Yes, 55x40x23 cm luggage is generally considered cabin luggage for most airlines, as it falls within the common carry-on size limit of 55x40x20–23 cm. However, some low-cost carriers have stricter size or weight restrictions, and allowances may vary by airline and fare type. Always check your specific airline’s cabin baggage policy before traveling to avoid extra fees or gate checking your bag.
Where 55x40x23 Fits (and Where It Doesn’t)
Airline Type Typical Allowance Will 55x40x23 fit? Major US Carriers (United, Delta, American) 56 x 36 x 23 cm Yes (usually fits the depth) European Budget (Ryanair, Vueling, Wizz Air) 55 x 40 x 20 cm No (3 cm too deep) Premium International (Lufthansa, Air France) 55 x 35 x 25 cm Yes (if the width is under 35/40) British Airways 56 x 45 x 25 cm Yes (very generous) The Best 55x40x23 Luggage (and Why It’s a Smart Pick)
Choosing a 55x40x23 luggage piece is a strategic move for travelers who fly with “mainline” carriers but want to maximize every inch of packing space. If you aren’t flying ultra-low-cost carriers like Ryanair, this size offers roughly 5-7 liters more volume than standard slim bags.
Top Recommendation: Samsonite S’Cure Hardside Luggage
The Samsonite S’Cure is often cited as the best 55x40x23 luggage for frequent flyers. It’s built with a lightweight polypropylene shell that is incredibly durable but maximizes the interior dimensions.
- Why it’s a winner: It features a 3-point locking system (no zippers to burst) and fits perfectly in the overhead bins of United, Delta, and British Airways.
- Pro Tip: If you’re worried about the 23cm depth, the S’Cure’s integrated seal makes it more “compact” than zippered bags that bulge when overpacked.
Often yes in Europe, but some airlines and fares will say no.
If you have ever wondered, Is 55x40x23 luggage considered cabin luggage?, you are not alone. I have flown with this size on dozens of routes, and the answer changes by airline, route, and even fare type. In this guide, I break it down with clear rules, real checks, and simple tips you can trust.
What 55x40x23 really means, and how airlines read it
The size 55x40x23 cm includes the wheels and handles for most airlines. That part is key. If yours is hard-shell and rigid, 23 cm is the full depth, and that may be a tight fit in sizers.
Convert it to inches and you get roughly 21.7 x 15.7 x 9.1. Many US airlines use 22 x 14 x 9, so width and depth can be the blockers. If you ask, Is 55x40x23 luggage considered cabin luggage?, the shape and give of the bag matter as much as the numbers.
Is 55x40x23 luggage considered cabin luggage? Airline-by-airline breakdown
For most travelers, Is 55x40x23 luggage considered cabin luggage? depends on your airline and fare. Policies below reflect common published limits. Always check your exact flight and ticket, since rules can change and fares can cap size or weight.
- Lufthansa Group, SWISS, Austrian, Brussels Airlines: 55x40x23 allowed on most fares, often with 8 kg limits.
- Turkish Airlines: 55x40x23 allowed, common 8 kg limit in economy.
- Air Canada: 55x40x23 allowed, plus a personal item.
- British Airways: Up to 56x45x25, so 55x40x23 is fine.
- easyJet: 56x45x25 for larger carry-on with certain seats or options; otherwise smaller free item only.
- Ryanair: Priority carry-on cap is 55x40x20; 23 cm depth is too thick. Free item is much smaller.
- Wizz Air: With Priority, 55x40x23 is often allowed; without it, only a smaller underseat bag.
- Iberia: Typically 56x40x25, so 55x40x23 fits.
- Vueling: Many fares cap at 55x40x20 for overhead items unless you add Priority.
- Air France and KLM: 55x35x25; 40 cm width exceeds the 35 cm limit.
- Emirates: 55x38x20 in economy; 23 cm depth is over the limit.
- United, Delta, American, JetBlue, Alaska: 22x14x9 inches. 55 cm length is fine, but 40 cm width and 23 cm depth are over by a bit.
- Southwest: 24x16x10 inches, so 55x40x23 fits.
Bottom line: In much of Europe, yes. In North America and some Gulf carriers, your 55x40x23 may be too wide or too deep unless the bag compresses or staff are lenient.
New Rules! Ryanair Carry-On Luggage Size 2025: Dimensions & Baggage Tips
When 55x40x23 works well, and when it does not
If your trips are mainly in Europe, 55x40x23 is a safe, standard choice. Lufthansa, BA, and Turkish accept it, and airport sizers match those limits. Add Priority on low-cost carriers, and you are set.
Issues come up with Ryanair, Vueling, Air France, KLM, and many US airlines. Their boxes are narrower or shallower. A hard-shell case at 23 cm can get flagged, even if it would fit the bin.
On US carriers, I have fit 55x40x23 into overhead bins, but sizers and gate checks are hit or miss. Full flights and strict agents make the difference. If you care about a sure bet there, pick 55x35x22 or a soft 40 cm width.
Practical tips to make a 55x40x23 bag fit more often
If you still wonder, Is 55x40x23 luggage considered cabin luggage?, these steps raise your odds.
- Choose soft-sided. Fabric bags can compress by 1–2 cm at the sides and depth.
- Pack to shape. Keep the front pocket flat to reduce measured depth at 23 cm.
- Use compression cubes. They hold shape without bulging past limits.
- Wear bulky layers. Move heavy shoes or coats to your body during boarding.
- Check weight. Many European airlines cap carry-ons at 7–10 kg.
- Board early. Overhead space is the first thing to vanish on full flights.
- Know your fare. Priority or “Up Front” often unlocks larger carry-on sizes.
How airlines actually measure your 55x40x23
Airlines measure the whole thing. That means wheels, handles, and side pockets. A bag that is “55x40x23 without wheels” does not pass in most sizers.
If you need to shave a centimeter, loosen exterior straps or move items to a personal item. Tuck in straps and collapse handles. When staff ask, place the bag wheels-first into the sizer. A smooth drop-in looks smaller.
For those asking, Is 55x40x23 luggage considered cabin luggage?, these small moves often flip a no to a yes.
Real-world lessons from the road
I have carried a 55x40x23 cm roller on more than 100 flights. On Lufthansa and Turkish, it sailed through every time. On British Airways and easyJet with the right seat, it was also fine.
My only problems came with Ryanair Priority and US legacy carriers. Ryanair’s 20 cm depth cap meant a quick repack into an underseat bag, plus paying for a checked bag once. In the US, I passed bins but failed a sizer on a packed flight, and they gate-checked me.
From that, my rule is simple. If I will fly a mix of airlines, I ask myself, Is 55x40x23 luggage considered cabin luggage? If the trip includes Air France, KLM, or US carriers, I switch to a softer 55x35x22.

Common mistakes to avoid with 55x40x23 cabin bags
- Ignoring wheels and handles. They count, and they add 2–3 cm fast.
- Rigid shells on narrow-rule airlines. Slim soft bags beat hard shells on tight limits.
- Overstuffing front pockets. This pushes depth beyond 23 cm and gets noticed.
- Skipping fare details. Priority and seat choice often control what you can bring.
- Forgetting weight. Size may pass, but 9–10 kg scales catch many travelers.
When in doubt, ask yourself again, Is 55x40x23 luggage considered cabin luggage? If the route is mixed, play it safe or add Priority.
