I plan to check my luggage this trip to France but am confused about whether to lock it or not. Had thought of using a TSA approved lock - but the clerk at Travelsmith said that's only good in the U.S.
A friend said to just leave it unlocked (makes me nervous).

I have a theory on locked luggage. It tells the thiefs that "she has something she doesn't want me to have in here, maybe I want it" There has NEVER been a lock invented that a thief in TSA and/or baggage claim can't defeat. (And if the TSA can open you lock, you can bet the key is also in the hands of the baggage guys)

Put a twist tie on the zipper and go.

The requirement to use a TSA lock is only in the United States. If you want your luggage locked, go ahead and use a TSA lock.

Outside the U.S. a lock is a lock. A twist tie is a twist tie. Both can be defeated.

If you want some sense of security, use a lock. I do it on every trip, regardless of where I'm going.

I use twist ties or cable ties simply to hold the zippers closed. I don't put anything valuable in my suitcase.

I use cable ties. Cheap, easy, and help you identify your bag on the carousel. Just use your nail clippers to cut it when you arrive. Then put another cable tie on it for the return journey . . . .

I never lock on airplanes. I sometimes use those zip tie thingies on a train if I can't see my bags.

My main rule of packing: NEVER take anything that would you hate to lose. I know many people (my kids included) like to take their favorite things. But I've gotten over that and now I don't worry about stolen or lost bags.

Interesting thread which only applies to the US, Be aware that if you plan to use nail clippers to open the twists, whey are not allowed on board and could well be confiscated by the security in Europe. So just lock the case with your clippers inside.

My thanks to all who answered. I'll just do the twisty things.

I use small black cable ties. I put a pair of nail clippers in a side pocket to snip them open. Leave a little slack in the cable ties so you can get the clippers under them.

Nail clippers are allowed in checked and in carry-on luggage. See http://tinyurl.com/ptxdw.

Never put any valuables in checked luggage whether you "lock" it or not.

Nail clippers definitely ARE allowed in carry on. In Europe - what isn't allowed are the pointed nail files attached to some clippers. But plain ole ordinary nail clippers - no problem at all. I've seen more than one European security screener open up a nail clipper and snap off the file and return the clippers to the passenger.

OK, but the nail clipper then depends on what type. Best be forwarned then, so i am pleased that i raised it.

But the qeustion was about checked luggage. So you use plastic cable ties on the main compartment & slip the nail cutter into an exterior zippered pocket of the suitcase which you don't put a cable tie on.
