Related: Away Luggage Ranked: Which Carry-On Is Actually Worth It?
I was the guy in the orange vest at O’Hare. I saw a thousand bags an hour roll down the belt, and I watched a ~$700 Tumi get crushed by three stacked rollaboards. The sizers at the gate are getting smaller, and the “22x14x9” rule printed on every manufacturer’s website doesn’t match the metal frame I used to stand next to.
The 22x14x9 rule isn’t universal. Real flyers report which bags fit which airlines, get the actual bin limits in one chart.
The best carry-on for most US flyers right now is the Freeform Hardside 21-inch, because it sneaks under the strictest mainline sizers while still giving you enough room for a week of clothes.

I fly 120 segments a year. I’ve got status on two airlines I’m not supposed to mention in reviews, so I won’t. I’ve also got a 70-pound lab mix named Juno who sleeps on every softside bag I own. That’s the durability test. If the bag survives a 70-pound dog curling up on it for a year, it’ll survive the overhead bin.
For carry-ons, I run the gate test: does it fit the sizer at O’Hare on a CRJ-900, does it survive the belt when I get forced into a gate check, and does the zipper still work after five flights? I measure with calipers. I weigh on a scale. I check the zipper pull 50 times. I check the seam stitching under the zipper, the spot where I’ve seen cheap bags fail.
The sizer problem
Airlines are shrinking sizers. I’ve seen it happen. The bag that fit last year doesn’t fit this year. American Airlines still lists 22x14x9. Delta lists 22x14x9. United lists 22x14x9. But the actual metal frames at the gate? They vary by aircraft, by gate, and by how strict the gate agent is feeling that day.
The 21-inch height is the sweet spot. A 22-inch bag with a slightly rounded top can wedge in tight. A 21-inch bag clears the frame with room to spare. That’s why I keep coming back to the 21-inch category.
Freeform Hardside 21-inch
I’ve been testing this one for four months. It’s the bag I reach for when I’m flying United and I know the sizer at my gate is one of the smaller ones.

The shell is polycarbonate, which means it flexes instead of cracking. I’ve thrown it down a set of stairs. It came back with a scuff on the corner that wiped off with a damp cloth. The zippers are smooth, not beefy like the Shacke Pak cubes I review, but they haven’t failed yet.
The interior is where it loses points. The divider is basic, and there’s no built-in TSA lock. You’ll want to bring your own. At ~$110, that’s a fair trade. Buyers on Amazon say the same thing. One reviewer from July 2025 said the wheels are quiet and roll well on carpet and tile. Another said the handle locks into place without the wobble you get on cheaper bags.
Compared to the 21" Hardside, the Freeform feels more solid. The is expandable, which is nice, but buyers report the handle gets wobbly after a few months. I’ve seen that pattern before. A wobbly handle is the first sign a bag is headed for the trash bin.
Should you buy it? If you fly mainline US airlines and you want a bag that fits the sizer without a fight, yes. If you need a TSA lock built in or you pack so heavy you need the expansion, look elsewhere.
21" Hardside with Spinner Wheels, Expandable
This is the budget pick that has a problem.
At ~$90, it’s cheaper than the Freeform, and the expansion zipper is genuinely useful. I packed it full for a week in New York, expanded it on the way back with a jacket and two bottles of bourbon, and it still fit the sizer on Delta. That’s the good news.
The bad news is the handle. Buyers on Amazon have been saying it since 2023: the handle wobbles. One reviewer from March 2024 said the handle started shaking after five trips. Another from November 2024 said the telescoping handle got stuck halfway up and wouldn’t lock back down.
I’ve seen this exact failure on the belt. A stuck handle means you’re carrying the bag, and a carry-on you have to carry isn’t a carry-on.
The wheels are fine. The zippers are fine. The shell is fine. But the handle is the part you touch every time you move the bag, and it’s the part that fails.
Compared to the Freeform, this one wins on price and expansion. It loses on the handle. If you only fly twice a year and you’re gentle with your gear, it might last you. If you fly monthly, spend the extra ~$20.
ENDURANCE 20-Inch Hardside
This is the lightest bag in the group. I weighed it at 5.8 pounds, which is a pound and a half less than the Freeform. That matters when you’re hauling it through O’Hare at 5 AM.
