Wheeled luggage including an extendable tongue permits use as a hand-truck to transport an additional piece of luggage supported on the extended tongue. The wheeled luggage may be similar to conventional wheeled luggage, but further includes a tongue movable between an inactive and active positions. In the inactive position, the tongue is positioned within a footprint of a bottom of the luggage. In the active position, the tongue extends beyond an outer edge of a bottom of the body to provide supportive structure on which the additional luggage may be placed. The structure of the extendable tongue may have various suitable configurations. A mechanism may be provided for moving the tongue between the inactive and active positions while the user and luggage are in an upright position. An optional strap and/or strap retraction mechanism may be provided to securing the additional luggage.
