Three ounces of liquid, gel or aerosol in a larger container, most times, is unacceptable. Obtaining a complete list of restrictions prior to your trip will help to smooth the process out. The system really is quite simple. When you reach the security checkpoint, the clear plastic bag must be separated from the rest of your luggage to be examined by airport personnel. Each traveler is allowed only one bag, so plan accordingly. It has been recently discussed in the media whether one is able to bring liquids on an airplane, or not. These items are baby formula, juice or breast milk for infants and toddlers. If you arrive with the wrong size bottle, the airport will provide one for at a fixed price. You can also bring items that are liquid or gel based that are meant to augment the body for medical or cosmetic reasons. For many airlines you may check as many bags as you would like, but if you go over the weight limit you will be fined heavily. Airlines also charge a fee if your luggage exceeds their allowed weight limit. There are exceptions to the rules. Packing is one of the trickiest aspects of reaching ones destination by flight.
A variety of essential items are allowed to be carried in containers larger than three ounces. The same rule applies to liquids, gels and aerosols: they must all be in containers that hold three ounces or less. If you have a disability or medical condition that requires you to have water, juice, gels or liquid nutrition you may carry those with you as well. They cannot share the same bag. In many cases, you must also declare that you have these items with the security personnel at the checkpoint. Next time you are flying, make sure you know what you are able to bring to your flight. Due to these rules changing often, check with your airport prior to your flight to ensure a stress-free trip. Your final step will be to present these items for additional inspection at the x-ray machine. A final exception is made for passengers that require gels or frozen liquids in order to cool medical or disability related items. The container must be three ounces or smaller. Sandwich bags that you fold will not be allowed. Any life support or life sustaining liquids can be carried in larger containers as well. This is the main reason why purchasing a 3 ounce bottle prior to arriving at the airport is beneficial to both being on-time for your flight, and saving money. Go to a grocery or drug store and purchase a few three ounce clear plastic containers.
