I purchased this bag when it still met carry on size requirements, but have only used it a couple of times for air travel since the first time. The issue for me, and I have to say that otherwise this is the absolutely most perfect bag I've ever seen, is the single handle. I got the courier bag to go with it, and the very first time I used the ozone that courier bag would not stay fixed and the bag itself flipped over on me several times while running to other sides of the airport. Nothing else would stay on the handle at all, I'm 63, have traveled the world and needed a newer lighter bag that I could carry and researched a lot before buying the osprey ozone 22". I've kept it around for years now because I just can't get rid of such a great bag. Mine has been checked twice and suffered no damage and the other three times I've actually used it were as carry on in the U. S. I just tried it again, and once again, on a simple moving walkway, not packed to the gills, it flipped when I wasn't even moving fast and my hand could not control it with the single pull. I am really sorry about this review since I really love the bag itself, but it's ruined by Osprey trying to keep the weight off it with a single pull. My thought is that the balance problems might be fixed by a regular handle as well. Now the 22" is a bit big for international carry on but I fly SouthWest here in the states and it fits just fine. That bag holds more than I could ever use for a week and is just great for up to a month easily. It is a great bag, but I will only use it for car trips from now on. It's easy to carry by the handles fully loaded. Drop the size down to a real 19" Osprey, put in a regular handle and I'll buy another one. I'd also like to see backpack straps available that snap on this style. The ozone convertible has the zip off backpack and I'd prefer a convertible that just has the one big compartment. Bag design is fantastic, handle sucks. Each use is a disappointment.
