Abstract: A portable baggage carrier having the form of a shallow enclosed housing has straps for securing the carrier to one side of a suitcase. A side panel of the housing opens to provide access to a pair of wheels pivotably mounted to lie flat within the carrier, which extend downwardly below the carrier and articulate through 90 degrees upon being deployed to an operative position. A collapsible handle also is stored within the housing, being accessible through the side panel for attachment to the top of the carrier. Closure of the side panel with the wheels deployed serves to lock the wheels in their extended position.
