The fuel economy on long-haul flights today is actually worse than shorter routes because older airframes couldn't carry that much fuel so would stop to refuel. Keeping the extra fuel aloft for a Perth Australia to London run imposes a large efficiency penalty. I'd bet the reduction in fuel consumption probably is closer to 90% when comparing jets today to piston prop planes, rather than the 707 and DC-8 jet aircraft of 1960. I suspect economies of scale created by lowering fuel cost is the real driver behind lower flight costs. With much larger production runs the cost per aircraft on a per seat basis is certainly far lower on an inflation adjusted basis than the 707 or DC-8. Although airlines had a short-term cost savings flying surplus military aircraft after WW-II.
