Security checks are definitely the most stressful part of a flight.
Especially if you are traveling with a carry-on bag, you need to make sure that you comply with all the rules and do not have any prohibited items in your bag.
Sometimes, however, items that might not seem appropriate to go on an airplane are accepted on most flights. Let’s see what they are and why they can be safely transported by plane.
Frozen Solid Foods
The TSA’s liquid rule contains an interesting loophole: frozen items don’t count as liquids.
A retired flight attendant shared on social media a memorable situation: “A business traveler brought a whole gallon of frozen soup through security. The passenger explained it was his grandmother’s recipe for his sister’s wedding. The item passed inspection because it remained frozen solid.”
It looks like travelers regularly transport frozen milk, smoothies, ice cream, and any kind of other liquid through security checkpoints.
Success depends on keeping these items completely solid until passing through screening. According to the official TSA guidelines, “frozen liquid items are allowed through the checkpoint as long as they are frozen solid when presented for screening.”
2. Live Fish in Water
While the 3-1-1 liquid rule remains strict, live fish in water containers receive special treatment.
Recently, at LAX, a marine biologist successfully transported rare tropical fish through security by informing security in advance and providing proper container documentation.
A pet store owner who regularly flies with exotic fish specimens reports: “Security officers often show compulsion with the fish. Some even assist in finding the best screening lane to minimize stress on the animals.”
The water containing live fish remains exempt from liquid restrictions, though documentation of species and origin facilitates the process.
The idea behind this exception is that the fish would not remain alive if the liquid contained dangerous substances.
3. Medical Liquid Exceptions
Beyond standard restrictions, travelers with medical conditions can have some exemptions.
For example, with proper documentation, a person with diabetes could travel with 500ml of insulin, ice packs, liquid glucose, and medical equipment.
The exemption extends to other medical necessities, including liquid medications and special dietary requirements.
4. Fresh Eggs and Uncooked Meats
Contrary to popular belief, raw food items pass through security. Some chefs regularly transport special cuts of meat and farm-fresh eggs.
TSA agents recommend proper packaging to prevent leakage and contamination.
In some cases, you’ll need temperature control, specially designed containers, and even security declarations to ensure a smooth passage through the checks.
5. Unexpected Electronics
While most travelers focus on laptops and phones, larger electronic items often raise eyebrows yet remain perfectly legal.
For example, a film producer could transport an entire professional lighting setup. Just make sure to arrive early arrival because the inspection can take some time.
The same thing applies to professional photographers who often transport extensive equipment setups, including multiple cameras and lenses. The important thing is to have everything organized and in the proper cases. The agents will most likely ask you to open everything to check the content carefully.
6. Metal Medical Implants
Modern security technology accommodates various medical devices and implants. The TSA has established protocols for screening passengers with medical implants, and these travelers have the right to request private screenings and may carry medical documentation, though it’s not required.
Understanding proper protocols makes security screening less stressful. TSA staff receive thorough training for this situation, so don’t be afraid to assert your rights.
7. Musical Instruments
Professional musicians probably already know that most instruments pass through security.
Obviously, some musical instruments are very delicate and quite expensive, so if you’re traveling with a 300-year-old Stradivarius, be sure to notify the staff and arrive early at the airport.
Even larger instruments like cellos pass through security with proper arrangements.
8. Sports Equipment
While baseball bats and golf clubs require checking (because they could become weapons), certain sports equipment surprisingly passes security.
Paralympic athletes regularly transport specialized equipment through checkpoints, demonstrating how security protocols adapt to even unique situations.
A professional fencer who often travels with equipment, responded on Instagram to a fan’s question asking how he was able to fly.
He said: “Common assumptions about fencing equipment prove incorrect when proper documentation and packaging are utilized.”
9. Essential Oils and Aromatherapy Items
Despite liquid restrictions, essential oils in small containers could still be carried.
The usual rule of 3-1-1 applies, where “3” means no larger than 3.4 ounces or 100 milliliters.
Essential oil bottles are usually 15ml each, so there is no problem with them.
10. Unusual Personal Care Items
Finally, it is interesting to note that some seemingly suspicious personal care items receive clearance in most airports.
For example, a makeup artist confirmed to us that it was possible to transport liquid latex, theatrical blood, body paint, and special effects makeup.
Once again, it’s important to respect the size restrictions e and have everything organized and labeled.
If you need to bring more than what can fit in a zipper bag, let the staff know before security screening begins or, for added peace of mind, contact the airport or airline you are traveling with in advance.
