You’re standing at the gate. The boarding agent is eyeing the line like a hawk, and suddenly, they point at your bag. "That looks a bit large, can you put it in the sizer?" It’s the moment every traveler dreads. If you’ve bought into the Away hype—and honestly, most of us have—you’re likely carrying one of their two flagship rollers. But here is the thing: away carry on dimensions aren't just numbers on a spec sheet. They represent the razor-thin margin between a stress-free overhead bin experience and a forced gate-check that ends with your laptop getting tossed into the cargo hold.
Away basically built an empire on two sizes. You have "The Carry-On" and "The Bigger Carry-On." Simple names, right? But the reality of international versus domestic travel makes that distinction huge. I’ve seen people breeze through JFK only to get stopped in Heathrow because they didn't realize that an extra inch of "Bigger" actually matters to British Airways.
Breaking Down the Bare Metal Numbers
Let's get the raw data out of the way first. You need the exterior measurements because that's what the airline cares about. They don't care about the internal volume or your clever packing cubes. They care about the wheels and the handle.
For the standard Away Carry-On, we are looking at 21.7" x 13.7" x 9". This is the safe bet. This is the bag that fits in almost every overhead bin on the planet, including those picky European budget carriers like Ryanair or EasyJet (though you usually have to pay for the privilege of a bin spot anyway).
Then there is the Bigger Carry-On. This one measures 22.7" x 14.7" x 9.6". On paper, it’s just an inch here and there. In practice? It’s a beast. It’s designed specifically for US domestic "Mainline" carriers like Delta, American, and United. These airlines tend to have slightly more generous bins. But—and this is a big "but"—if you are flying a smaller regional jet, like a CRJ-900, even the standard Carry-On might struggle.
The Weight Factor and the "Ejectable" Battery
Dimensions are only half the battle. If your bag is the right size but weighs 40 pounds because you packed three pairs of boots, some airlines (looking at you, Lufthansa) will still make you check it. The standard Away Carry-On weighs about 7.1 lbs, and the Bigger one is around 7.4 lbs. That’s actually a bit heavy for a hardside bag. You lose a chunk of your weight allowance just to the polycarbonate shell.
And we have to talk about the battery. Away’s signature move was the built-in power bank. It’s a 37-watt-hour lithium-ion battery. Most people forget that while it’s TSA-compliant, it must be removable. If you are forced to gate-check your bag because the flight is full, and you can’t get that battery out because the spring-loaded mechanism is jammed? The airline won't let the bag on the plane. Period. It's a fire hazard in the hold.
Does it Actually Fit? Real-World Scenarios
I’ve spent years watching people struggle with these bags. Honestly, the "Bigger Carry-On" is a bit of a gamble if you travel globally.

- United Airlines: They are notoriously strict. Their official limit is 22" x 14" x 9". Technically, the Bigger Carry-On is over by 0.7 inches in height and 0.7 inches in width. Does it fit? Usually, yes, because overhead bins have a little wiggle room. But if the flight is packed and the agent is having a bad day, they can technically deny it.
- Delta: Generally more relaxed. They don't have a strict weight limit for carry-ons on most domestic routes, and their bins on the newer A321neos are massive. The Bigger Carry-On fits sideways (on its side) in those new bins, which is a game changer.
- Southwest: These guys have some of the biggest bins in the industry. You could probably fit a small house in there. The Bigger Carry-On is zero problem here.
The Interior vs. Exterior Debate
When you look at away carry on dimensions, you’re often looking at the box it comes in. Inside, you lose space to the handle housing. This is the "hidden" tax of hardside luggage. The telescoping handle rails run down the inside of the bag, creating two bumps. You have to pack around these.
Away tries to compensate for this with their compression system. It’s basically a high-density plastic flap you buckle down over your clothes. It works. You can squeeze a lot of air out of a week's worth of t-shirts. But don't let the compression fool you into overstuffing. If you bulge the bag, those 9 or 9.6 inches of depth quickly turn into 11 inches. Once the polycarbonate shell bows out, it won't slide into a sizer.
