You’ve got great taste in luggage, but Air Canada’s sizer might make you sweat. Let’s see if your Monos Carry-On Plus can hack it.
Short answer: borderline. The Monos Carry-On Plus is just 0.5" over Air Canada's 21.5×15.5×9" limit at 22×14×9". It usually squeezes through if you don't overpack, but a strict gate agent can flag it.
The Monos Carry-On Plus measures 22 by 14 by 9 inches, while Air Canada's published cabin-bag limit is 21.5 by 15.5 by 9 inches. On paper, this is a borderline fail, over by half an inch on its longest side.
How the Monos Carry-On Plus measures up against Air Canada
| Dimension | This bag | Limit | Verdict |
|---|---|---|---|
| Longest side | 22" | 21.5" | Over by 0.5" |
| Middle side | 14" | 15.5" | 1.5" to spare |
| Shortest side | 9" | 9" | Exactly at the line |
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") 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
It’ll often squeeze into the sizer or bin if not overpacked, but a strict gate agent could still flag it. Pack light and hope for mercy.
What you're paying for
The Monos Carry-On Plus is a sleek, well-built bag that owners rave about. When it fits, it’s a joy to travel with.

- It has a roomy interior with compression straps to keep your stuff organized and compact, which might help it squeeze into the sizer.

Frequently asked questions
Will the Monos Carry-On Plus fit as Air Canada's free personal item?
No. At 22×14×9" 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 Carry-On Plus travels as your cabin bag.
Does overpacking or expanding the bag change whether it fits?
Yes, this is the whole ballgame. The bag is already 0.5" over at its listed size, so overpacking or opening an expansion zipper pushes it further past Air Canada's limit. Pack it light and don't expand it.
Bottom line
Pack light and hope for the best, or go with one of the alternatives. Either way, happy travels!
