It is time for some new luggage. Specifically, I'm looking for something that can take me through three or four days with ease and style, and be carried onboard an airplane; my current black nylon square thing on wheels is in need of a supplement. I have looked at several brands in a few different stores, and I really like the Shorthorn, by Mulholland Brothers. It's an FAA approved size, the construction and quality seems to be excellent, and I've found a dealer who can offer me a good discount. It looks like the comparable bag from Tumi is this expandable carry-on. While not explicitly FAA approved, and though I'm not crazy about its looks, but the various pockets and such makes it seem more versatile. I'm familiar with the products that Tumi make, but I have no experience with Mulholland Brothers. Can anyone offer an opinion or anecdote? Or suggestions of other brands I should be looking at? Thanks in advance.
