Stolen camera from checked in baggage
Just came back from a trip to Europe on United and had the frustrating experience of having my camera stolen from a checked in bag. United tells me that I shouldn't have put any electronic items in my bag in the first place.
They also say that they require passengers to not lock the luggage when checking it in post Sept 11th.
So the moral of the story is that don't put anything precious in your checkin luggage and try to carry it with you into the cabin.
Although my experience with United has been less than satisfactory, I tend to believe their explanation that other airlines have the same policy.
