I think we are looking at different ends of the market, I'm using a search of the retail price at airfields near me in the last 30 days. (My parameters don't get reflected in the URL, you will need to choose some to get results.)
I suspect at "airline" scale there is a large discount over the full service pump prices I'm seeing. This might change the percentages to 10% and 25%.
It's also possible I'm seeing the "putz price". That made up price that "no one really pays", unless you are that guy who doesn't know better and does.
42 gallons in a barrel of oil. So the bottom price is going to be about (oil price)/42. Lots of complications in converting a random quality oil into jet fuel at an airport, but at scale you might add 10% to 20%. With current oil prices this does work out to around your $1.10/gal price.
