Whether you’ve crammed in one too many outfits or you’re wrestling with limited space for electronics, toiletries and flight attire (those planes can get so chilly!), a clever travel hack has been helping fliers dodge those annoying extra bag charges. But there’s the catch: This viral trick could backfire big-time.
So what’s the hack everyone’s talking about, and why are airlines cracking down on it? Read on to find out before your next flight.

What is the sneaky carry-on hack that’s gone viral?

Instead of cramming everything into your bag, grab a pillowcase and stuff it with soft items like T-shirts, leggings or swimsuits. Voila! You’ve got yourself a “travel pillow.” Most airlines don’t count pillows against your baggage allowance, so this clever disguise can let you board with an extra stash of clothes … with no added fee. Plus, stuffing your pillowcase with a hoodie or scarf gives you a soft, clean headrest for flights.
It’s been dubbed the ultimate budget travel hack by influencers who swear it’s helped them skip baggage costs time and time again. One TikTok user enthusiastically chimed in on a post, commenting, “Guys, this actually WORKS! I was skeptical at first, but I tried it—and it actually made it on the plane.”
And the best part? TSA typically doesn’t care. Yep—when you’re going through security, it’s not about what your stuff looks like; it’s about what you’re carrying. As long as everything inside your pillowcase is TSA-approved (think: clothes, not liquids or sharp items), you’re good to go … if you’re smart about it.
What’s the common mistake people make here?
The common mistake people make with this hack is overstuffing the pillowcase. When the pillowcase is clearly jammed with items, that’s where things get tricky. TSA is more concerned with what you’re carrying than how it looks (and the pillowcase will still go through the X-ray machine, of course), but agents may still decide to inspect it more closely if something seems off.
Here’s a pro tip: Neck pillows are a smarter choice for this hack. They’re compact, more discreet and typically breeze through security without raising eyebrows. What’s more, using fluffy or fur-covered pillowcases (like in the TikTok video above) takes this hack to the next level. The extra fluff helps conceal any lumps or irregular shapes, so the item is less likely to be flagged as problematic.
Do flight attendants care if you do this?
Think flight attendants aren’t watching? Think again. Flight attendants are doing more than just being friendly during boarding—they’re on high alert. As you walk down the jet bridge, they’re already scanning for oversized bags, sneaky extra items and, yes, even that oddly shaped “pillow” you’re clutching a little too tightly.
Interestingly, former flight attendant Arina Bloom once backed the hack in an interview with Business Insider, saying that “as long as there’s nothing prohibited inside, it’s totally fine.” But even if you manage to slip past the gate agent or the first crew member, there’s still a whole cabin crew on board. If they catch on, you could get called out in front of everyone, and your item could get a closer look—an embarrassing move if your pillowcase items are personal.
What will happen if you get caught?
Maybe nothing, maybe something. It really depends on who you’re dealing with. For example, airline staff may overlook this … or ask you to pay the baggage fee right there at the gate. And if you’re pulled over by TSA, you won’t get in trouble if it’s just clothes, but you might be asked to clarify what’s inside or even empty the pillowcase and repack—which could delay you and cause you to miss your flight.
There have also been cases in which passengers were escorted away from the gate for refusing to comply. As one TikTok user recounts, “I was at the airport and a girl in front of me did the same thing. They wouldn’t let her pass—unless she could fit the pillow in her bag.”
So if you’re going to try the hack, be smart about it. Have a payment method ready just in case, and don’t pack anything you can’t afford to lose—because you might end up tossing it in the trash to make your flight.
What are pillowcases also useful for when traveling?
Bringing a pillowcase is actually one of the most versatile travel hacks out there. It weighs practically nothing, takes up zero space and comes in handy in more ways than you’d expect, especially during summer travel when messes, sweat and last-minute beach stops are a given. Here are just a few of the ways that I—and many seasoned travelers—use a pillowcase on the go:
- Makeup bags: I keep a couple of older pillowcases on hand at home and use them as impromptu makeup bags when I travel. They’re soft, washable and perfect for wrapping around compacts and brushes so nothing breaks—or leaks—all over my clothes.
- Shoe bags: Wrap up your sneakers or sandals in pillowcases so they don’t get everything else in your suitcase dirty. And no, don’t use them as actual pillowcases after!
- Laundry bags: Pillowcases are perfect for keeping your dirty or damp clothes from mixing with clean ones. With this hack, you’ll have a handy laundry bag waiting for you at the hotel.
- Beach-tote liners: Throw your pillowcase into a straw bag to catch sandy flip-flops. You can also us it as a sun cover, makeshift towel and even a head wrap if you forget a hat at the beach.
- Packing-cube substitutes: Use your pillowcase to wrangle socks, undergarments or small items in your suitcase for better organization.
- Actual pillowcases: Yep, this is how pillowcases were meant to be used! I typically bring one for hotel stays because I don’t always trust the sheets or pillows. Slipping my own pillowcase over the hotel pillowcase gives me a little peace of mind and helps me sleep easier, especially in unfamiliar places.
