Several months ago I purchased the Briggs & Riley 22 inch Expandable Carry-On Series 200Briggs & Riley which when expanded is one of the largest by volume carry-on bags on the market. I have used it on two 2-week long business trips and feel it is the best carry-on available. The curved corners make it look smaller than the “Business” equivalent Briggs & Riley 21 inch Expandable Carry-On or the Tumi Alpha International Expandable Carry-On. This is important when boarding as you don’t want the flight attendants at the gate to target your bag for gate check. The expansion is 3 inches, creating 38% more room in the bag, while providing a small profile when the extra space isn’t required.
