Can I take hairdryer with me on hand luggage
You won't be able to use it on the plane.
Don't know of any restrictions on hair dryers.
Taking it on plane should not be an issue - normally.
Do check voltage, and amperage, for use at your destination, if traveling internationally.
I am quite certain that you can fly with hairdryers in the cabin, however I'd recommend you don't use it, even though it might be allowed in the toilets. Better to ask the cabin crew or airport staff
Donut. What are you talking about?
As long as you're not then carrying it down to the bottom of the Grand Canyon, why ever not?!
Doreen: Why would you even think it would be an issue?
