I still find it hard to find the rational for the OS concept in these difficult times. Management at BA seems to be spending all its time (see last 3 weeks of BA News) on this minor part of its business, BA needs £25Mpd revenue just to stand still and at best OS is going to generate .3% of this sum!! if it operates full?
The only way any airline is going to survive, say $150 Oil, is by using the most fuel efficient a/c and charging the right price for the service. At present an OS a/c is costing about $ 75,000 round trip on fuel, thats a huge amount to be shared by a small number of pax.
