Tha Unless the Bag falls off the plane in flight, it is almost never Å*ost? Go visit the lost baggage area at an airport and you will see that they know WHERE all the bags are. They just donÃÕ know WHO they belong to. The Bags arenÃÕ lost, the owners are!
There are other possibilities.
Some frineds of ours went on a trip-of-a-lifetime golf outing to Scotland. Their golf bags were apparently never loaded on the plane, and they spent the first three days playing with some very inferior rental clubs. Fortunately their own sets arrived just before they played the Old Course at St. Andrews.
My wife and I took a trip in which our plane tried and failed to take off twice (quite thrilling, BTW) before the airline gave up and put us on another plane on another airline. It took two days for our bags to arrive.
I am most likely to carry my reg in my carry-on for a reason others probably haven't considered. With the new charges for bags, I work hard to get everything into one checked bag. That means carrying some things in my carry-on, which does not get weighed. That usually includes my reg set because it is heavier than a lot of other things and because if there is any delay in my luggage, I have it.
Otherwise I would have no fear of including it in my checked luggage.
