The answer is yes, you can fly with canned food in your carry-on.
However, there are some important restrictions and considerations that you should be aware of before doing so.
The Transportation Security Administration (TSA) allows limited quantities of canned food items such as soups, stews, fruits, vegetables, and sauces in your carry-on baggage. However, it’s important that the cans are not more than 3.4 ounces (100ml) or larger than quart sized. If the cans are larger than these measurements, they must be placed in checked baggage.
When packing canned food items for travel, it’s important to remember that all liquids and gels must be placed in plastic bags and placed separately from other items in your carry-on. This includes any sauces or pastes that may come with the canned food item. All cans must also be unopened and any sharp objects such as can openers must also be placed separately.
It is also important to remember that even though you can bring canned food items through security checkpoints in your carry-on baggages, you cannot bring them onto the airplane itself. This means if you plan on bringing a meal on board with you for the flight, make sure to pack it in a separate container from other items such as laptops or books.
In conclusion, while it is possible to fly with canned food items in your carry-on baggages, there are some restrictions and considerations to keep in mind. Make sure all cans are unopened and within the size limit of 3.4 ounces (100ml) or smaller than quart sized and all liquids/gels must be placed in plastic bags separately from other items for easy security checkpoint processing. Finally, no canned goods are allowed on board the airplane so any meals you plan on bringing should be packed separately.
