Just to let you know... I called Dubai customs to ask the question about e-cig (I want to know once and for all)
Went something like this...
"Hello can you please tell me if e-cigs are banned for transit pax into DXB?"
"One moment madam...... I will check"...
*Hold music*
50mins on speakerphone
Other end hangs up
Sorry, no more enlightened than I was the other day. Tried though! Lol. Maybe email will have better results...? Ground staff give me different answers as well....
