I'm new to Amex flight booking engine. I'm looking for ex-SFO J fares and am flexible as to dates (and cities, for that matter).

So far it seems that I have to select a departure date and a return date to get a quote. Does the flight engine have a low fare finder feature or an easier way to look at daily fares one month at a time, for instance? Or am I stuck with the brute force way of having to enter each departure date and return date pair individually?