The 20-inch height is the big selling point. It fits every sizer I’ve tested, including the CRJ-900 regional jets that make bigger bags get gate checked. I flew this one on a United Express flight to Des Moines and it went in the bin without a fight.
The trade-off is depth. The interior is shallow, so bulky items like a hoodie or a pair of boots eat up the space fast. I packed it for a three-day trip and it was full. A week-long trip would need a second bag or a laundry service.
Buyers on Amazon say the same thing. One reviewer from June 2025 said it’s perfect for a weekend but tight for anything longer. Another said the handle is solid and the wheels are smooth. At ~$80, it’s a good deal for the flyer who packs light and flies regional.
Compared to the 20" Carry-On, the ENDURANCE feels more solid. The has a thinner shell, and one buyer said it dented on the first flight. I haven’t seen that with the ENDURANCE yet, but I’ve only had it three months.
20" Carry-On with Spinner Wheels
I wanted to like this one. At ~$70, it’s the cheapest bag in the group, and the price is tempting.
But the shell is thin. I noticed it the first time I picked it up. The polycarbonate flexes more than the Freeform, and when I threw it down the stairs in my Runway Test, it came back with a dent in the corner. Not a scuff. A dent.
A buyer on Amazon from August 2025 said the same thing. First flight, checked it at the gate, came back with a dent. That’s the risk you take at ~$70. The zippers are fine, the wheels are fine, but the shell is the part that protects your stuff, and this one doesn’t protect as well as the others.
It fits the sizer at 20 inches, and the spinner wheels are smooth. If you’re on a tight budget and you only fly once or twice a year, it might work. But I’d rather spend the extra ~$10 and get the ENDURANCE, which has a more solid shell.
21" Carry-On Expandable
This one sits between the budget bags and the Freeform on price, at about ~$100.
The expandable zipper is the selling point. I expanded it for the return leg of a trip to Nashville and it fit the sizer on American. The expansion adds room on the outside, not inside the bag, which is a subtle difference. Some buyers expect the expansion to add interior depth, but it doesn’t. It adds height and width to the exterior, which means you have to be careful it still fits the sizer.
Buyers on Amazon have noted this. One reviewer from April 2025 said the expansion made the bag too big for the sizer on a regional jet, and they had to gate check it. That’s the risk.
The shell is solid, the handle is sturdy, and the wheels are good. It’s a fine bag, but the expansion feature is a trap if you’re not careful. If you don’t need the expansion, the Freeform is a better choice for the same price.
20" Hardside Lightweight
This is the newest bag in the group, and it’s still in my rotation.
The color options are the standout. I’ve got the blue one, and it’s easier to spot on the carousel than any black bag. That’s a real benefit when you’re waiting at baggage claim after a gate check.
The wheelbase is solid, and the bag rolls straight. I pushed it through a crowded terminal and it didn’t veer. The interior straps sit awkwardly, though. They’re positioned in a way that doesn’t hold a stack of packing cubes in place. I had to rearrange my Shacke Pak cubes three times before they stayed put.
At ~$75, it’s a decent deal, but the interior design is a miss. Buyers on Amazon from July 2025 said the same thing about the straps. If you pack loose clothes without cubes, you won’t notice. If you use packing cubes, you will.
The bottom line
The sizer is the enemy. Airlines are making them smaller, and the bag that fit last year might not fit this year. The 21-inch height is the sweet spot for mainline carriers, and 20 inches is the safe bet for regional jets.
The Freeform Hardside 21-inch is the best all-around carry-on I’ve tested this year. It fits the sizer, survives the belt, and the shell holds up. The handle is solid, the zippers work, and at ~$110, the math works out.
The ENDURANCE 20-inch is the pick for regional flyers who pack light. The 20-inch height fits everything, and the weight savings are real.
Skip the if you check your bag at the gate. The shell dents too easily.
I’ve got three more direct-to-consumer polycarbonate carry-ons under ~$150 in my rotation right now. I’ll report back when I’ve flown them through five segments each. If one of them beats the Freeform, I’ll tell you. That’s the deal.
