At Philadelphia International Airport, like most airports worldwide, travelers are subject to the Transportation Security Administration's regulations regarding liquids. Generally, passengers are allowed to bring liquids in containers that hold no more than 3.4 ounces, which must all fit within a single quart-sized clear plastic bag. It is important to note that any liquids exceeding this limit must be packed in checked baggage, as they will not be permitted through the security checkpoint. Exceptions exist for medications, baby formula, and breast milk, which may be carried in larger quantities, but travelers are advised to inform security personnel about these items for proper screening. For the most current information regarding security policies and what to expect at the airport, travelers may want to refer to the official Philadelphia International Airport website.
