Just been looking at Easy jet Geneva route in December and trying to work out the load factor , its a bit tricky as Flybe lumped in there as well
Both airlines operated 8 flights so being generous and giving Flybe an average load of 60 pax per flight that leaves Easy jet with an average of 133 pax per flight on a A320 , 180 / 186 seater
All guess work to a degree though !
