I don't think this blog post's headline is quite right. "Losing a child" is putting a child on BOS-EWR instead of BOS-CLE and not noticing the problem until the child's family in Cleveland calls the parents and the parents call Newark, http://content.usatoday.com/communities/ondeadline/post/2009... .

If my luggage didn't make a connection and I arrived at my final destination without it, I would think of it as "lost luggage." Would it matter to me if it was stuck in the connecting airport or sent elsewhere? No, it did not arrive with me, the airline lost it, even if temporarily. In lay person terms, the luggage is lost--the airline lost a child, yes.
Sometimes it goes on an earlier flight, as was the case with my bag last month flying IAH-LAX on United, a route where United has a dozen flights a day. If you're connecting, your first flight may have been delayed and they couldn't get the bag from one end of the airport to the other.
I'm not trying to say the situation doesn't suck but there is a certain logic, twisted it may be, to airline operations.
And I'm certainly not trying to defend United's actions in this instance.
