For the most part, I don't think the amount of time you would spend travelling to a gas giant for 'free' fuel would be worth it. Obviously it's going to vary between systems due to where you dock, but lets use Earth's system as an example.
The closest gas giant is Jupiter. At 1G I think it takes at least a week to get there, then you'll spend the time gathering your fuel, then processing it, and then you have to maneuver 100D away before you can jump.
Passengers won't like that, unless they are desperate to get off the planet or frozen. You still have your ship operation costs, such as wear and tear as well as other consumables and supplies.
Frankly the cost of filling your tanks with unrefined fuel locally has got to be much cheaper.
Anyone have the transit tables handy to calculate times?
