"didn't pack her own bags". Oh come on. Has anybody ever in the history of humanity not packed their own bags?

I agree JK! It was either my mother packed them for me when I travelled to and from the USA and Ireland. Later in life, my ex-girlfriend or my partner packs them for holidays.

Not many men pack their bags if they are not single.

You'd be amazed, a lot of men let their wives pack their bags for them. I can't imagine anyone else deciding what clothes I'm going to wear

Actually it's not that unusual for those who organise smuggling to pack cases for a stupid "mule" who collects the case on the way to the airport.

While I have no knowledge of this case remember drugs are still often concealed in hidden compartments.

They can always be seen now via x-ray machines but those who organise these runs rely on quantity with not a single thought for the mule's safety rather they may have 2 or 3 mules on the same plane hoping 1 or 2 get through undetected.

Why would anyone want to carry or hold a stranger's suitcase at an airport?

I don't think they are mules these days, but chancers.
