Liquids on airplanes can be a very troubling subject. New regulations are being created all the time control one’s ability to carry liquids on airplanes every day. Usually, a small freezer bag full of personal liquid items is allowed, as long as nothing is over three ounces. TSA airplane liquid limits are now firmly enforced, and attempting to smuggle unauthorized liquids onto airplanes can have serious consequences. Certain controlled substances, such as liquid nitrogen or medication, is almost never allowed. These liquids are completely banned on airplanes.
It can be difficult to remember all the new regulations for airplane travel, but helpful guides have been placed at airports all over the world. With liquids on airplanes being such a source of concern in the modern world, examples of nearly all restricted liquids have been placed at informational booths in airports.
Some foods may be allowed on airplanes provided that they do not contain more than three ounces of removable liquid. Larger foods may be subject to search or authentication before one is allowed to board the aircraft. Aerosols are never allowed, as the count as a liquid on an airplane.
For those who simply must have their liquid refreshment, most planes have drinks on board to sell. However, purchasing drinks can be fairly expensive, and one should know their limit beforehand.
Bringing liquids onto airplanes can be fairly confusing; knowing the rules beforehand can make the difference between pleasant travel and a regulatory nightmare. Know before you go!
