Vapes and e-cigarettes on a plane
The short answer: in your hand luggage, not your checked bag. Here’s what the official pages say, 22 October 2026.
Flying from the UK
GOV.UK’s table for flights to the UK lists e-cigarettes as allowed in hand luggage and not allowed in hold luggage. Vape liquid in hand luggage also counts as a liquid, so the 100 ml container rule applies at most airports (check liquids).

Flying from the US
- TSA: “Electronic smoking devices are allowed only in carry-on baggage.”
- Take effective measures to prevent accidental activation of the heating element.
- Each lithium ion battery must not exceed 100 Wh (lithium metal: 2 grams lithium content).
- Check with your airline for any limit on the number of devices.

Arriving in Great Britain
Your personal allowance is up to 50 ml of vaping liquid. If you bring in more, you pay tax and duty on all of it. There’s no allowance if you’re under 17.
