I bought this for traveling on flights. I fit my Mac in the back compartment plus all it accessories in one of the middle one. My personal items in the front, Rx's on the one side, gum & candy on other side, money has it's own hiding spot with passport, a special spot for your plain ticket, another compartment for your glasses and a pouch for you drink... I think I got it all, I might be missing something... This pack has a LOT of compartments and hiding spots. I priced it at a local store and it was $20 more than Amazon. I LOVE IT!
