Using on-line travel sites

If you’re traveling somewhere that you can’t get to non-stop, is there a way to find a connection through a specific city? For example: on the way to Hawaii, can you pick to go through SF?

Yep. Just did a quick search and both Kayak.com (an aggregator) and Continental.com (an airline) have search options for “multiple destinations.” I suspect other aggregators (Hotwire, et al) and airlines (United, Delta, Southwest et al) have similar options.

shoulda tried KAYAK!
