I was in PHX terminal 4 on the Cactus international side and some lady accosted me, very rudely, asking how to get to her gate. I asked what airline and flight, and she got even ruder and irate, apparently running very late.
She was on SWA. The short way to SWA side would be to take a moving walkway to the other side of the terminal (3-5 minutes). The long way would be to walk about a mile, all the way around, exiting and then re-entering security. I just wasn't in the mood that day so I suggested the long way.
