Here are TWO personal item bags, that will fit under the seat of almost any airline... but not only that, you have 3 ways to carry them (handle, crossbody, and backpack) or use the trolly passthrough and let your carry-on do all the work! These bags can even be used when you are not traveling and both have a padded computer compartment, so they are useful all of the time!
