Ooh la la! Found my favorite airplane carry-on bag. Expandable, flexible, light bag that holds half the kitchen sink while fitting under the seat, even teeny Airbus seats. Carries my 15" laptop in protector case, purse & all its contents, largest bottle of water sold at airport, 3-4 books, snacks, pair of shoes, light jacket/sweater and any last minute items/purchases. There's a decent size inside pocket with zipper for smaller items (electronics, makeup, snacks) and a large zippered pocket on the outside (for files/your clear bag of liquids). Handles are long enough for the bag to be carried on the shoulder, by hand, or looped over the handle of roller bag. Prefer this to my leather carry on bags, computer bag or back pack b/c it's lighter and more flexible.Con's:*No padding on handles*No padding in bag = no protection if bag drops.*Fits so much stuff it can be heavy to carry for long periods and can swing off your roller bag when dashing through airport*Only two pockets - one mid-size zippered pocket on inside and one large outside zippered pocket*Not the sleekest, most professional look. More fun, casual vibe, but hey, it's LeSportsac not LVuitton.*Probably not your style if you're a guy or use bags to communicate you've "arrived"Pro's:*Carries a lot of stuff while fitting under the airplane seat*Light bag*Flexible & collapsible (can squeeze into tight spaces)*Durable (have loaded down this bag on 6+ trips without any problems)*Well made tote*Easy to clean*Material & pattern does not show dirt or wear & tear easily*Fun
