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 (22×14×9.8") 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.

Frequently asked questions
Will the Monos Expandable Carry-On fit as Air Canada's free personal item?
No. At 22×14×9.8" 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 Monos Expandable Carry-On travels as your cabin bag.
Does overpacking or expanding the bag change whether it fits?
It only makes it worse. The bag is already 0.8" over at its listed size, and packing light won't shrink a rigid frame. Expanding it pushes it further past the limit.
Bottom line
The Monos Expandable Carry-On is a great bag, but it won’t pass Air Canada’s carry-on sizer. If you’re set on this bag, budget for gate-checking fees or look into alternatives that fit.
