What are the size restrictions for liquids in carry-on bags?

The Transportation Security Administration has established specific guidelines regarding the transportation of liquids in carry-on bags to ensure the safety of all passengers. According to these guidelines, liquids must be contained within containers that do not exceed 3.4 ounces, which is equivalent to 100 milliliters. Each passenger is permitted to carry multiple containers, but all liquids must fit comfortably within a single quart-sized, clear, resealable plastic bag. This plastic bag needs to be presented separately during the security screening process at the airport. It is important to note that the total volume of liquids in your carry-on should not exceed what can be stored in this quart-sized bag. The regulation includes various types of liquids, such as water, beverages, perfumes, lotions, creams, and gels. There are certain exceptions to these rules, particularly for medications, baby formula, and food items that may exceed the volume limit. However, these exceptions still require passengers to inform the TSA officers at the security checkpoint for proper screening and handling. Overall, it is advisable for travelers to familiarize themselves with these requirements before heading to the airport to ensure a smooth security process.
