Max,
Just to clarify the accelerated command program. We only use accelerated command upgrades if there are no 3 year first officers available for upgrade.
On the airbus, there are many 3 year first officers who are waiting to upgrade, so there will be no accelerated command's in the next year and a half or so. The story might be different on the Boeing. You can NEVER expect to upgrade in 18 months, as many 18 month+ dec/accelerated f/o's
will tell you!
