Where was her Kingston security cord?
Whenever I travel I always leave my Kingston security tether in place so when i have to wait around transportation terminals I can thread the cord through suitcase handles and still know all is safe (except at Heathrow where a Plod told me to carry them)..
At check in counters, I treat it like a dog leash - around my wrist.
Going through the X-ray machine I thread the tether through my jacket / coat sleeves to stop things disappearing.
When riding the Chiltern Line (great service) I place my laptop on the rack and keep the Kingston around my wrist. I can even snooze knowing all is safe.
Never lost a computer (or anything) in many decades of travel except when travelling with Air Canada when they managed to lose my checked baggage.
