Are you absolutely sure about that? Per passenger mile on a modern full
aircraft?

You do have to look only at first class passengers on a long haul flight
to justify the claim. According to DEFRA, those passengers are
responsible for 322.3 gms of CO2 equivalent pre passenger kilometre
(gCO2/pkm).

The averages for aircraft a
Short Haul flights 95.9 gCO2/pkm
Long Haul flights 110.4 gCO2/pkm.
Domestic flights 163.1 gCO2/pkm

For comparison, some other figures a
London Underground 73.6 gCO2/pkm
Local London bus 86.3 gCO2/pkm
Tyne & Wear Metro 103.6 gCO2/pkm
Hybrid cars average 139.0 gCO2/pkm
Local bus (outside London) 185.9 gCO2/pkm

Electric cars, charged from the mains:
France 12 gCO2/km
UK 75 gCO2/km
China 115 gCO2/km
Note this is per car km, not per passenger km
