Common carry-on size restrictions (the numbers)
Most U.S. airlines allow carry-ons up to about 22 x 14 x 9 inches (56 x 36 x 23 cm), but limits vary by airline and aircraft. Some international and low-cost carriers are smaller, and personal-item limits (the bag that goes under the seat) are separate—so a carry-on that’s fine overhead can still leave you with a too-big “extra” bag.
What that means in practice: aim for a suitcase that stays within that 22 x 14 x 9 shape including wheels and handles, and plan for occasional tighter fits on smaller planes. If you’re flying a mix of carriers, the safest move is to pack like you’ll be measured—because sometimes you will be.
What usually gets flagged at the gate
- Depth: That “9 inches” is the one people accidentally exceed when a bag is overstuffed.
- Protruding parts: Wheels and handles count toward total size on many airlines.
- Two-bag confusion: Carry-on + personal item is typically allowed, but each has its own dimensions.
Where Away fits in
If you want a straightforward option built for quick trips, Away’s The Carry-On is the brand’s smallest suitcase and is described as sized to fit in overhead bins. If you tend to pack heavier, the The Bigger Carry-On is designed to maximize space and is described as sized to fit in the overhead bin of most major U.S. airlines—useful when you want room without jumping to checked luggage.
Less wrestling, more getting out of the airport
Away’s hard-shell carry-ons are built to be lightweight and durable, with details that make the overhead-bin routine feel less like a workout: smooth-gliding wheels for tight turns, an easy-grip top handle, and an additional underside grab handle for the lift-and-slide moment.
Pack to the limit without the bulge
Away’s interior compression system is designed to help you pack, organize, and protect more so your load stays controlled instead of ballooning past the depth limit. It’s the difference between closing your bag cleanly and sitting on it in a hotel room while your flight boards.
Choose your capacity, keep the carry-on convenience
The Carry-On: The smallest option in the lineup for quick trips and overhead-bin travel.
The Bigger Carry-On: A standard-size go-to designed to maximize packing space while still targeting overhead bins on most major U.S. airlines.
And if you like your travel gear to feel like yours, Away also offers foil monogramming—a small detail that makes the “which black suitcase is mine?” carousel problem a non-issue when you’re traveling with friends.
How to pick the right carry-on for size rules
Start with the baseline most travelers plan around: 22 x 14 x 9 in (56 x 36 x 23 cm). Then decide how much variability you need to cover. If you regularly fly smaller planes or a mix of airlines, leaning smaller reduces stress. If you mostly fly major U.S. carriers and want more room, a standard-size carry-on can be the sweet spot.
Match the suitcase to your trip style
Quick 1–3 day trips: Prioritize a compact overhead-bin suitcase and tighter packing.
4–7 day trips: Look for a carry-on designed to maximize space while staying within common overhead-bin expectations.
Frequent movers: Handles and wheels matter—airports are basically long hallways with obstacles.
A simple checklist before you buy
Know your “two-bag” plan: If you always bring a personal item, keep it truly under-seat sized.
Avoid depth creep: If you tend to overpack, pick a suitcase with built-in compression to keep the profile controlled.
Plan for the lift: An underside grab handle makes overhead bins less awkward, especially when you’re boarding late.
Bottom line: choose the smallest size that fits your routine. It’s the easiest way to stay on the right side of restrictions without turning every boarding line into a negotiation.
Built for real travel days
Away designs luggage for the parts of travel that actually happen: the sprint to your gate, the overhead-bin shuffle, the tight turn through a crowded aisle. That’s why the details focus on performance—smooth-gliding wheels, an easy-grip top handle, and an underside grab handle for the lift—paired with a lightweight, durable hard shell that’s been rigorously tested.
Inside, the compression system helps you pack with intention, not chaos—so you’re less likely to push your bag past common size limits just to squeeze in “one more thing.” Choose a compact carry-on for quick getaways, or step up to a roomier option designed for overhead bins on most major U.S. airlines. Either way, the goal is the same: fewer friction points between you and the part where you actually get away.
