Always fascinates me that time to command is a primary concern to pilots these days. I was so grateful to get into an airline I never considered it until it started getting close on the seniority list. It has always been around 10 ten years for a narrow body command give or take a couple of years. The aeroplane can't go without a co-pilot so you are still vital to the operation. It's a great way to learn too. Some of the captains I flew with had terrible CRM and it helped me to do better when it became my turn. As for the widebody dream, talk about the grass is greener. Terrible job sitting there for 14 hours, always tired and never home. You only fly the instrument panel, it doesn't matter what's bolted on behind.
