As simple as that... Probably a dumb question but do you? First time taking flights as a family and I can't for the hell of me remember if people lock their luggage. I don't usually travel with anything worth nicking and obviously they could check your bag. I was wondering about using a cable tie to hold the zips together just from a practical point of view but maybe that's mad.
So what do you do? Luggage going into the hold... Any one fancy refreshing my memory?!
