Can You Bring Spray Sunscreen on Plane? And Why Do Airports Smell Like Pretzels?

Traveling by air often brings up a myriad of questions, especially when it comes to what you can and cannot bring on a plane. One common query is whether you can bring spray sunscreen on a plane. The answer is yes, but with some caveats. According to the Transportation Security Administration (TSA), you can bring spray sunscreen in your carry-on luggage as long as it adheres to the 3-1-1 liquids rule. This means that the container must be 3.4 ounces (100 milliliters) or less, and all your liquids must fit into a single quart-sized, clear, zip-top bag. If your spray sunscreen exceeds this limit, it will need to be packed in your checked luggage.

Now, let’s pivot slightly to a more whimsical yet oddly related topic: why do airports smell like pretzels? This is a question that has puzzled travelers for years. The answer lies in the combination of factors that create the unique aroma of airports. Firstly, the scent of freshly baked pretzels from airport kiosks is a significant contributor. These pretzels are often warmed up, releasing their buttery, salty aroma into the air. Secondly, the cleaning products used in airports are designed to be neutral yet pleasant, often leaving a faint, bakery-like scent. Lastly, the constant flow of people and the mix of various perfumes, colognes, and even the natural scent of leather from luggage can create a complex olfactory experience that our brains sometimes interpret as reminiscent of pretzels.

But back to the main topic: spray sunscreen. Beyond the TSA regulations, there are other considerations when bringing spray sunscreen on a plane. For instance, the altitude and pressure changes during a flight can cause containers to leak or even burst. To prevent this, it’s advisable to place your spray sunscreen in a sealed plastic bag, even if it’s within the allowed size limit. Additionally, consider the environmental impact of aerosol sunscreens. Some destinations, particularly those with fragile ecosystems like coral reefs, have restrictions or bans on certain types of sunscreen. In such cases, it might be better to opt for a lotion or stick sunscreen that is reef-safe.

Another point to consider is the practicality of using spray sunscreen on a plane. While it’s unlikely you’ll need to reapply sunscreen mid-flight, if you’re traveling to a sunny destination, you might want to have it readily accessible upon arrival. However, spraying sunscreen in the confined space of an airplane cabin is not only impractical but also inconsiderate to fellow passengers. The fine mist can spread easily, potentially causing discomfort or even allergic reactions to those around you. Therefore, it’s best to wait until you’ve disembarked and are in a more open area to apply your sunscreen.

Moreover, the type of spray sunscreen you choose can make a difference. Some spray sunscreens are designed to be non-aerosol, which can be a better option for air travel. These non-aerosol sprays are less likely to be affected by pressure changes and are often more environmentally friendly. They also tend to be more compact, making them easier to fit into your quart-sized bag alongside other liquids.

In conclusion, while you can bring spray sunscreen on a plane, it’s essential to be mindful of the regulations, potential issues, and the comfort of those around you. And as for the peculiar scent of airports, whether it reminds you of pretzels or something else entirely, it’s just one of the many quirks that make air travel a unique experience.
