will still able to bring one personal item that fits under a seat for free, such as a purse, briefcase, backpack or laptop computer. They also won't have to pay extra for items such as diaper bags, pet containers and cameras.

I don't like the sound of this.  Hefty fees for additional checked bags created the problem.
