I used to have the Aliza 24 for traveling. After it got stolen, I replaced it with the carryall. I'm petite (5'2"), so the carryall is perfect for me. Plus, it has pockets on both ends of the bag. I also purchased an a non-leather strap from LV for the bag so I can wear it messenger-style or over the shoulder.
If you get the keepall though, I recommend getting the mon monogram!!
Happy shopping!
