The Transportation Security Administration publishes a list of prohibited items that runs to hundreds of entries, but what doesn’t make the headlines is how many confiscations happen to experienced travelers who genuinely believed they were following the rules. In 2025, TSA officers discovered over 7,000 firearms in carry-on luggage alone — nearly all of which the owners claimed to have forgotten were there. The rule confusion extends far beyond firearms to items most travelers never even think about.

Items That Keep Surprising Frequent Flyers at TSA Checkpoints

Lithium Battery Power Banks — The New Checkpoint Problem

Power banks are now one of the most common confiscated items at TSA checkpoints, and the rules are more specific than most travelers realize. Power banks must be in your carry-on, not checked baggage — always. But the capacity limit matters: power banks over 100Wh require airline approval, and those over 160Wh are prohibited entirely on passenger aircraft. Most consumer power banks are fine, but the high-capacity models marketed for laptop charging and camping frequently exceed these limits. If the watt-hour rating isn’t printed on the device, TSA officers have discretion — and they frequently exercise it by confiscating the device.

Snow Globes

Snow globes are subject to the 3-1-1 liquid rule, which surprises almost everyone who tries to bring one back from a trip. If the snow globe is larger than 3.4 ounces (the volume of liquid inside is what matters), it must be checked. Most decorative snow globes contain more than 3.4 ounces of liquid. TSA data consistently shows snow globes among the top holiday-season confiscations.

Gel Ice Packs and Reusable Ice

Gel ice packs are treated as liquids by TSA when not fully frozen solid. A gel pack that has any give to it — any gel consistency — fails the 3-1-1 rule. The exception is for medically necessary items and breast milk cooling, which have specific exemptions. Travelers with food they’re trying to keep cold frequently get stopped here. Hard-sided ice packs that are completely solid frozen pass through; anything with gel softness does not.

Peanut Butter

This one genuinely surprises people every time. Peanut butter is classified as a liquid/gel by TSA because of its consistency, and a standard jar of Jif is not making it through the checkpoint in your carry-on. Single-serve packets (under 3.4 ounces) are fine. Jars go in checked baggage or get left at the checkpoint.

Certain Sporting Goods

• Baseball bats: Prohibited in carry-on; must be checked
• Golf clubs: Must be checked
• Ski poles: Must be checked
• Fishing rods: Allowed carry-on at TSA officer discretion — yes, this is actually the rule
• Paracord and rope: Allowed, but may be flagged for inspection if excessive quantity

What Changed in 2026

In 2026, TSA increased enforcement on power bank wattage compliance following several incidents on international flights involving battery fires. Expect closer scrutiny of high-capacity batteries. Additionally, TSA PreCheck lanes at several major airports began using updated imaging technology that more reliably identifies liquid containers regardless of shape — meaning some items that previously slipped through as solid are now being flagged. The practical effect: travelers are seeing more secondary screening of food items in PreCheck lanes than in previous years.

The Rule Travelers Get Wrong Most Often

“If I’ve brought it before, it’s fine” — this is the assumption that gets experienced travelers in trouble. TSA officer discretion is real, enforcement varies by airport and time of day, and rule updates happen without much publicity. The TSA website has a searchable “Can I Bring?” tool that takes 10 seconds to use. It’s worth checking before you pack anything you’re uncertain about, regardless of how many times you’ve flown before.
