I purchased this bag last summer for my trip to Europe. I read many comments about the bag not fitting the actual carry on dimensions (by an inch) but went with it anyway. I was traveling Norwegian Air and knew they had strict travel requirements. When I arrived at JFK my bag was well under the carry on weight and that was their focus. I'm glad I had only one bag while hopping buses and trains for those 12 days. My friends who live over there commented on how light the bag was even though I packed it with more than enough clothes for my stay. I love the easy access to my electronics/cords/books etc. pocket. I also purchased the travel cubes which made it easy to find my things without spending a lot of time looking for something.
