Airplane on the ground. I went out to drive the electric tug with the cart on the other side.  Then the plane [was] coming. He's already on the line then the [marshall] is receiving the plane. Then I just saw the plane stop and heard the loud noise.  I looked underneath the plane and saw the cart tilted.
I was in the ready room waiting for my flight to come in. As soon as the monitor showed that the aircraft was on the ground I went outside to look for my lead and gate crew who were not out there. The aircraft was already on the line waiting to be brought in. I went back inside to look for my gate crew and did not see them in there; so I went back outside and saw that I had a wing walker out there ready to help bring the aircraft into the gate. I walked out to the gate to marshall in the aircraft; so it did not have to wait on the rest of the crew to arrive. I took a quick look at the operational safety zone to see if there was any FOD or equipment in the way and it did not appear to me that there was. I was in a bit of a rush to get the aircraft in; so I did not do a FOD walk 5 minutes before it came in. My wing-walker was on the Captain's side of the aircraft walking it in as I started to bring it into the gate. The front tires were a little off the line as it was coming in; so I was paying a lot of attention to making sure that he started moving back toward the lead in line and not veering away from it. The pilot started to steer back towards the center of the line and it was getting to the point in which I had to start slowing him down to stop and it was at that point that I heard a loud bang and I looked over at the copilot's side and saw that the wing tip had hit a baggage cart sitting at the edge of the operational safety zone possibly because I had a hood over my head because it was cold and windy. I then gave the X stop signal to the pilot. I did not see the baggage cart sitting there when I looked over the gate as I was on my way out to marshall him in. After everything had stopped I went inside to get a Supervisor.
