Maybe have a calculator on the website that lets you put in the start and end of your journey, tweak things like how far in advance you want to arrive at the airport with some set minimum (e.g. need to arrive at sfo at least 1 hours before), then can compare your offering vs the standard home-sfo-lax-end destination. it's the kind of info most people would have to piece together with Google maps, having it in the site would be pretty easy to do, and where there is a big time saving, becomes a pretty strong motivator to "sign up now"
