Well yes it depends.
I guess i should have said something more like "well run airlines with
incentives to lower ticket prices"

You can go thru it, but typical numbers seem to be 30-50%. This year,
with lower fuel prices and ticket prices steady, the percentages are lower.

Indeed the Falcon 9 propellant cost comes in at about $40/lb of payload
with expensive RP. Commercial airlines do about 50% of their costs as fuel.
I thought that the fuel was a fairly small portion of the cost to run an
airline not anywhere near 50%. I am still sure the percent of their budget
as fuel is still significantly higher than for rockets so your point still
stands. Here is a video with some decent sources on the cost of a plane
ticket. Many of these costs directly translate to airline costs.

But if you are still fixated on SSTO, then... I guess there's no hope
for you. Even with a Sabre engine, which is just about perfect for a
TSTO booster..
SSTO, TSTO, witches on brooms, I don't care. I am focused on low cost
and don't care how it is done. I actually started with looking into a
space elevator proposal to get (step) taper out of a constant diameter
cable, and tried hard to get Kevin Parkins microwave heater to orbit
scaled up to where it could support a power satellite project.
If anyone has another proposal that will get the cost down below
$100/kg to LEO, I would sure like the read the proposal.
