Found a new favorite soda in one of your travels and want to take it home? Or maybe coke in a can from Japan just tastes different?
Whatever your reason for wanting to bring a soda in your checked luggage is, you can relax because you can put soda cans in your checked-in luggage.
There are rumors that pop cans explode on airplanes. But, we know that it's incorrect for the most part because cabin crews serve soda on flights.
But that's on the cabin and not the cargo, you say?
No worries, the air pressure in the aircraft cargo holds is the same as in the cabins.
The reason people believe that carbonated products, or any cans in general, will explode on a plane is because of the pressure.
Although that's not entirely impossible, there's a meager chance of that happening.
First, tin cans are sturdy containers.
Second, although soda cans can indeed be affected by pressure, aircraft cargo holds are pressurized by default.
The pressure on the cargo holds must be completely depressurized for any can explosion to happen.
And since air pressure in the commercial airline cargo holds the same as the cabin's, if any depressurization happens, you'd be more worried about staying conscious than a soda can explosion.
Damages like slight leaking or spraying due to changes in pressure and even temperature are more likely to happen.
A warmer temperature or if the cargo hold gets hit by the sun for too long may cause the soda to foam and potentially leak. This is because surface tension increases when the temperature rises.
Fortunately, aside from most modern cargo holds being temperature-controlled, they are also insulated for fire protection and prevent cargo from getting too cold.
Although it happens, pressure and temperature variations in the cargo holds aren't usually enough to cause damage.
That said, malfunctions can occur, so leakage may still happen in your soda cans.
But, with proper packing, you can avoid sweet and sticky explosions all through your baggage.
There are no limits on how much liquid you can pack on your checked-in baggage, generally. So you can take as much soda in your checked-in baggage as you want.
Soda cans should never be thrown as-is into your luggage.
You can safely transport your soda by wrapping it in bubble wrap or similar material. This protects it and your other items from leaks and cushions them from any impacts. Just make sure to close it tightly so there is no way the fluid can come out in case of a leak.
You can also try packing soda in a cooler bag, styrofoam box, or any waterproof container. This way, you won't risk damaging anything else in your suitcase. But those will take quite the space in your baggage and could be expensive.
Instead, you can just protect your soda cans with double-sealed bags. Any waterproof bag, plastic bags with zipper seals like Ziploc, or even plain grocery bags would work as long as you seal it tightly.
When placing the cans in your baggage, place them in the middle and surround them with other items that can be used as padding, like clothes.
Placing your cans as far away from other hard items and the sides will ensure that they won't get punctured, dented, or squished even when your luggage is handled roughly. This is also the reason why you should not place them beside fragile items such as glass bottles of wine or perfume. Also, wrap them individually.
To check if you packed them securely, shake or tap the case to see if the cans move or knock against each other. Rearrange and add more padding materials if needed.
Yes, you can take soda cans in your carry-on bags, but the cans of soda should follow the 3-1-1 liquids rule. Only less than or equal to 3.4oz/100 ml will be allowed. A standard-size coke can has 355 ml, so 100 ml is a pretty small amount, and repacking it won't be worth it. You can just buy one after the security check or purchase one on the flight if you really need a fizzy drink.
The 3-1-1 Liquid Rule is a rule by TSA or Transportation Security Administration that is also generally followed by most airlines.
It states that:
3 - You can bring 3 oz or 100ml per item of liquid
1 - You should place those 3 oz containers in one clear quart-sized plastic bag. You can bring as many 3 oz containers you can fit in your quart-sized plastic bag.
1 - Each passenger can only bring one of the quart-sized plastic bags with them.
The TSA started regulating the amount of liquid you can take with you as a precaution against terrorism. There was an incident where terrorists concealed chemicals in seemingly harmless liquid items.
You can take as many soda cans as you want in your checked-in bags since there is no limit.
However, you should ensure that you pack them in a sealed waterproof bag or container and surround them with padding material to even lessen the small risk of them leaking.
Also, keep in mind that even though you prepared as much as you can, packaging and cargo hold malfunctions can still happen; thus, some leaks may also happen.
