TSA suggests leaving at home or packing in checked baggage the following items: maple syrup, oils and vinegars, perfume, salad dressing, salsa, sauces, snowglobes, soups, wine, liquor, beer, cranberry sauce, cologne, creamy dips or spreads, cheeses, peanut butter, gift baskets with food items, gravy, jams, jellies and lotions. These items may present explosive dangers or appear to explosives.
After a series of explosive tests, Homeland Security and TSA determined that liquids, aerosols and gels are to be allowed through security, but only in safe quantities. To make the concept simple for travelers, it has been broken down to the 3-1-1 moniker. Three stands for 3.4 ounce containers as the size limit and one stand for one quart-sized bag for all the liquids and a limit of one bag for each passenger. Size exceptions are considered for items like medications, baby formula and breast milk, but such items must be declared at the security checkpoint.
As of June 21, 2008, TSA reports that all passengers of age 18 and over are "required to show a U.S. federal or state-issued photo ID that contains the following: name, date of birth, gender, expiration date and a tamper-resistant feature in order to be allowed to go through the checkpoint and onto their flight." Acceptable IDs include U.S. passport, U.S. passport card, DHS "Trusted Traveler" cards (NEXUS, SENTRI, FAST), U.S. Military ID (active duty or retired military and their dependents, and DOD civilians), Permanent Resident Card, Border Crossing Card, DHS-designated enhanced driver's license, Drivers Licenses or other state photo identity cards issued by Department of Motor Vehicles, Native American Tribal Photo ID, airline or airport-issued ID, foreign government-issued passport, Canadian provincial driver's license or Indian and Northern Affairs Canada (INAC) card or Transportation Worker Identification Credential (TWIC).
Due to safety concerns, TSA and the Department of Homeland Security have outlined a number of items that airline passengers are prohibited from carrying onto a plane. These items include sharp objects, like box cutters, knives and scissors; sporting goods, like baseball bats, pool cues and spear guns; guns and firearms of any kind; tools, such as axes, hatches and drills; martial arts and self-defense weapons like throwing stars, billy clubs and stun guns; explosive materials and disabling chemicals like bleach, tear gas and spray paint.
