Abstract: A carry-on package bag includes a bag opening and two primary bag sheets opposite to each other. Top edges of the primary bag sheets collectively define the bag opening. Each primary bag sheet includes a first fold line, a first foldable sealing section below the first fold line, and a second foldable sealing section between the first fold line and the top edge. Each first foldable sealing section has at least one first carrying hole. Each second foldable sealing section has at least one second carrying hole symmetric with respect to the first carrying hole about the first fold line. The second foldable sealing sections are foldable along the first fold lines toward the same direction to be overlapping and stacked on the first foldable sealing sections so that the second carrying hole and the first carrying hole correspond to and communicate with each other.
