Currently virtually all type rated F/Os are coming through TRSS. Command is based on 3000 "Factored" hours (details are on the website). Once on line you'll fly 700-900 hrs per year, so you'll make up any shortfall quickly, then some assesment rides and a Command Assesment sim. That puts you in the pool for upgrade. The company continues to expand at 15-25% a year, so it's still going to be one of the quickest upgrades around.
