| 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 (10.5×16.5×8.5") 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
Fits, but it's snug; an overstuffed or expanded bag could push it over. The tightest margin is just 0.5 inches on the shortest side, so pack light and avoid overstuffing.
What you're paying for
The Briggs & Riley ZDX Underseat Cabin Bag isn’t just about fitting under the seat; it’s about doing so with style and substance.
- Owners love its durable construction, which tends to hold up against the rigors of travel. It’s built to last, even if you’re not.
- The bag’s compact size makes it easy to maneuver through crowded airports or stuff into tight overhead bins when needed.
- It has a 10-year warranty, so Briggs & Riley is pretty confident in their product.

Frequently asked questions
Will the Briggs & Riley ZDX Underseat Cabin Bag fit as Air Canada's free personal item?
No. At 10.5×16.5×8.5" 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 ZDX Underseat Cabin Bag travels as your cabin bag.
Does overpacking or expanding the bag change whether it fits?
Yes, watch it. The bag fits at its listed size with only 0.5" to spare on its tightest side, so an expansion zipper or an overstuffed bag can push it over. Pack it flat.
Bottom line
Whether you choose the Briggs & Riley or one of its alternatives, you’re set for a smooth ride with Air Canada. Just remember: pack smart, and you’ll avoid any gate-check surprises.
