This could be a good place to re-post a quote from the well-travelled Prof. Beard:
I have travelled to and from the following airports:
Manchester
Birmingham
Schipol
Charles de Gaulle
Frankfurt
Pisa
Genoa
Alicante
Montreal
Newark
JFK
Chicago
Atlanta
Houston
Long Beach
San Francisco
LA
Phoenix
Austin
Philadelphia
and probably some others Ive forgotten
Never had any problems. I keep everything in carry-on, juices in the "liquids bag". You must NOT - repeat NOT - put spare lithium batteries in your checked baggage (its best not to put anything containing a lithium battery in checked baggage but "loose" lithium batteries are a big no no in checked baggage)
You need to give some thought as to where you carry your vape supplies when travelling.... but openly vaping on the plane is an invitation to a disagreement with cabin staff imho as other passengers see vapour and assume it's smoke.
Nothing wrong with discretion.
Just saying.
