I needed something to carry a computer, textbook and odds and ends that would fit under an airline seat. It was more than adequate and fit nicely under the middle and window seats with room to spare for my purse. Not sure how it will fit under the seat of a smaller airplane, but it may be fine. The quality seems good for the price, the wheels and zippers worked well. The handle stays up as long as there is no pressure on it but it was not a problem. It is lightweight and got the job done.
