Not all "kerosene" is the same. Jets use Jet Fuel A which is ~$5/gallon while Merlin engines use RP-1 which is ~$100/gallon.
Also, on the latter, you need a similarly sized tank of liquid oxygen that the jet gets for free from the atmosphere.

- moralestapia 5y agoSure, but we were talking about fuel cost. >Starship's methane is cheaper than Jet A. Is this true yet? I'm honestly unaware of it. I've heard they were planning on it to be quite cheap when they find a way to extract it from the atmosphere, but don't know how far they are through that.
