What's the proedure when taking a Tablet PC through security when departing on an international flight?

What's the proedure when taking a Tablet PC through security when departing on an international flight? Do I have to remove it fr2om it's cover/sleeve, as for a laptop? If not, can it be left in my carry-on bag as per my last domestic flight? Any advice would be appreciated, thanks.

In my experience it varies from one airline, or even country or airport, to the next.

With some you have to take it out of your bag, just like a laptop, with others iPads and tablets can stay in the bag. Some security checkpoint staff, when doing their announcement to passengers waiting in line, will specifically include "iPads and tablets" in the laundry list of kit to be removed from the bag.

As a result, I've given up bothering and just make it a habit to remove my iPad from my bag when doing through security.

Yeah I had heard that the official US policy was that if it uses a SSD hard drive (all tablets + all ultrabooks such as the macbook air), you don't need to take it out. Not sure why, maybe because its the traditional 2.5" hard drives that are so messy and hard to look through in the xray machine. I have tried ignoring the staff and keeping my ipad and macbook air in my backpack, and gotten it through without any problems, but I generally take the macbook air out, cos if they call me back it wastes even more time. 

David's absolutely right. I'm sure there are regs but nobody seems to follow them.

After a couple of times where my Kindle led to a "this bag needs to go back through the machine" I've even started taking out my Kindle. I'd rather spend five seconds at the start every time pulling it out than god-knows-how-long waiting in the sin bin to be allowed to leave.

I fly with a laptop and tablet (iPad) and in my experience departing from Syd, Melb, Bris and Perth on international flights I havent had any issues only taking out my laptop for separate scanning and leaving my iPad in my carry-on. Not sure if your question was related to international flights departing from Australia or international flights in general.

Same goes for LAGs. I don't have mine in a see-through resealable bag, it's in a QF First amenities bag and the only place I've been stopped is Perth. Managed to get through AKL, LAX, OOL, SYD, MEL, BNE, NRT and Hong Kong with it...

Yes, LAGs is a very funny one... despite the constant chorus cries of 'must be in plastic bag', I've always put mine in an amenities bag (I use different size bags for different types of amenity packs, as I have a few designed for different 'grab-and-go' situations) and the only time I've ever had the 'plastic bag' rule enforced was at Nadi, Fiji!

So, these days I pack a suitable-size ziplock plastic bag in my carry-on, same pouch as the amenities bag, just in case I have to quickly trasnfer items from the kit to the bag.
