The Travelpro Bold 22" Rollaboard measurements are right at the maximum allowable carry-on dimensions I have seen for many airlines. The Bold 22" Rollaboard will give you the most storage space you can get with a carry-on.When it comes to luggage, I tend to prefer the 2-wheel upright versions to the 4-wheel spinner versions. For me, the two wheels are more protected, and less likely to get snapped off or damaged during travel and baggage handling. 2-wheel upright luggage will also tend to be more stable on lightly sloped surfaces. I have never had any issues with maneuverability with my previous 2-wheel upright luggage.The Bold 22" Rollaboard sits perfectly vertical and is very stable when resting on the wheels and bottom support bar. As long as the weight of the items loaded inside the carry-on are reasonably balanced front-to-back, there should not be any issues with the carry-on tipping over in either direction. However, if you hang a purse or other luggage over the handles that extends over the front of the Bold carry-on, you may run into stability issues depending on how heavy that purse/luggage is (the same would be true when using a spinner-style carry-on).The Travelpro Bold 22" Rollaboard frame is solidly constructed. There are three rugged, securely attached cloth handles positioned in convenient locations for lifting.The Bold 22" is lighter than my smaller Eagle Creek carry-on that it is replacing. The aluminum pull-out handle feels like it may not be quite as sturdy as my much older luggage, but it could just be that lighter and still sturdy materials have been developed over the last 20 years. The pull-out handle has a zippered cover for protection, and I will be sure to zip this up if I need to hand the carry-on to the baggage handlers at the gate.There are two zipper styles:- There is one sturdier style zipper that has thicker pull tabs and the metal hoops for TSA locks.- The rest of the zippers have smaller teeth and smaller pull tabs. They still seem sturdy and zip smoothly, but they are not as large. These zippers are for the multiple exterior and interior compartments. They don't have the metal hoops for TSA locks, but you might be able to fit a TSA cable lock through the zipper pull tab holes (keep in mind, though, you might damage the pull tabs or zipper if the lock gets pulled hard)I really appreciate all the different storage areas available in this carry-on!Inside the main luggage area there two additional mesh pockets and one waterproof storage pocket. There are three external zippered pockets for easy access on the aircraft. One pocket is located on the back for holding your cell phone or car keys (But not both, unless you love to get your phone screen scratched!)Note: The Bold's "tablet" external storage pocket is designed for smaller tablets, and won't hold screen sizes larger than 11". The Travelpro website gives a list of example tablets that are or are not compatible with the carry-on.Note that while the Bold 22" Rollaboard has "expandable" capability, it really doesn't get you much more space - maybe an inch or so of additional depth. This is a feature that you will probably rarely use.Overall, I am very satisfied and impressed with the Travelpro Bold 22" Rollaboard construction and design. I had to search through a lot of luggage online before deciding on the Travelpro Bold line. I picked this up on sale, so it was a nice bonus!
