Aircraft & Seat utilizations are very important figures for every airline. They also gives a good indication as to how 'healthy' that airline is during periods of economic trauma such as now.
The CAA collects statistics and publishes them eg
this tableYou can see VS has an aircraft utilization of about 15 hours a day - just about the highest efficiency of all.
Only the brand new 777s of BA top the list.
There is a downside to this: when an aircraft goes tech. there are few to act as immediate replacements; giving rise to delays. VS has higher delays than some!
VS is also extremely good at filling seats - the 744s have over 85% seat utilization at the moment - for a scheduled airline that is extremely good - only charters exceed that - BA aircraft are in the 69% - 81% range.
Very much a matter of achieving the right commercial balance - VS sales & ops. are particularly good at achieving that high efficiency of both seats & aircraft, which allows us to have good value for money transport without the airline going bust!
