Per PAX and route this gives a consumption of 21.4 g/PAX/km = 0.03 l/PAX/km = 0.0147 gal/PAX/NM, assuming a cruising speed of ~900km/h = 486KTS. Restating this as a mileage, one gets to 68.13 NM/PAX/gal = 78.4 statute miles/PAX/gal. So yes, I think ~80 stat.mi./PAX/gal is a reasonable number -- at least for the A310.
