Budget airlines keep finding new things to charge for, and travellers keep finding new ways around it. The latest: wearing your packed clothes onto the plane, or stuffing them into a pillow, to dodge carry-on fees. Videos of passengers boarding with padded stomachs, exaggerated curves and suspiciously bulky neck pillows have made this one of the more talked-about travel hacks of recent years.

The first question most people ask is whether it's actually legal. In the US, yes — no state or federal law prohibits wearing extra layers or hiding clothes in a pillow. The catch is that airlines can refuse boarding if they catch you, and they're within their rights to do so. Get caught and you could lose your ticket entirely, or be sent back to repack within the rules. You won't face fines from TSA or law enforcement, though — your beef is with the airline, not the authorities.

There are two main methods. Wearing clothes under clothes is the trickier option: lumps and bumps tend to invite scrutiny, and you may be in for a pat-down at security. Some travellers sidestep this with purpose-built gear like the Stuffa vest and jackets, which hide multiple compartments inside ordinary-looking outerwear. The pillow route is more popular and, frankly, easier. Neck pillows and regular pillows can be de-stuffed or have their foam removed, and even slim wraparound pillows hold more rolled-up clothing than you'd expect. Clothes themselves pass security fine — anything odd-looking might get a second look, but fabric isn't a prohibited item. Just make sure there's genuinely nothing but clothes rolled up in there, because hiding anything at an airport is a bad look.

So should you try it? That comes down to risk tolerance. Beyond being denied boarding, you could lose elite status with an airline, and a flight spent compressed under six layers isn't anyone's idea of comfort. But there's a real case for it in the right circumstances. On a short hop with a budget carrier, a $50 carry-on fee can double the cost of the fare itself. The hack makes most sense when you're nearly within your personal-item allowance anyway, when you'll be leaving things behind at your destination (a gift for family, say), or when you're headed somewhere cold and genuinely need bulky gear like gloves and thick hats you'd otherwise have to pack.

What it's not suited for is long-haul or extended trips — squeezing a full holiday wardrobe into your clothing and a pillow is a fast route to misery. Used narrowly, though, it's a legal, if awkward, way to keep a cheap flight actually cheap. The trade-off is simple: your dignity and a possible boarding denial versus a fee that might cost more than your seat.
