We arrived yesterday #155 , LHR to LAS. We were in the economy cabin. The flight landed at 2:49 PM ahead of the scheduled time of 3:25 PM. We used Global Entry, there was no one else using the kiosks, not all were operational. We had carry on only and were on the other side in minutes from exiting the plane. Being cautious we had booked our southwest connection to PHX for a 7:45 PM departure, so our wait was long. There is a tram that we used to access C gates for our SW flight. It was very easy. We could have easily taken the earlier 5:25 PM flight to PHX, but we felt it was too close.
