You’ve seen them. Those bright, plastic, animal-shaped boxes zooming through Heathrow or JFK, usually with a red-faced toddler clinging to the "horns" while a parent drags them along like a pack mule. The Trunki ride on case is basically a rite of passage for traveling families at this point.
But honestly? Most parents buy them for the wrong reasons.
They think it's a suitcase. It isn't. Not really. If you try to pack a week’s worth of clothes into one of these, you’re going to have a very bad time at the boarding gate. It’s a toy that happens to hold some stuff. Once you accept that, your airport experience gets a whole lot better.
The Dragon’s Den Rejection That Built an Empire
It’s hard to talk about Trunki without mentioning the most famous "fail" in British television history. Back in 2006, inventor Rob Law walked into the Dragons' Den and got absolutely mauled. Theo Paphitis literally ripped the strap off the prototype. The Dragons called it worthless.
Fast forward to 2026, and the company has sold well over 5 million units. It was recently acquired by a firm called Heroes for a reported £12 million. Not bad for a "worthless" idea, right?
The reason it survived—and thrived—is that it solved a very specific, very annoying problem: the "Gate 92" meltdown. You know the one. Your stroller is checked, your flight is delayed, and your three-year-old has decided their legs no longer function. The Trunki isn't just luggage; it’s a mobile seat and a distraction tool.
What’s Actually Inside (and What Isn't)
Let's talk specs, because this is where the "suitcase" part gets tricky. A standard Trunki has about an 18-liter capacity.
$18L \approx 4.75 \text{ gallons}$
That sounds like a lot until you realize the plastic shell is thick and the shape is awkward. Because it’s a "clamshell" design with two halves, everything tends to tumble out the second you open it on a cramped airplane floor.
Pro tip: Do not pack the "must-have" items at the bottom. Use the internal elastic "teddy bear seatbelts" for clothes, and keep the iPad, snacks, and wipes in a separate small pouch at the top.

The Real Specs
- Weight: About 1.7kg (3.8 lbs) empty. It's light, which is great because you'll be carrying it eventually.
- Max Weight Limit: It officially supports up to 50kg (110 lbs). I’ve seen kids way older than six riding these, but the steering gets... questionable.
- Dimensions: 46 x 20.5 x 31 cm. It fits in almost every overhead bin, and often under the seat in front of you (though it’s a tight squeeze on budget airlines).
The "Ankle-Buster" Maneuverability
Here is the cold, hard truth: the Trunki ride on case does not turn. The wheels are fixed. They go forward. They go backward. That’s it.
If you need to make a sharp left toward the Duty-Free shop, you have to physically lift the front of the case using the tow strap or watch your child perform a slow-motion tip-over. It takes a bit of a "knack." Most parents end up doing a sort of weird, swinging arc to navigate corners.
Also, watch your shins. If you are pulling a tired toddler at high speed, that hard plastic shell becomes a 4lb blunt instrument aimed directly at your Achilles tendon.
Is It Better Than a Stroller?
Kinda. But it’s not a replacement.
If you have a layover and your kid needs a nap, a Trunki is a nightmare. They can’t sleep on it. However, if you have a "stroller-resistant" toddler who wants to feel independent, the Trunki is a godsend. It gives them a "job." They are the pilot of the Ladybug or the Tiger.
Why the 2026 Models Are Different
The newer versions, particularly those produced under the Heroes ownership, have tightened up the latch system. Older Trunkis were notorious for "the explosion"—where the case would pop open mid-tow, scattering socks across the terminal. The new "lockable" catches (using that little plastic key on the strap) are much more secure.
The Competition: Trunki vs. The World
The market is crowded now. You’ve got the Stokke JetKids BedBox, which is way more expensive (around $250) but actually turns into a bed on the plane. Then there’s the MiaMily, which is basically a high-end suitcase with a seat on top.
So why do people still buy the Trunki?
- Price: It’s usually under $100/£50.
- Weight: It’s much lighter than the BedBox.
- Durability: You can drop these things down an escalator (don't, but you could) and they usually just bounce.
Common Misconceptions and Errors
A big mistake people make is thinking they can use this as their only bag for a child. Honestly, you've got room for maybe three outfits, a pair of pajamas, and some toys.
Another one? Thinking the strap is just for towing. That strap is actually your best friend. When the kid decides they want to run instead of ride, you can clip the strap to both ends and throw the whole case over your shoulder like a bulky messenger bag.
Actionable Steps for Your Next Trip
If you’re pulling the trigger on a Trunki for your next vacation, here is how to actually make it work:
- The "One-Side" Rule: Pack all the "heavy" stuff (shoes, denim) on the bottom half and the "light" stuff (diapers, t-shirts) on the top half. It lowers the center of gravity and makes it less likely to flip over when your kid takes a corner too fast.
- Bring the Key: That little plastic key is easy to lose. Loop it through the strap twice. If the case is locked and you lose the key, you’re looking at a very frustrating "surgery" with a flathead screwdriver in the departures lounge.
- ID is Vital: Every airport has fifty "Terrance" (the blue one) and "Trixie" (the pink one) cases. Put a massive, ugly sticker or a bright luggage tag on yours.
- Practice at Home: Let them ride it around the kitchen for a week before the trip. It wears down the stiffness of the wheels and gets the "tipping over" phase out of the way before you’re in a crowded security line.
The Trunki ride on case is a specialized tool. It’s for the gap between "I need a stroller" and "I can walk three miles to the gate." It won't hold your whole life, and it won't win any awards for precision steering, but it might just save your sanity when the flight board switches to "Delayed."
