Step up to the security line with confidence—no more last-minute tug-of-war over your liquids, gadgets, or snacks.
In the summer of 2024, TSA screened a record 2.99 million passengers in a single day—a sign that airport checkpoints have never been busier. Yet, millions still face delays or confiscations for simple packing mistakes.
From the 3-1-1 liquids rule to lithium-battery limits and CT-scanner upgrades, this guide decodes every rule you need to know in 2025 to keep your carry-on compliant and your journey stress-free.
Why Carry-On Rules Matter
Below is an expert breakdown of why strict carry-on security rules are essential—for safeguarding everyone aboard and avoiding costly screening delays or penalties.
In essence, standardized carry-on regulations remove potential threats before boarding, leverage advanced imaging to speed throughput, and maintain a predictable, efficient screening process. Ignoring these rules not only risks longer waits and bag pull-asides but also immediate confiscation of forbidden items and civil fines that can range from hundreds to tens of thousands of dollars.
Security Rationale
Carry-on rules exist first and foremost to keep dangerous items out of the cabin, reducing fire, chemical or weapon risks before boarding begins.
- Carry-on regulations classify items like flammable gels, aerosols, and sharp objects so that X-ray systems and officers can reliably spot and remove them at security checkpoints.
- Advanced screening technologies, such as Computed Tomography (CT) scanners, generate 3D bag images that greatly improve threat detection accuracy and slash the need for manual bag searches.
- In FY 2022, TSA deployed 243 CT X-ray scanners nationwide to boost throughput and enhance security effectiveness across busy U.S. airports.
- Standardized measures like the 3-1-1 liquids rule (3.4 oz containers in a 1-quart bag) streamline what passengers pack, enabling officers to spot anomalies faster and keep lines moving.
Consequences of Non-Compliance
Failing to follow carry-on rules carries immediate and far-reaching impacts for you—and everyone in line behind you.
- Secondary Screening Delays
Bags with prohibited items are pulled aside for additional inspection, often adding 10–20 minutes per passenger and increasing stress or risking missed connections. - Confiscation of Prohibited Items
Any forbidden object—whether a large liquid container, oversized tool, or undeclared lithium battery—is seized on the spot, with no opportunity for recovery during travel. - Civil Penalties
TSA’s civil enforcement can impose fines up to $17,062 per violation, with repeat offenses drawing even higher penalties. - Specific Violation Fines
- Flammable gels/creams over 3.4 oz: $390–$2,250
- Blasting caps or >10 oz of gunpowder: $8,960–$14,950
- Firearm in carry-on: up to $15,000 (first offense), plus loss of TSA PreCheck for five years and possible law enforcement involvement
- Real-World Stakes
In 2024 alone, TSA officers intercepted 6,678 firearms at security checkpoints—proof that rigorous carry-on screening is preventing dangerous items from reaching aircraft cabins. - Collective Impact
Beyond individual penalties, non-compliance creates bottlenecks that slow the entire line. Respecting carry-on rules is both a personal duty and a community consideration.
Civil Penalties at a Glance
| Violation Type | Penalty Range | Additional Consequence |
|---|---|---|
| Flammable gels > 3.4 oz | $390–$2,250 | Item confiscation |
| Any prohibited item | Up to $17,062 | Repeat violations carry steeper fines |
| Firearm in carry-on | Up to $15,000 | Loss of PreCheck for 5 yrs; possible arrest |
By understanding the security rationale and the serious consequences of non-compliance, you can pack smarter, speed through TSA screening, and avoid fines or flight disruptions.
2025 Regulatory Landscape
Below is an expert overview of the 2025 regulatory landscape, highlighting how U.S. carry-on rules compare with international standards and the major policy updates travelers need to know this year.
