Traveling within the United States involves a different set of documents and preparations than international trips. This checklist covers the identification you need for flights, the steps for check-in and baggage, what to have for driving or renting a car, how to handle lodging and time zones, and the essentials to pack. By following this guide, you can move through security, rental counters, and hotel check-ins with confidence.
ID for Domestic Flights
For domestic air travel, you need a valid, TSA-accepted form of identification. The most common option is a REAL ID-compliant driver’s license or state ID. Starting May 7, 2025, every air traveler 18 and older must present a REAL ID-compliant license or another acceptable form of ID to fly within the U.S. Check your state’s department of motor vehicles website to see if your current license has the REAL ID star symbol. If it does not, you can upgrade before your trip.
Other TSA-accepted IDs for domestic flights include a valid U.S. passport, a U.S. passport card, a DHS trusted traveler card (Global Entry, NEXUS, SENTRI, FAST), a military ID, or a permanent resident card. If you arrive at the airport without acceptable ID, TSA may try to verify your identity through an alternative process, which takes extra time, may involve a fee, and is not guaranteed. Check the TSA website for the current procedure. Bring your ID in your carry-on, not checked luggage, because you need it at the security checkpoint.
For general travel preparation, see the Travel Checklist for a broader overview of what to arrange before any trip.
Flights and Bags
Check-In and Boarding Pass
Online check-in typically opens 24 hours before departure, though some airlines open it earlier. You can use a mobile boarding pass on your phone or print a paper copy at the airport kiosk. Have your boarding pass and ID ready at the security checkpoint and at the gate. If you check bags, you will need your ID at the airline counter.
Carry-On and Checked Baggage Rules
Follow TSA guidelines for carry-on items. Liquids, aerosols, and gels in your carry-on must be in containers of 3.4 ounces (100 milliliters) or less and placed in a single quart-sized clear plastic bag. One bag per passenger. This is the TSA liquids rule; check the official TSA liquids rule page for current details. For all other items, use the TSA What Can I Bring tool before packing.
For checked bags, most airlines have size and weight limits. A common rule of thumb is a checked bag should not exceed 50 pounds (23 kilograms) and 62 linear inches (length + width + height). Overweight or oversized bags incur fees. To avoid surprises at the airport, use a luggage scale to weigh your bag at home.
Lithium batteries must be carried in your carry-on, not checked. This includes power banks, spare batteries for cameras, and e-cigarettes. Check the FAA PackSafe lithium batteries page for specific limits on battery sizes.
Baggage Claim
After your flight, go to the baggage claim area for your airline and flight number. Keep your baggage claim tag until you have your bag. If your bag is delayed or damaged, report it to the airline’s baggage office immediately before leaving the airport.
Driving and Rental Cars
Documents for Driving Your Own Car
If you are driving to your destination, carry your valid driver’s license, vehicle registration, and proof of insurance. Keep these documents in your wallet or a glove compartment folder, not loose in the car. For interstate travel, your U.S. license is valid in all states, but some states have specific requirements for out-of-state drivers. Check the Ready.gov car safety page for emergency kit suggestions and vehicle preparation tips.
Rental Car Requirements
To rent a car in the United States, you typically need a valid driver’s license and a major credit card in your name; you will also need to decide how the car will be insured, whether through your own policy, a credit card benefit, or the rental company’s coverage. Most rental companies require the renter to be at least 21 years old, and drivers under 25 often pay a young driver surcharge. Some companies accept debit cards, but they may place a larger hold on funds or require a credit check. Bring your own car insurance card or purchase the rental company’s collision damage waiver. If you have a credit card that offers rental car insurance, check the terms and bring the benefit guide.
When picking up the car, inspect it for existing damage and have the rental agent note it on the contract. Take photos of the car’s exterior and interior before driving off. Confirm the fuel policy—most rentals require you to return the car with a full tank.
Road Trip Essentials
For longer drives, prepare a roadside emergency kit with jumper cables, a flashlight, a first-aid kit, water, and non-perishable snacks. Plan your route and identify rest stops, gas stations, and hotels along the way. For a full list of what to bring on a road trip, see the Road Trip Essentials guide.
Lodging and Time Zones
Lodging Reservations and Check-In
Book your hotel, motel, or vacation rental in advance, especially during peak travel seasons. Carry a printed or digital copy of your reservation confirmation, including the check-in time, address, and cancellation policy. Most hotels require a credit card for incidentals at check-in. If you arrive after the front desk closes, call ahead to arrange late check-in or a lockbox code.
For vacation rentals, read the house rules, check-in instructions, and amenity details before you arrive. Have the host’s contact information handy in case of issues.
Time Zones
The continental United States spans four time zones: Eastern, Central, Mountain, and Pacific. Alaska and Hawaii have their own zones. When traveling across time zones, update your phone, watch, and any travel alarm clock to the local time as soon as you arrive. Double-check meeting times, tour bookings, and flight departure times—airlines always list departure and arrival times in local time. If you are driving across a time zone boundary, be aware that the time changes abruptly, which can affect rest stop hours and hotel check-in windows.
Packing
Clothing and Footwear
Pack versatile clothing that layers. Check the weather forecast for your destination and pack accordingly. Bring one pair of comfortable walking shoes for sightseeing and one dressier pair if needed. Include a light jacket or sweater even in warm climates, as indoor air conditioning can be chilly. For trips that include both city and outdoor activities, pack a mix of casual and slightly dressy outfits.
Toiletries and Medications
Pack travel-sized toiletries in your carry-on: shampoo, conditioner, body wash, toothpaste, and deodorant. If you need larger quantities, put them in checked luggage. Bring any prescription medications in their original bottles with your name and dosage. Carry enough medication for the entire trip plus a few extra days in case of delays. Over-the-counter basics like pain relievers, antacids, and antihistamines are helpful to have on hand.
Electronics and Chargers
Bring your phone, laptop or tablet, and their chargers. A portable power bank is useful for long days out. Pack a universal power strip if you have multiple devices, as many hotel rooms have limited outlets. Keep chargers and cables in your carry-on so you can charge devices during layovers.
Documents and Money
Carry your ID, boarding pass, hotel confirmations, and rental car reservation in a secure travel wallet or pouch. Bring a credit card and a debit card from different banks in case one is lost or frozen. Keep some cash for small purchases, tolls, or tips. Make photocopies or digital scans of your ID and credit cards and store them separately from the originals.
Miscellaneous Essentials
Pack a reusable water bottle to fill after security, a small umbrella or rain jacket, and a reusable shopping bag for souvenirs. If you are flying, remember to put any sharp objects, tools, or sports equipment in checked luggage. For a complete packing list for any trip, refer to the Airport Essentials guide.
