Just to give more details on DFW, I was at the Santiago gate (with a helper) from 6:30pm to 9:30pm. I saw everyone that boarded the plane and there were no teams. They would have had to get on the plane at a time different from the other passengers, or in the few minutes I walked around to other gates, shops, etc, looking for them. I asked two gate workers and they had seen no teams (I feel pretty comfortable they weren't lieing to throw me off). I feel pretty comfortable that the teams did not get on that Santiago flight.
