I have the BR International, 2 cabin bags and a tote. All fit the carryon requirements by all airlines.
I just got back from Indonesia where I had to haul gear around as well as fulfill airline weight requirements. My larger non spinner cabin bag fit into the smaller overhead bins on the propellor planes. My expandable international, which I had to check due to it being expanded, fit everything I needed into it. (Fins have their own bag). We were on the go and having 2 bags made life easier.
The warranty is fantastic. BR replaced my wheels and covered all shipping costs on my international bag. A Few years ago they had redesigned the wheels to prevent tipping, which was a previous issue, and updated my bag at no cost to the new wheel design. Their warranty is lifetime.
Also, the retractable handle does not take up space in the main compartment. The bottom of my bag is flat. The bags stack easily with a design you pull and twist to attach the bags. Bags stay securely attached and balanced while wheeling them around. The tote bag fits everything I need and will fit a purse to meet the 2 item only carryon requirement.
They are pricey, but worth it due to warranty and design. Also, you reach a point in life where it feels good to travel with something nice but doesn’t call attention like a designer luggage set.