In 2025, carry-on regulations remain globally harmonized around core safety measures—100 ml liquid limits (3-1-1), battery watt-hour caps, and advanced imaging screening—yet regionally vary in container sizes, CT-scanner deployment, and carrier-specific baggage allowances. The TSA permits up to two spare lithium-ion batteries of 101–160 Wh with airline approval, while IATA guidelines mirror these caps and add recommended state-of-charge limits effective January 1, 2025. Meanwhile, EU member states are rolling out CT scanners to allow 2 L of liquids in a single sealed bag—though the UK extended full implementation until June 2025—and airlines like Air Canada have introduced new fare-based carry-on bans.
TSA vs. International Authorities
Key Similarities
- Liquid Limits (3-1-1 Rule): Both TSA and bodies like ICAO/IATA enforce containers ≤ 100 ml in a single quart-sized bag per passenger, simplifying threat detection and line throughput.
- Battery Watt-Hour Caps: Carry-on batteries must not exceed 100 Wh, with spare batteries of 101–160 Wh allowed under defined limits—up to two spares per person—with items over 160 Wh restricted to cargo transport.
- Prohibited Items: Sharp objects, self-defense gear, and flammable aerosols are universally banned in carry-on across TSA, EU/EASA, UK CAA, and other national authorities.
Key Differences
| Aspect | TSA (U.S.) | International (IATA/EU/UK) |
|---|---|---|
| Dimensional Guidelines | Defers to airlines (e.g., average 22 × 14 × 9 in) | Recommends 56 × 45 × 25 cm (22 × 18 × 10 in); Canada: 55 × 40 × 23 cm |
| Battery Carry Rules | ≤ 100 Wh unlimited; 101–160 Wh (max two spares with approval) | Same base limits; IATA caps spares at 20 under 100 Wh, two spares 101–160 Wh; > 160 Wh cargo only |
| Liquid Screening Tech | Standard X-ray at most airports; phased CT-scanner rollout | EU rolled out CT scanners Sept 1, 2024 (two-liter rule pilots); UK full CT rollout now delayed to June 2025 |
| Special-Need Exceptions | TSA Cares for medical devices; documented meds allowed | ICAO/IATA also exempt prescription meds, baby food under inspection protocols |
Recent Policy Updates
What Changed in 2025
| Update | Effective Date | Details |
|---|---|---|
| EU Two-Liter Rule via CT Scanners | Sept 1, 2024–mid 2025 | Select EU airports began using CT scanners to allow up to 2 L of liquids in a sealed bag under advanced imaging; UK extended deadline to implement new scanners until June 2025 |
| IATA State-of-Charge Recommendation | Jan 1, 2025 | Recommended that lithium-ion batteries in equipment be offered at ≤ 30% state of charge to reduce thermal-runaway risk; mandatory from Jan 1, 2026 |
| Air Canada Basic Economy Carry-On Ban | Jan 3, 2025 | Basic-fare tickets no longer include standard carry-on allowance—passengers limited to a personal item only |
| TSA & DHS Next-Gen Screening Push | Throughout 2025 | Joint TSA/DHS initiative expanding next-generation CT X-ray and AI-driven screening technology to improve detection and speed traveler throughput |
| TSA Spare Battery Clarification | Late 2024 Update | Reaffirmed policy: passengers may carry up to two spare lithium-ion batteries (101–160 Wh) in carry-on with airline approval; batteries ≥ 160 Wh remain prohibited in cabin |
These aligned yet nuanced regulations underscore the importance of checking both TSA guidance and your airline’s specific policy before flying.
Liquids, Gels & Aerosols
Below is a practical, expert-led dive into Liquids, Gels & Aerosols for 2025 travel—explaining the 3-1-1 rule, detailing vital exceptions, and sharing pro packing hacks. By mastering these guidelines, you’ll breeze through security and keep your favorite toiletries at hand.
The 3-1-1 Rule Explained
Under the TSA’s 3-1-1 rule, each traveler may carry liquids, gels and aerosols in containers no larger than 3.4 ounces (100 milliliters), all fitting into a single quart-sized (≈ 0.95 L) clear, resealable bag—one bag per passenger.
