This carry-on proved to be a great disappointment for one primary reason: it did not fit under my premium economy seat for an international flight on American Airlines. The bag was not overloaded. The problem was the result of the low profile of the seat in front of me combined with the foot rest on that seat. I suspect this may be a problem in the premium economy cabins of other airlines as well. Though the bag is made of durable materials and has sturdy zippers, it also has other design flaws: (1) there is no hard base in the interior of the bag (I added one by using the divider from another carry-on). The added rigidity is needed; (2) there are no "feet" to the bottom of the bad so when it is placed on the ground, it comes into direct contact (yuk!); (3) there is no water bottle pocket (it would have been so easy to add one to the side of the bad opposite of the one with the zippered pocket; the smaller of the two long zippered pockets along the front of the bad is pretty worthless as the capacity is minimal and the contents are difficult to access when the bag itself and the larger exterior pocket are full.
