You will be doing well to get into the right hand seat with any of these with no commercial,airline experience or a type rating on their type let alone start thinking about command. I know for a fact that guys at Monarch just about to get left hand seat in the main will have over 5000 hours'on type'. I also know as has been stated that the guys doing there command sims as we speak at TC have been with the company for around 15 years. If command is a big thing for,you then go get a 737 type and join Ryanair.
Good luck
