Short answer: no, it doesn't fit. The Briggs & Riley Underseat Duffle is 1.5" over Air Canada's 21.5×15.5×9" carry-on limit, so it won't clear the sizer.

You're eyeing the Briggs & Riley Underseat Duffle for your Air Canada flight because you want something sleek and reliable. But will it slide past the gate agent, or is this a one-way trip to baggage claim?
Short answer: no, it doesn't fit. The Briggs & Riley Underseat Duffle is 1.5" over Air Canada's 21.5×15.5×9" carry-on limit, so it won't clear the sizer.
The Briggs & Riley Underseat Duffle does NOT fit on Air Canada. It's over by 1.5 inches on the shortest side, which means you'll be handing it over at the gate and digging into your wallet for that fee.
How the Briggs & Riley Underseat Duffle measures up against Air Canada
| Dimension | This bag | Limit | Verdict |
|---|---|---|---|
| Longest side | 16.5" | 21.5" | 5" to spare |

What counts toward the size
Airlines measure your bag at its largest points, and that includes the wheels, handles, and any bulging front pockets. The numbers above (11.5×16.5×10.5") are the bag's external dimensions, so that's exactly what a gate agent's sizer sees. Don't count on squishing it or tucking in a handle to gain space, what's on the spec sheet is what gets measured.
What happens at the gate
Air Canada's published cabin-bag limit is 21.5 by 15.5 by 9 inches. The Briggs & Riley Underseat Duffle measures 11.5 by 16.5 by 10.5 inches, putting it just over the limit on the shortest side by 1.5 inches.
What you're paying for

Frequently asked questions
Will the Briggs & Riley Underseat Duffle fit as Air Canada's free personal item?
No. At 11.5×16.5×10.5" it's a full-size carry-on, not a personal item. Personal items have to fit under the seat (much smaller, roughly 18×14×8" or less), so the Briggs & Riley Underseat Duffle travels as your cabin bag.
Does overpacking or expanding the bag change whether it fits?
It only makes it worse. The bag is already 1.5" over at its listed size, and packing light won't shrink a rigid frame. Expanding it pushes it further past the limit.
Bottom line
While the Briggs & Riley Underseat Duffle is a fantastic bag for many airlines, it's not the right match for Air Canada. But don't worry, there are plenty of other options out there that will keep you flying smooth and fee-free.
