RPKs would be a better measure than passengers though when comparing fuel stats. Those figures at first glance more likely indicate that pax are taking more shorthaul trips which is not necessarily good news especially where an alternative such as electric trains is out there, in theory. However displacing internal British traffic to rail requires both huge investment in high speed rail and more nuclear power and other low GHG sources to ensure that the CO2 does not merely displace from aviation fuel to coal.
For me I would put a fairly flat levy on air travel, since the longer the trip the fewer the (feasible) alternatives.