- 3 = containers ≤ 3.4 oz (100 ml)
- 1 = one quart-size, clear, zip-top bag
- 1 = one bag per traveler
At screening, you must remove this bag from your carry-on to place it in a bin for separate X-ray inspection, which speeds up conveyor throughput and reduces manual checks.
Exceptions & Exemptions
While the 3-1-1 rule is strict, critical items get a pass—just declare them at the checkpoint:
| Item Type | Allowance | Screening Notes |
|---|---|---|
| Medications | No size limit if “medically necessary”; reasonable quantity | Must be declared; subject to additional inspection |
| Baby Formula/Milk | No size limit; includes breast milk and juice for infants | Remove from bag; screened separately |
| Duty-Free Liquids | > 3.4 oz if in sealed, tamper-evident (SED) bag with receipt | SED bag must remain sealed; any alarm triggers manual check |
These exemptions ensure essential items—life-saving meds, infant nutrition, and souvenirs—aren’t left behind, while still maintaining secure screening standards.
Packing Tips & Tricks
- Invest in Pre-Measured, Leak-Proof Bottles
- Use durable, silicone 3 oz travel bottles—they’re lightweight, flexible, and certified for carry-on.
- Brands like Gemice offer TSA-approved sets with secure caps to prevent spills.
- Label Clearly & Group Strategically
- Mark each bottle with its contents (e.g., “shampoo,” “sunscreen”) using waterproof labels—saves time at security and keeps you organized.
- Pack bottles upright in the center of your quart bag to minimize pressure on seals.
- Use Free Airport Bags & Pre-Cut Zip-Tops
- Many U.S. airports giveaway quart bags at security entrances—grab one if you forgot yours.
- Pre-cut gallon-size zip-tops (slightly larger) can double as a shock-absorbing layer around your quart bag.
- Freeze Liquids as Ice Packs
- Fill an extra empty bottle halfway and freeze it; use it as an ice pack for snacks or skincare, then stow as a 3 oz container once thawed.
By mastering the 3-1-1 rule, leveraging exemptions, and packing smart with the tips above, you’ll keep your essentials accessible—and security lines moving—every time you fly. Don’t forget to bookmark this guide and download our printable carry-on checklist before your next trip!
Electronics & Batteries
Below is an expert, travel-pro breakdown of Electronics & Batteries for 2025—what you need to know to sail through TSA checkpoints and keep your devices powered safely.
In 2025, all electronics larger than a cell phone—laptops, tablets, e-readers—must be removed from carry-on bags and X-rayed separately to provide clear 3D images for CT scanners and reduce manual inspections. Spare lithium-ion batteries and power banks are strictly carry-on only, with no checked-baggage exceptions, and must be individually protected against short-circuit by keeping them in original packaging, dedicated battery cases, or insulated pouches. Standard lithium-ion cells under 100 Wh require no airline approval; units of 101–160 Wh are limited to two spares per passenger with explicit airline approval; anything over 160 Wh is prohibited from both carry-on and checked bags.
Standard Electronics
Travelers must remove personal electronics larger than a cell phone—laptops, tablets, e-readers—from carry-on bags and place them alone into security bins for X-ray screening. This separation gives TSA officers unobstructed, high-resolution views to spot concealed threats, reducing the need for time-consuming manual checks. In TSA PreCheck lanes, enrolled passengers keep these devices in their bags, cutting average screening times to under 10 minutes versus 30 minutes in standard lanes.
Spare Batteries & Power Banks
- Carry-On Only: Portable chargers, power banks, and all spare lithium-ion or lithium-metal batteries are prohibited in checked luggage and must remain with you in the cabin.
- Protection Required: Each spare battery must be individually protected to prevent short-circuits—keep them in original packaging, specialized battery cases, or insulated pouches.
