You can print your boarding pass at home and go directly to the gate (after passing through security, of course). You won't have to wait on line to check the luggage and you won't have to wait to pick it up when you return to your departure airport. I know we have waited over an hour at Newark airport for our luggage to come through the turnstile. And you won't have to wade through the crowded airport with your luggage in tow.
Here are a few services that will deliver your luggage for you:
