I still don't believe in those TSA locks - saw the programme last night and (whilst it was still on) emailed the programme's email address:
"Have just been watching your programme this evening (25/05/06). There was a feature on "locking your cases" for trips to/from the USA.
During this programme one of your presenters recommended the "TSA Approved" padlocks available to buy (paraphrasing that the TSA can use the special code/key to access your locked cases and relock them after searching them).
I myself bought a couple of these TSA approved padlocks last December, for a trip to the US in January. We flew to the US and flew four internal US flights before returning home to the UK. By the time we got home, both of the TSA approved padlocks had disappeared from our cases (they had either been taken off and not put back OR they had been cut off and discarded). Apparently this is not an uncommon occurrence.
I honestly believe that TSA Approved Padlocks are a waste of money. In light of the current policies in the US, your case is very likely to be opened (by either official TSA staff and/or more "criminally inclined" airport staff). There is little you can do to stop them (even if you place TSA Approved locks on your luggage, chances are they will not remain on them).
Probably the most effective (and economical) thing you can use are "zip ties" -- about as effective as a padlock (if someone really wants to get into your luggage they will anyway) and at least a bit cheaper to replace when they go missing."
Go ahead, buy them, but don't be at all suprised if you don't get them back again. At Orlando they MAY be better at replacing the TSA locks and putting a note in...