- Capacity Limits: Battery TypeLimitCarry-OnAirline Approval Required?Lithium-ion ≤ 100 WhUp to 100 WhYesNoLithium-ion 101–160 Wh101–160 WhYes (2)YesLithium-ion > 160 WhOver 160 WhNoN/ALithium-metal ≤ 2 g (content)Up to 2 gYesNoLithium-metal > 2 gOver 2 gNoN/A
TSA Screening Insights
- Bin Placement: Always place each device or spare battery bin – separately – with nothing on top or underneath. This simple step produces a clearer X-ray image and drastically cuts down secondary inspections.
- Power-On Requests: If asked, power on your device. A dead battery can trigger manual inspection or denial of boarding for security reasons.
- Signal Cables & Accessories: Wrap cords and tuck accessories inside your carry-on. Excess clutter can hide prohibited items and slow screening.
- Know Before You Go: Check both TSA’s “What Can I Bring?” page and your airline’s website for any stricter rules or size restrictions on electronics and batteries—policies can vary by carrier.
Bottom Line: Pack your electronics for easy removal, stow spare batteries safely in your carry-on, and be prepared to power up on request. These simple steps will keep you compliant, reduce hold-ups at security, and ensure your devices make it to the gate—and beyond—fully charged.
Medical Equipment & Special-Need Items
Below is a travel-expert overview of Medical Equipment & Special-Need Items in your carry-on for 2025. You can bring both prescription and over-the-counter medications beyond the usual 3-1-1 limits—just declare them and label clearly. Insulin pumps and CPAP/BiPAP/APAP devices are fully permitted when you notify TSA; they may remain in their case or, if inseparable, be hand-inspected to protect function. Contact-lens solutions and breast milk are exempt from size caps—declare and screen them separately to avoid delays.
Prescription Medications vs. Over-the-Counter
Travelers may carry prescription medications in amounts exceeding 3.4 oz (100 ml) if they are clearly labeled in their original containers—simply declare them at security and place them in a separate bin for screening. U.S. Customs and Border Protection likewise reminds passengers to travel only with medications prescribed to them by a licensed physician.
Similarly, over-the-counter (OTC) medications (e.g., saline solution, cough syrup) are exempt from the 3-1-1 liquids rule when medically necessary—declare and remove them from your bag to speed screening. TSA’s “Medications (Liquid)” guidance confirms that reasonable quantities of medically necessary gels and aerosols may exceed standard limits when declared.
For travelers with diabetes, the American Diabetes Association notes that diabetes-related supplies—including insulin and test kits—are always allowed once properly screened; just separate them from other items and inform the officer.
Insulin Pumps & CPAP Machines
Insulin pumps and supplies (pens, cartridges, glucose monitors) are permitted in both carry-on and checked bags—just notify the TSA officer, and ensure all insulin is clearly identified. The CDC advises never to pack insulin in checked luggage (risking extreme temperatures) and to keep supplies with you in a cooler or insulated pack.
CPAP, BiPAP, and APAP machines—along with masks and tubing—may remain in their carrying case for X-ray screening; if the device must stay connected to an external power source, you can request a hand-inspection or pat-down instead to avoid damage. UCLA Health clarifies that pumps and continuous glucose monitors can go through metal detectors but may require removal before full-body scanners, with an alternative screening option on request.
Contact-Lens Solutions & Breast Milk
Contact-lens solutions over 3.4 oz are best placed in checked baggage, but medically necessary amounts may be carried in excess of the limit if declared; officers may test or swab samples if the solution alarms. TSA’s broader “Medical” list notes that any medically necessary liquid causing an alarm can be subject to additional inspection or refusal—but declaring it avoids surprises.
Breast milk, formula, and toddler drinks are classified as medically necessary liquids with no size restriction; they need not fit in the quart bag but must be declared and screened separately. Cooling accessories (ice packs, gel packs) are likewise allowed in any quantity to maintain freshness.
