Delta Air Lines Buys Sustainable Aviation Fuel For Los Angeles Hub
Delta Air Lines has purchased up to 10 million gallons of sustainable aviation fuel for use at its hub at Los Angeles International Airport (LAX). (aeroxplorer.com) More...

I guess this a step in the right direction - but my understanding is that the production of bio fuels( especially ethanol) typical produce more green house gases than standard hydro carbons.
The article isn't long, and it answers your assumption about GHG in the production of biofuels (80% reduction from traditional jet fuel production).
You need to read the article carefully, very carefully as the wording is very misleading.
What it says is "the production process can produce up to 80% fewer carbon emissions than traditional jet fuel". The key word is "production". It says nothing about the CO2 emitted in use or the land area used to grow the material that goes into the production process or what it takes to grow the material.
The real problem is that there simply no way of scaling this up to be anything more than a rounding error. We run out of land before that ....if we want humans to actually have food for people to eat.
THe only way that the aviation industry is going to get anywhere near zero carbon is via direct air capture (DAC) where the cO2 is removed from the atmosphere. The problem with DAC is that we really don't know how to do it commercially today.
To get to zero carbon, or anywhere near it, a LOT of work needs to be done....and sadly it is not getting done at anything close to the rate it needs to.

how much does it cost to make? how much energy does it take? where does that energy come from? what products are used to distill/refine it? will it really save on anything??? think that's what D Purtz was asking?
Only few seem to know.
I bet that purchase wasn't cheap
