Another thing to consider these days is that any cadets joining now will have little chance of a command for a long time. The fleet expansion will be complete within 18 months when 300 aircraft is reached. the fleet will then start to reduce in size, and promotion will only be into "dead mans shoes" I think long term (15 years) in the right seat could soon become the norm. Many may never even see the prospect of a command, with so many F/O's all of similar age and experience, and so many young captains.
