All over the world there more or are organized luggage stealing going on in airports. We had a huge scandal at the Stockholm airport a few years ago where some staff where regulary opening bags & grabbing whatever items they liked.

So padlocks is a good idea.

In the US airport security staff will cut the padlocks on the cover if they think the contents is anything they want to take a look at.

Since I do not want to buy new padlocks all the time I seal the zippers with plastic straps used for electrical cables. Easy to cut for the security staff but I know if someones been inside.

In other places I have never had anyone requesting me to remove the padlocks when checking in.
