I bought this bag for my christmas travel.  I was very pleased how much stuff I could fit into the bag!  Lots of pockets and a lot of space!  I did gate check the bag, as I had it packed as much as I could so I have not tried putting it into overhead compartments.  But if I had not overstuffed it I do not think there would be any problem.  The bag was very durable.  I would recommend this bag if you are thinking about buying it!
