I noticed this sentence in the article: "The A380 was also Airbus’s answer to a problematic trend: More and more passengers meant more flights and increasingly congested tarmacs".<p>Problem is, that hasn't been the case in the United States.<p>Or rather, while <i>passenger miles</i> are still up over the past 14 years, both aviation fuel consumption and departures are down.<p>The US hit peak aviation fuel in 2000. Peak <i>departures</i> occurred in 2005, likely due to a shift to smaller aircraft. Total passenger miles remain up since then, due largely to increased load factors -- reduced seat pitch (spacing) allowing more rows aboard aircraft, and improved scheduling packing more people into those seats.<p>I discovered the peak aviation fuel element when looking into one of several rather unconvincing projects aimed at providing biofuels for commercial aviation (the proposals simply don't scale).<p><a href="http://www.reddit.com/r/dredmorbius/comments/1wo2hl/boeings_biofuel_breakthrough_less_than/" rel="nofollow">http://www.reddit.com/r/dredmorbius/comments/1wo2hl/boeings_...</a><p>Using the US Department of Transportation's "RITA" data, 2013 aviation fuel consumption was 17% <i>below</i> 2000 levels, and less than half of the 2000 prediction.<p><pre><code> Year 2000 FAA Est 2014 RITA Actual % Difference
