I have bought this backpack to travel with, I prefer a Backpack when I am getting on a plane with my little one and this backpack hasn't disappointed me. Its very roomy and has got a a lot of separate pockets and some of the pockets even have signs on the outside telling you what should be in there, its super easy to find everything and its very comfortable to wear. The only thing missing is a "mommy pocket" on the outside but since my baby doesn't use pacifiers I just use the pacifier pocket for my stuff. It fits phone, keys and other small items, however my (huge) purse doesn't fit in there and needs its own pocket - but as I said my purse is huge. You will loose an outside pocket if you also carry a big purse with you. Other than that great diaper bag
