Just looking at a UA ticket from here to USA and back, and there was near on $US100 of "Fuel surcharges" on it RT. i.e. US$47.35 each way.

It got me to wondering. If all 347 pax on a full plane pay about that = ~$US17,000 a one-way journey in surcharges, what % of the actual cost of jet fuel does that typically represent being paid direct by the passenger on TOP of their ticket? 5%? 10%? 25%? 50% etc.

Someone here will I am sure know what the average burn on 13.5 hours is, x $$ cost per ton cost of jet fuel.

My curousity is - is this fuel surcharge just covering the recent fuel hikes, or is it darn near paying for the entire United fuel cost on a flight these days?
