Vape Juice (E-Liquid)
Vape juice follows the standard liquids rule — 3.4 oz per bottle in carry-on, no limit in checked bags — but the vape device itself must always stay in carry-on.

Carry-on details
Allowed with conditions. As a liquid, vape juice/e-liquid must be in a bottle of 3.4 oz (100 mL) or less to fit in your carry-on liquids bag — TSA goes by the bottle's printed volume, not how full it actually is.
Checked-bag details
Allowed. Unlike the e-cigarette/vape device itself — which must always stay in carry-on because of its lithium battery — the e-liquid alone has no quantity limit in checked baggage.
Quantity limit
3.4 oz (per container)
Special instructions
This entry covers the liquid only. The vaping device/e-cigarette itself is a separate item that must travel in carry-on baggage at all times and is never allowed in checked bags.

- Yes — the liquid itself has no checked-bag quantity limit. Just remember the vape device (the battery-powered part) must stay in your carry-on, never checked.
- How much vape juice can I bring in my carry-on?
- Each bottle must be 3.4 oz (100 mL) or less, and all your liquid bottles together need to fit in one quart-size bag, same as any other liquid.
