Based on what I've read so far, it seems like some passengers with carryon luggage are able to get through the line faster. I typically only bring a carryon, but my wife usually checks a bag. We'll be traveling with our 6-year-old, so I'm hoping it might be possible for the two of them to get through the line quickly with my carryon and then pick up our rental car while I continue to wait in the line.

Does this seem like it would work? I just don't want us all to be waiting if it's only a matter of one bag.