Table: Medical Items Screening at a Glance
| Item | Quantity Limits | Declaration Required | Screening Procedure |
|---|---|---|---|
| Prescription Medications | No size limit; original container | Yes | Separate bin; possible manual inspection |
| Over-the-Counter Medications | No size limit if medically necessary | Yes | Declare; separate screening bin |
| Diabetes Supplies (insulin, kits) | No size limit; separate from other items | Yes | X-ray or hand inspection |
| Insulin Pumps & CGMs | No size limit; notify TSA | Yes | May stay on during X-ray; alternative screening available |
| CPAP/BiPAP/APAP Machines | No size limit; carrying case OK | Yes | Case can go through X-ray; hand inspection on request |
| Contact-Lens Solution | Exempt if medically necessary | Yes | Declare; swab or test sample if alarm |
| Breast Milk & Formula | No size limit | Yes | Declare; screened separately; cooling packs allowed |
By labeling clearly, declaring proactively, and knowing your rights, you’ll keep essential medical items within reach and move seamlessly through security—no surprises, no stress.
Food & Beverage Restrictions
In 2025, understanding which foods you can—and can’t—bring aboard is key to a smooth security experience. Solid items like sandwiches and snacks sail through checkpoints without size limits, while soups, sauces and other gel-like foods must obey the 3-1-1 rule (≤ 100 ml per container, 1-liter bag). Internationally, the EU sticks to 100 ml limits in a 1 L bag (with CT-scanner pilots extending to 2 L in some airports), and Middle Eastern carriers grant baby-food and medical exemptions when you show proof. Smart packing—vacuum-sealed snacks, clear containers, pre-labeled portions—keeps freshness and speeds screening.
Solid Foods vs. Liquids
Solid foods—think sandwiches, fruit, granola bars—are allowed in both carry-on and checked luggage without size caps, though regulators may pull bags for a quick look if items clutter the X-ray view. By contrast, liquid or gel foods (soups, sauces, yogurts) fall under the 3-1-1 rule: containers must be ≤ 3.4 oz (100 ml), fit in one quart-sized clear bag, and only one bag per passenger.
| Food Type | Carry-On | Checked Bag | Notes |
|---|---|---|---|
| Solid (sandwiches, snacks) | Yes | Yes | No size limit; may trigger extra screening if cluttered |
| Soups, broths | ≤ 100 ml (3.4 oz) | Any | Must be in quart bag under 3-1-1 |
| Sauces, dips | ≤ 100 ml | Any | Pack in clear bag; seal tightly |
| Yogurts, puddings | ≤ 100 ml | Any | Pre-portion in travel cups |
International Variations
- European Union: Mirrors the 100 ml rule with liquids in a single 1 L bag, applicable at all EU airports plus Norway, Iceland & Switzerland. CT-scanner pilots at select hubs now allow up to 2 L sealed bags—full rollout expected mid-2025.
- Middle East (e.g., Emirates, Etihad): One clear bag per passenger; baby food, breast milk, medical liquids (e.g., special dietary drinks) are exempt when you present proof—officers may open and inspect, but sizes aren’t capped.
- UK & Gulf Carriers: Post-Brexit, UK budget airlines (TUI, easyJet, Ryanair, Jet2) ban meat/dairy into the EU and restrict personal hot drinks or alcohol, though cold foods remain OK. Always check your destination’s customs rules to avoid surprises on arrival.
Packing Hacks
- Vacuum-Sealed Snacks: Lock in flavor and save space—freeze-dried meals and nuts in vacuum pouches are treated as solids, so no 3-1-1 hassle.
- Clear, Resealable Bags & Containers: Use transparent quart bags or slim acrylic tubs for sauces under 100 ml; visibility speeds officer review and cuts down bin pulls.
- Pre-Cut Silicone Reusable Bags: Eco-friendly and leak-proof, these bags flex to fit oddly shaped items and withstand inspection without tears.
- Freeze Liquids as Ice Packs: Partially fill a travel bottle, freeze it, then top off with liquid—acts as a cooling pack and meets the container limit once thawed.
By knowing the fine print on solid vs. liquid foods, respecting international nuances, and mastering these packing workarounds, you’ll stay compliant, streamline screening, and keep your favorite snacks at hand.
