TSA rules will be more enforced than ever, and high-tech screening equipment in 2025-2026 will mean there should be more planning than ever.

Nobody wants to be deceived into thinking that they are aware of what they can and cannot bring with them on board an aircraft, only to find out that the pocketknife they left in their pocket, or the liquid that is more than the approved volume, or the battery pack they had forgotten, cost them the hassle.

Why Airport Security Screening Is Stricter in 2025-26

Security processes at the airports have developed over the past few years. TSA screening now uses:

• Advanced imaging scanners

• Automated tray systems

• AI-based threat detection

• Improved liquid and battery inspection.

Although technology enhances the screening process of compliant travelers, it also detects banned merchandise at a faster rate than previously. Borderline cases no longer receive leniency from the security officers.

This implies that passengers are expected to carry out comprehensive baggage checks before they get to the airport.

The TSA Packing Checklist Mindset

Before packing into the five key items, it is useful to be in the TSA packing checklist mentality.

Ask yourself:

• Would this object be of concern, provided it is scanned?

• Does it have a sharp edge? Is it liquid or battery-operated?

• Is the question of size or quantity doubted?

• Are there new rules that I have not been on before?

• In case the answer is that it is possibly so, it is worth reconsideration.

1. Liquids, Gels, and Sprays

The most prevalent and common cause of delay at the security checkpoint at an airport is liquids.

TSA Rule (2025–26)

Carry-on liquid bags have to be in accordance with the 3-1-1 rule:

• The containers should not be more than 100 ml (3.4 oz).

• Every container should be included in a single clear quart-size bag.

• One bag per passenger

• Top 12 Blunders tourists commit.

• Bring full-size shampoo in case.

• Leaving liquids in pocket side pockets.

• Distributing liquid makeup or sunscreen.

• Giving the location of duty-free a free pass.

Real Packing Example

A tourist will carry a 200 ml bottle of sunscreen in his or her carry-on.

TSA discards the bottle during the screening.

Better approach:

• Pour liquids into medium-sized containers.

• Position the bag of liquid at the top of your baggage.

• Take it out and put it into the scanner.

• Fluids are difficult to detect and simple to remedy.

2. Sharp Objects and Tools

A lot of travelers have sharp things but are unaware of their presence.

Items Not Allowed in Carry-On:

• Pocket knives

• Box cutters

• Razor blades (loose)

• Scissors over 4 inches

• Nail clippers with files

• Multi-tools

• Sewing needles (without medical purpose).

Real Packing Example

Somebody forgets to leave a small Swiss Army knife in his/her bag pack.

TSA confiscates the knife

Better approach:

• Take out all your pockets of the bag.

• Check side compartments

• Place sharp items into the checked baggage.

One of the most common things that are being confiscated all over the world is sharp objects.

3. Electronics and Batteries

Batteries are highly scrutinized in the security checks at airports because of possible fires.

TSA Battery Rules 2025–26

• Li batteries should be in carry-on bags.

• Power banks must be under 100Wh

• Destroying batteries is forbidden.

• E-cigarettes can be carried on only.

Common Mistakes

• Carrying power banks in baggage.

• Bringing the huge battery packs.

• Carrying battered charging cables.

• Leaving spare batteries in bags.

Real Packing Example

A tourist carries a 150Wh power bank in his/her bag.

TSA removes the device

Better approach:

• Capacity of the check battery before packing.

• Pack only the necessary electronics.

• Plug adaptors should always be in place.

4. Food and Organic Items

Many travelers are puzzled by food regulations since they allow solid food but not liquids.

What TSA Allows

• Sandwiches

• Snacks

• Fruits

• Cookies

• Chips

• Bread

What Causes Problems

• Peanut butter

• Yogurt

• Dips

• Sauces

• Soups

• Creamy spreads

This can be counted as liquids or gels.

Real Packing Example

TSA confiscates the jar

Better approach:

• Choose solid snacks

• Avoid spreads

Make food available for inspection.

5. Documents and Personal Items

Although it is not forbidden, documents that are lost or misplaced may slow down the screening process.

Double-Check These Items

• Boarding pass

• Government ID or passport

• Visa (if applicable)

• Medical documentation

• Child travel documents

• Special permits

Real Packing Example

The customer checks the bag with a passport.

Slow and tense at the check-in.

Better approach:
