The priority data on the front page of the patent in question should tell you.

Jim's answer focuses on the situation where the PCT application is the priority document.
 
If the PCT application used the US filing as the priority document, then that shoud show up in PAIR.  Also the PCT application would typically publish around the same date as the US application.

Richard's right.  You could search for priority document information over at espacenet.com.  You'd search based on the US application number.
 
I haven't used it recently, but I hear this works well, too:
