FWIW, I recently took a flight from Belgrade via Istanbul to Birmingham (UK). Hand luggage only, no checked luggage.

At Istanbul they took my laptop from me, gave me a receipt, packed it in bubble-wrap, put that in a suitcase, and put it in the hold.

Yes, I got it back in the baggage reclaim area, but it was cold - seriously cold - I didn't dare turn it on for several hours to let the disk warm up slowly.

This is making international travel a complete crap-shoot.

Take precautions people.
