You love your Monos Carry-On Plus for its sleek design and smooth wheels, but Lufthansa's sizers might not share your enthusiasm. Let’s see if you’re in for a gate showdown.
Short answer: borderline. The Monos Carry-On Plus is just 0.3" over Lufthansa's 21.7×15.7×9.1" 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 Lufthansa’s published cabin-bag limit is 21.7 by 15.7 by 9.1 inches. That leaves just 0.3 inches to spare on the longest side, barely enough room for a single sheet of paper.
How the Monos Carry-On Plus measures up against Lufthansa
| Dimension | This bag | Limit | Verdict |
|---|---|---|---|
| Longest side | 22" | 21.7" | Over by 0.3" |
| Middle side | 14" | 15.7" | 1.7" to spare |
| Shortest side | 9" | 9.1" | 0.1" 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 (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
This is a borderline FAIL on paper, over by 0.3 inches on its tightest dimension. It’ll often squeeze into the sizer or bin if you don’t overpack it, but a strict Lufthansa gate agent can flag it, and not overpacking helps.
What you're paying for
If you’re committed to your Monos Carry-On Plus, here’s how to maximize your chances of avoiding a gate check:
- Pack light. Every extra item increases the bag’s bulk, making that 0.3-inch overage even more noticeable.
- Arrive early and choose your sizer wisely. Some airport sizers are tighter than others, so look for one with a bit of wiggle room.
- Be prepared to argue. If you’re faced with a gate agent who’s feeling particularly strict, politely point out that the bag is only slightly over and that it fits comfortably in the overhead bin.

Frequently asked questions
Will the Monos Carry-On Plus fit as Lufthansa'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 0.3" over at its listed size, so overpacking or opening an expansion zipper pushes it further past Lufthansa's limit. Pack it light and don't expand it.
Bottom line
Whether you roll the dice with your Monos Carry-On Plus or switch to a more compliant bag, safe travels, and may the gate-agent gods be ever in your favor.
