Everyone should be allowed to have only one carry on so every one gets a space for their carry on in the over head compartment. It is not fair that I don't get to put my only carry on in the over head compartment due to no space. lots of people had at least two and even three. I also paid $30.00 for luggage and then I don't get to use the overhead compartment because the others have more than one. It is not fair!!
