Can You Bring RELX On A Plane? | Carry-On Only

You’re through the check-in counter, bag tagged, boarding pass in hand. Then your hand goes to your pocket and you remember the RELX. Will security flag it? Can it fly in the hold, or does it need a seat with you?

The honest answer is straightforward: your RELX is allowed on the plane, but only in your carry-on. The lithium-ion battery inside is why checked luggage is off‑limits. That rule comes from the FAA and TSA, not from airline preference, and it applies to every vaping device, pod mod, or e‑cigarette.

TSA Rules For Vaping Devices

The Transportation Security Administration is clear: electronic smoking devices, including RELX vapes, are permitted only in carry-on baggage. They are prohibited in checked luggage entirely. This isn’t a suggestion — it’s a federal regulation.

Passengers must also take measures to prevent accidental activation during transport. Turning the device off or removing the battery counts. The TSA has a specific page on TSA carry-on rule for electronic cigarettes and vaping devices, and it boils down to one point: keep it in the cabin, not the cargo hold.

Why The Checked Bag Ban Exists

It’s easy to think the ban is about smoking or nuisance. The real reason is fire risk. Lithium‑ion batteries in checked luggage can overheat and ignite in the cargo hold, where a fire is far harder to detect and extinguish than in the cabin.

That’s why the FAA’s guidance — and every major airline’s policy — demands vapes be carried on one’s person or in a carry‑on bag. The risk isn’t theoretical; the FAA has documented several battery‑related incidents in aircraft holds over the past decade.

• Carry‑on required: FAA and TSA both mandate vapes in cabin baggage, never checked.
• Battery protection: Prevent accidental firing by turning off or disassembling the device.
• No use on board: You cannot vape or recharge the device during the flight.
• Personal use only: Airlines like Delta specify that vaping devices are for the passenger’s personal use, not for sale or distribution.
• Confiscation risk: If a RELX ends up in a checked bag, TSA is likely to find and confiscate it, causing delays.

These rules aren’t unique to RELX — they apply to all e‑cigarettes, vape pens, pod mods, and even disposable vapes. The same battery‑safety reasoning governs every one.

How To Pack Your RELX For The Flight

Packing your RELX correctly is simple once you know the two big rules. First, place the device itself in your carry‑on bag, not in your pocket unless your specific airline permits pocket carry (some do, but not all). Second, ensure the battery contact points are protected to avoid accidental activation.

Many travelers wonder about carrying spare pods or bottles of vape juice. The standard TSA liquids rule applies here: each container of e‑liquid must be 3.4 ounces (100 ml) or smaller, and all such containers must fit inside a single quart‑sized zip‑top bag. Pods pre‑filled with juice are usually small enough to fit that rule without issue.

If you have multiple devices, each one must be in carry‑on. The same holds for replacement coils or batteries — those go in the cabin too. The FAA has a helpful page on the FAA carry-on requirement for e‑cigarettes, confirming that the device cannot go in checked luggage under any circumstance.

Note that checked luggage rules differ for liquids: a larger bottle of vape juice can go in checked bags without the 3.4‑ounce restriction, but the device itself cannot. That’s a common trip‑up for travelers.

What About RELX Pods And Juice?

RELX pods are small — typically 2 ml or less, well under the 100 ml liquid limit. That means they fit easily into your quart‑sized bag alongside your shampoo and toothpaste. You can carry multiple pods as long as they all fit.

For larger bottles of vape juice, the rules split: in carry‑on, each must be ≤100 ml and all must go in the liquids bag. In checked luggage, you can bring larger bottles, but you still cannot pack the RELX device itself there. Some travelers separate the device into carry‑on and put juice bottles in checked — that’s fine.

The key step: when you reach security, remove your liquids bag and place it in the bin. The RELX device itself stays in your bag; you don’t need to pull it out separately unless TSA asks. Most agents are familiar with vape devices and won’t bat an eye.

1. Place your RELX in your carry‑on before you leave home. Never put it in checked luggage.
2. Protect the battery. Turn the device off, remove the pod, and if possible, lock the button or take the battery out.
3. Pack juice in a quart‑sized bag. Each container must be ≤3.4 oz (100 ml) if in carry‑on.
4. Keep everything accessible. If security asks to inspect, you want easy access without digging.

These steps take under a minute and save you the headache of a bag search or confiscation. Follow them and your RELX will pass through security without a problem.

What Happens If You Break The Rules

If a RELX accidentally ends up in checked luggage, the consequences vary. At best, TSA will find it during screening and confiscate the device. At worst, the bag may be pulled for a manual search, causing you a delay as you’re called back to the screening area.

There’s also the remote safety risk. A lithium‑ion battery in the cargo hold — even one that seems perfectly fine — is a known fire hazard. That’s why the FAA provides airlines with marketing kits to educate passengers about keeping vapes in the cabin.

The table below summarizes what travelers actually experience when they break the carry‑only rule.

The rule is enforced consistently. Airlines like Delta explicitly state that using or recharging a vaping device on board is not permitted. If you’re caught, expect a warning at minimum, and potentially being met by law enforcement upon landing.

The Bottom Line

Your RELX can fly with you, but it must stay in your carry‑on bag. The rule exists for one reason: lithium‑ion batteries are a fire risk in cargo holds. Pack the device correctly, keep pods and juice under the liquid limits, and never attempt to vape or charge during the flight.

The TSA and FAA have laid out these rules clearly — check your airline’s specific policy if you’re uncertain, and if you’re traveling internationally, verify the regulations of your destination country before you fly.
