The SAS in-flight magazine (Scanorama) has details about aircraft of the airlines at least partly owned by SAS (such as Estonian Air, Air Baltic, etc.). Among the information provided there is operational costs. I noticed that cost per seat per kilometer for the same aircraft type and modification and same number of seats and with the same engines differs in different airlines quite much (by as much as 20% if I remeber correctly). Why is it so?