Material Matters: Aluminum vs. Polycarbonate
Away also sells an "Aluminum Edition." If you choose this, the dimensions stay roughly the same, but the weight skyrockets. We’re talking 10.1 lbs for the standard size. That is almost 3 lbs heavier than the plastic version. If you are flying an airline with a 15kg (22lb) carry-on limit, you’ve just used half your weight on the suitcase itself. It looks cool, sure. It feels like a tank. But it’s a logistical nightmare for strict weight checks.
The "Flex" Version: A Blessing and a Curse
Recently, Away introduced the "Flex" models. These have a zipper expansion that adds about 2.25 inches of depth.
- Standard Flex: 21.7" x 13.7" x 11.25" (expanded)
- Bigger Flex: 22.7" x 14.7" x 11.5" (expanded)
Here is the trap. Once you unzip that expansion, you are no longer carrying a carry-on. You are carrying a checked bag. Almost no airline on earth accepts an 11.5-inch deep bag in the overhead. The Flex is great for the trip home when you’ve bought too many souvenirs and don't mind paying the checked bag fee, but don't expect to roll that expanded beast onto the plane.
The Softside Alternative
Away also dabbled in softside luggage. The dimensions are similar, but the "give" of the fabric is the real benefit. If you’re a quarter-inch over, a softside bag can be squished. A polycarbonate shell cannot. If the sizer is tight, the hardside bag will simply stop.
Why the "Bigger" Carry-On is Dominating (And Why It Shouldn't)
Marketing is a powerful thing. Most people see "Bigger" and think "Value." Why wouldn't I want more space for the same price? But the away carry on dimensions of the Bigger model actually disqualify it from "Personal Item" status and make it a liability on international carriers like Air France or KLM.
If you are a "one-bag" traveler who wants to buy a suitcase and never worry about it again, the standard size is the smarter play. It’s the universal donor of the luggage world. It works everywhere.
Tips for Maximizing the Dimensions
- Heavy items near the wheels: This keeps the center of gravity low and prevents the bag from tipping, which can make it look larger and more "problematic" to gate agents.
- The "Squish" Test: Before you leave for the airport, measure the depth at the thickest point. If it’s bulging, use the compression straps to pull it back into its 9-inch frame.
- Handle down: Always ensure the telescoping handle is fully recessed before trying to fit it into a sizer. Even a half-inch of handle sticking out can fail the test.
Final Technical Insights
The wheels on an Away bag are "360-degree spinners." They are high-quality, but they add about 2 inches to the total height of the bag. When you compare Away to a traditional two-wheeled "rollaboard," you’re actually getting less packing volume for the same exterior height because those spinner wheels are "dead space" that sits outside the packing compartment.
Actionable Steps for Your Next Trip
- Check your tail number: If you’re flying a small Embraer or Bombardier jet, expect to "valet" or "pink tag" your Away bag at the jet bridge, regardless of whether it's the standard or bigger size. Those bins are just too small.
- Invest in a luggage scale: Since Away bags are on the heavier side (7+ lbs), knowing your packed weight is just as important as knowing your dimensions.
- Remove the battery before the line: Don't wait until you're at the front of the boarding queue to fumble with the battery release. Do it while you're sitting at the gate.
- Measure your most frequent airline: If 90% of your travel is on Southwest or JetBlue, go with the Bigger Carry-On. If you have a trip to Europe or Asia once a year, stick to the standard model to avoid the "Gate Check of Shame."
Ultimately, the best bag is the one you don't have to think about. Knowing your away carry on dimensions allows you to walk up to the gate with the confidence of someone who knows exactly where their bag is going to spend the next six hours. Avoid the Flex expansion unless you're prepared to visit the baggage carousel, and always prioritize the exterior height—including the wheels—over the internal capacity.
Travel is stressful enough. Your suitcase shouldn't be the reason you're sweating at 30,000 feet. Stick to the specs, understand the airline's "real" limits versus their "stated" limits, and pack like a pro who knows that an inch can make all the difference.
