I am considering a change to my luggage plans and one item I'm pondering is the personal carry on item. For US travel on a typical plane this means an item that can fit under the seat in front of you. For the main carry on item I usually go for something around the size of the Aeronaut. The personal carry on is normally a backpack for me.
I've found that you can fit a pretty big backpack under the seat in front of you in most cases. I have one for a laptop that is huge yet still fits. I also have a small Kata backpack that fits easily but doesn't hold much. The Kata is my preferred carry on lately because it's protects the camera very well. But I would like more room so I'm thinking of trying something else.
Anyway, just thought I'd ask to see what others do for their personal carry on item.
