Travelers Face New TSA Warnings and Rules at U.S. Airports: What You Need to Know in 2025
As the busy summer travel season kicks off, the Transportation Security Administration (TSA) has issued several important updates that affect millions of people passing through airports across the United States 🇺🇸. These changes include a strong warning about using public USB charging ports, strict enforcement of the REAL ID requirement for domestic flights, and tighter rules on lithium batteries and power banks. With record numbers of travelers expected during Memorial Day week and beyond, understanding these new rules is essential for anyone flying within the United States 🇺🇸.
Here’s what you need to know about the latest TSA updates, why they matter, and how they could impact your next trip.
TSA Warns Against Using Public USB Charging Ports
On May 25, 2025, the TSA issued a major warning to all airport travelers: Do not use public USB charging ports in airport terminals. This warning comes in response to a growing cybersecurity threat known as “juice jacking.” Juice jacking happens when hackers use compromised USB charging stations to install harmful software (malware) on your device or steal your personal data.
Why Is This Warning Important?
Airports are busy places where people often need to charge their phones, tablets, or laptops. Many travelers plug their devices into public USB charging ports without thinking twice. However, these ports can be tampered with by criminals who want to access your personal information or infect your device with malware.
How Does Juice Jacking Work?
- Hackers secretly modify public USB charging ports or cables.
- When you plug your device into a compromised port, malware can be installed without your knowledge.
- This malware can steal passwords, credit card numbers, or other sensitive data.
- In some cases, hackers can even take control of your device.
What Should Travelers Do Instead?
To protect yourself from juice jacking, the TSA recommends:
- Use your own charger and plug it into a regular electrical outlet.
- Carry a portable power bank (but make sure it meets TSA rules—see below).
- Avoid using public USB charging ports in airports, hotels, or other public places.
If you must use a public charging station, consider using a “USB data blocker” device, which allows power to flow but blocks data transfer. However, the safest option is always to use your own charger and a wall outlet.
Strict REAL ID Enforcement Now in Effect
Starting May 7, 2025, the TSA began strictly enforcing the REAL ID requirement for all domestic air travel in the United States 🇺🇸. This means that every passenger aged 18 or older must show a REAL ID-compliant driver’s license or another acceptable form of identification at airport security checkpoints.
What Is REAL ID?
REAL ID is a type of driver’s license or state ID card that meets higher security standards set by the federal government. These IDs have a special mark, such as a star, in the upper corner. The goal is to make it harder for people to use fake IDs and to improve airport security.
Who Needs REAL ID?
- All travelers aged 18 and older flying within the United States 🇺🇸 must have a REAL ID-compliant license or another approved ID.
- Children under 18 do not need identification when traveling with an adult, but the adult must have proper ID.
What If You Don’t Have a REAL ID?
If you do not have a REAL ID-compliant license, you can use another form of identification accepted by the TSA, such as:
- A valid U.S. passport
- A DHS trusted traveler card (like Global Entry, NEXUS, or SENTRI)
- A U.S. military ID
- A permanent resident card (Green Card)
- Other federally recognized documents
You can find the full list of acceptable IDs on the official TSA website.
How Many People Are Complying?
According to the TSA, about 93% of passengers are already presenting REAL ID-compliant identification at checkpoints. However, that still leaves millions of travelers at risk of being turned away if they show up without the right ID.
What Happens If You Don’t Have the Right ID?
If you arrive at the airport without a REAL ID or another accepted form of identification, you will not be allowed to pass through security or board your flight. The TSA may offer a secondary screening process, but this is not guaranteed and can cause long delays.
How to Get a REAL ID
To get a REAL ID, visit your local Department of Motor Vehicles (DMV) office with the required documents, such as proof of identity, Social Security number, and two proofs of address. Processing times can vary, so it’s best to apply well before your next trip.
TSA Cracks Down on Lithium Batteries and Power Banks
In addition to new ID rules, the TSA is now more strictly enforcing regulations on lithium-ion batteries and portable power banks. These batteries are common in phones, laptops, tablets, and portable chargers, but they can pose a fire risk if not handled properly.
What Are the New Rules?
- All lithium-ion batteries and power banks must be under 100 watt-hours (Wh).
- Batteries must be clearly labeled with their capacity.
- You must carry these batteries in your carry-on baggage, not in checked luggage.
- Unlabeled or oversized batteries may be confiscated at security checkpoints.
- Bringing multiple battery-powered devices may trigger extra screening.
Why Is the TSA Enforcing These Rules?
Lithium batteries can overheat or catch fire if damaged or short-circuited. By limiting the size and number of batteries, the TSA aims to reduce the risk of fires on airplanes.
What Should Travelers Do?
- Check your devices and power banks before you travel. Make sure each battery is under 100 Wh and clearly labeled.
- Pack all spare batteries and power banks in your carry-on bag. Do not put them in checked luggage.
- If your battery is not labeled or is too large, leave it at home. The TSA may take it away if it does not meet the rules.
Record Memorial Day Travel Volumes Expected
From May 22 to May 28, 2025, the TSA expects to screen about 18 million passengers and crew—one of the busiest travel periods on record. This surge is likely to continue through the summer, with more people flying for vacations, family visits, and business trips.
What Does This Mean for Travelers?
- Longer lines at security checkpoints
- More crowded terminals and gates
- Higher chance of delays, especially if you don’t have the right documents or your bags need extra screening
How to Prepare for Busy Travel Periods
- Arrive at the airport at least two hours before your flight for domestic travel, and three hours for international flights.
- Have your REAL ID or other accepted ID ready before you reach the security checkpoint.
- Pack smart: Follow TSA rules for batteries, liquids, and electronics to avoid delays.
- Charge your devices before leaving home and bring your own charger to avoid using public USB charging ports.
Background: Why Are These Changes Happening Now?
The TSA’s new warnings and stricter rules are part of a larger effort to keep travelers safe in a changing world. As technology advances, so do the methods used by criminals and hackers. Juice jacking is just one example of how cyber threats can affect people in public places like airports.
At the same time, the REAL ID program has been in the works for years, with several delays before finally taking effect in May 2025. The goal is to make it harder for people to use fake IDs and to strengthen airport security.
Lithium battery rules have also become more important as more people carry multiple electronic devices and portable chargers. Fires caused by batteries are rare but can be very dangerous on airplanes.
