The two zipper pockets on the front are sized to take my passport and a few credit cards. There is an inside pocket for my kindle and a loop to hook onto the seat back tray holder thingy.
The inside was fun because I had already made a pocket for the kindle and THEN I decided to line it. Lots of hand sewing, but I think it looks OK though it wouldn't win any awards. It is functional and I think it will be useful.
