Yes, I remember watching the inaugural arrival from the top of the terminal 3 parking garage at PHX
Here's some pictures we took during the first couple weeks of service. These are from early February 1989, not the inaugural flight but close enough.
The picture direct linking doesn't work, so here's links to click on to get to the pictures.
