E-cigs in cabin baggage
Just back from a LHR-SOF-LHR with some E-cigs in my carry-on (with no intention of using them on the flight). At both airports there was much staring at the X-ray image with subsequent questioning and contents inspection. At LHR T5 a supervisor was called. Having clarified what they were I was able to go on my way.
Conclusion - a) They look suspicious on the X-ray and b) Security staff aren't familiar with them yet. If I travel with them again I'll take them out of the bag for separate screening just in case...
