Where are 2-Day Air UPS packages routed from San Fran to Denver?

I don’t want my wine sitting in Kentucky, Arizona or Texas, if that’s the typical route.

Thanks in advance for any insights.

Whenever I fly SFO/OAK to Denver the flight is direct. Then again it depends on who is flying. UPS had their own fleet though. I tracked packages from East to West but not West to East. They have never stopped in Denver.
